This application claims priority from Korean Patent Application No. 10-2007-0005933, filed on Jan. 19, 2007, the disclosure of which is incorporated herein by reference in its entirety.

1. Technical Field

The present invention relates to a display device, and more particularly, to a display device with improved productivity, and a case for the display device.

2. Discussion of the Related Art

Liquid crystal display (LCD) devices have become popular due to their smaller size, lightweight and improved performance when compared with conventional display devices.

The liquid crystal display devices are being employed in information processing devices including middle or large-sized products, such as monitors, TVs and the like as well as smaller-sized products such as mobile phones, personal digital assistants (PDAs), portable multimedia players (PMPs) and the like.

A display device may include a display panel, an accommodating member enclosing the display panel, and a cover member. The cover member may have a display window exposing the front side of the display panel.

The cover member has been fabricated through processes including punching a metal plate in a hollow rectangular shape and then cutting and bending the metal plate. Accordingly, the central portion cut out of the metal plate remains unused and is wasted material.

Embodiments of the present invention provide a display device with improved productivity, and a case for use in the display device.

A display device, in accordance with an embodiment of the present invention, comprises a panel assembly on which an image is formed, a cover member which comprises a front portion having a display window exposing at least a portion of a front side of the panel assembly and a side portion which is bent from the front portion, the cover member having one or more joining regions where a pair of end portions engage with and are joined to each other, the cover member comprising a first joining part and a second joining part which are formed at the pair of end portions, respectively, wherein at least one of the first joining part and the second joining part include a region stepped from a surface of the cover member, and at least a portion of the first joining part and the second joining part overlap each other, and an accommodating member which accommodates the panel assembly and is joined to the cover member.

According to an aspect of the invention, the first joining part comprises a first front joining part which is formed in the front portion of the cover member, and a first side joining part which is formed in the side portion of the cover member, and wherein the second joining part comprises a second front joining part which is formed in the front portion of the cover member, and a second side joining part which is formed in the side portion of the cover member.

According to an aspect of the invention, an end portion of the first joining part contacts an end portion of the second joining part in a stepped pattern.

According to an aspect of the invention, the end portion of the first joining part and the end portion of the second joining part include a convex portion and a concave portion, respectively, and a concave portion and a convex portion respectively, and wherein the convex portion of the first joining part contacts the concave portion of the second joining part, and the convex portion of the second joining part contacts the concave portion of the first joining part.

According to an aspect of the invention, the first joining part comprises a joining plate, and the second joining part comprises a joining mount overlapping with the joining plate, and wherein the first joining part and the second joining part are calking-joined to each other by punching an overlapping plane of the joining plate and the joining mount.

According to an aspect of the invention, the first joining part comprises a joining plate, and the second joining part comprises a joining mount overlapping with the joining plate, and wherein an overlapping plane of the joining plate and the joining mount is welded using one of a spot welding method and a laser welding method.

According to an aspect of the invention, the first joining part further comprises an extending portion which extends from the end portion of the cover member, and a locking portion which is formed at an end of the extending portion, and wherein the second joining part further comprises a locking groove which is formed corresponding to the extending portion and the locking portion.

According to an aspect of the invention, the locking portion of the first joining part is tightly joined to the locking groove of the second joining part.

According to an aspect of the invention, the first joining part further comprises a joining plate, and the second joining part further comprises a joining mount overlapping the joining plate, and wherein a locking hole is formed in one of the joining plate and the joining mount, and a locking projection, which penetrates the locking hole to be joined with the locking hole, is formed in the other of the joining plate or the joining mount.

According to an aspect of the invention, an end of the locking projection, which penetrates and projects from the locking hole, is deformed to closely join the joining plate to the joining mount.

According to an aspect of the invention, the joining plate comprises a first joining plate and a second joining plate, and the joining mount comprises a first joining mount and a second joining mount, which overlap the first joining plate and the second joining plate, respectively, and wherein the first joining plate contacts an outer surface of the first joining mount, and the second joining plate contacts an inner surface of the second joining mount.
