And a display device assembly 110 for coupling the main body 100 and the hinge 124, and the display device assembly 110 includes a flat panel display device 111 therein. The case 122 which protects and accommodates is provided.

In addition, referring to FIGS. 2A and 2B, which illustrate the conventional display device assembly 110 in detail, the flat panel display device 111 may include a plasma display panel (PDP) or a field emission display (FED). In general, a liquid crystal display device is used, and the liquid crystal display device includes a liquid crystal panel 112 and a light distribution device (not shown), and supports frame 114 along the edges of the liquid crystal panel 112 and the light distribution device. ) Is bordered. In this specification, the liquid crystal display device including the support frame is referred to as a liquid crystal display module and a flat panel display module.

The display device case 122 is hinged to the main body case 120 accommodating the main body so that the display device assembly 110 can be selectively opened and closed on the main body 100. The hinge connecting portion 124 of the hinge protrudes from an upper portion of the main body case, and the main body case 120 and the display device case 122 are connected to the hinge connecting portion 124 via a hinge arm 126. . Therefore, the display device assembly 110 is rotatable with respect to the main body case 120 at a predetermined angle.

Fixing pieces 114a are protruded from both sides of the support frame 114 of the liquid crystal display device 111, and coupling pieces 114b are formed at the lower edges of the support frame 114, while an inner surface of the display device case 122 is formed. A plurality of coupling ribs 122a are formed to be coupled to the fixing piece 114a of the liquid crystal display 111.

In the assembling process of the liquid crystal display device 110, the tip of the hinge arm 126 is first fixed to the coupling piece 114b of the support frame 114 with the screw 128, and the fixing piece 114a of the support frame 114 is fixed. ) And the fixing rib 122a of the display device case 122 are fastened from the top to the bottom with the screw 128 to complete the assembly.

There is a distance d1 by the width of the arm 126. In addition, the coupling piece 114a protrudes from the support frame 136 to occupy space by the width d2 of the coupling piece. As a result, a space (d1 + d2 = D) is formed between the liquid crystal panel 112 and the edge of the display device case 122, thereby increasing the ineffective display area of the liquid crystal display device 110, that is, the flat panel display device. There is a problem that the display area of 112 is reduced.

Accordingly, the present invention has been made to solve the above-described problem, and is a portable computer capable of maximizing the display area of an image display panel by minimizing an invalid display area generated when the image display device is fixed to a hinge and a case. And its assembly method.
