The auxiliary film 190 is fixed to the front surface of the cover bottom 150 while maintaining the tension of the first polarizer 118 wrapping the side edge of the guide panel 130, And serves to suppress projection of the side edge of the panel 130.

The auxiliary film 190 is disposed at a lower portion of the cover bottom 150, with the left and right ends of the guide panel 130 wrapping with the extended portion EA of the first polarizer.

When the film fixing unit 180 is provided as in the display apparatus 101 according to the first embodiment of the present invention, the auxiliary film 190 may be provided with a plurality of second holes hl2, The auxiliary film 190 and the first polarizing plate 118 are held in proper tension in a state in which the left and right side surfaces of the guide panel 130 are lapped by inserting the film processing means 180. Finally, The bracket 184 overlapped with the auxiliary film 190 is fastened and fixed to the lower portion of the cover bottom 150 by the second fastening means 157 so that the first polarizer 118 and the auxiliary film 190 Can be stably fixed to the lower surface of the cover bottom 150.

At this time, the area of the auxiliary film 190 excluding the portion where the tch is formed is supported by the bracket 184 with a predetermined pressure, so that the auxiliary film 190 is stably fixed on the lower surface of the cover bottom 150 .

7) of the display device 200 according to the second embodiment of the present invention, since the film fixing unit 180 of FIG. 3 is not provided under the cover bottom 150 3). Therefore, the extended portion EA of the first polarizing plate 118 and the auxiliary film 190 are not temporarily fixed. In this case, since the trenches (tch in FIG. 3) are not formed in the brackets 284, The step of fixing the bracket 284 to the cover bottom 150 in the modularization process of the display device 201 may be performed by the second fastening means 157 so that the bracket 284 may cover the cover bottom 150 ), It has a proper tension and becomes a fixed state.

In the display device (101 in Fig. 3, 201 in Fig. 7) according to the first and second embodiments of the present invention, the film is temporarily fixed by the fixing means (180 in Fig. 3) The portion through which the means 157 penetrates becomes the auxiliary film 190 and the extended portion EA of the first polarizer is supported and fixed by the bracket 184 in FIG. .

That is, a portion penetrated by the second fastening means 157 between the cover bottom 150 and the bracket (184 in FIG. 3, 284 in FIG. 7) is the auxiliary film 190.

The second polarizer extensions EA themselves are temporarily fixed by the fixing means 180 of FIG. 3 or are not fastened by the second fixing means 157, The film is fixed temporarily by the fixing means (180 in FIG. 3) or is passed through by the second fixing means 157 to be fastened, in order to reduce the material cost.

The first polarizing plate 118 has a lamination structure of a base film, a TAC, a polarizing layer, a TAC, and a pressure sensitive adhesive layer. The first polarizing plate 118 having such a structure is formed of an auxiliary film 190 (polyethylene terephthalate) ) Is several times more expensive. Therefore, when the first polarizing plate 118 is fixed to the lower portion of the cover bottom 150, the material cost is increased.

However, when the increase in the material ratio is not taken into consideration in the display devices (101 in FIG. 3 and 201 in FIG. 7) according to the first and second embodiments of the present invention having such a configuration, The first polarizing plate 118 itself is used to fix the bracket (184 in Fig. 3, 284 in Fig. 7) and the cover (not shown) to the left and right ends of the first polarizing plate 118, And may be fixed by the second fastening means 157 between the bottoms 150.

In the display device according to the first and second embodiments of the present invention (101 in FIG. 3 and 201 in FIG. 7), an auxiliary film 190 is attached to the left and right ends of the first polarizing plate 118, The polarizing plate 118 and the auxiliary film 190 are wrapped around the left and right ends of the side panel 130 and positioned on the lower surface of the cover bottom 150, Is fastened and fixed by the second fastening means 157 via a bracket (184 in Fig. 3, 284 in Fig.

8 (a sectional view of a portion of a display device according to a modified example of the first embodiment of the present invention, in which a light source is not formed and a predetermined width is cut at one end of one of the left and right sides) And FIG. 9 (a cross-sectional view of a portion of a display device according to a modification of the second embodiment of the present invention in which a light source is not formed at a predetermined width at one end of one of the left and right ends) The extension portion EA of the first polarizing plate 118 itself does not include the film 190 (FIGS. 3 and 7) and the left and right ends of the guide panel 130 are wrapsped, , 284 of FIG. 9), and is fixed to the lower surface of the cover bottom 150 by the second fastening means 157. [

In the case of the display device (102 in FIG. 8 and 202 in FIG. 9) according to the modification of the first and second embodiments of the present invention, the auxiliary film (190 in FIGS. 3 and 7) is omitted, 3 and FIG. 7) is provided in the extended portion EA of the first polarizing plate.

In the display device according to the modification example of the first and second embodiments of the present invention (102 in FIG. 8 and 202 in FIG. 9), the extended portion EA of the first polarizing plate itself is fixed to the second fastening means 157, The display device according to the first and second embodiments of the present invention (101, Fig. 3, Fig. 3, Fig. 3, Fig. 7, 201). Therefore, the description of the constitution will be omitted.
