As shown in the figure, the upper portion of the antiglare filter 6 is fixed to the opening of the housing 1 by the fixing bolts 5, the holding pawls 7a and 7b are fixed to the housing 1, and the side portions and the lower portion of the antiglare filter 6 are held. The antiglare filter 6 is held by 7a and 7b.
A gap larger than the maximum expansion amount of the anti-glare filter 6 is provided between the side and lower end surfaces 6a of the anti-glare filter 6 and the holding pawls 7a and 7b.
A gap is provided between the side and the bottom of the anti-glare filter 6 so that the anti-glare filter 6 and 7b can move.

Even if the antiglare filter 6 thermally expands due to heat generated from the antiglare filter 6, a gap is provided between the side portion and the lower end surface 6a of the antiglare filter 6 and the holding pawls 7a and 7b. Since the gap is provided between the back surface 6b of the lower portion and the holding pawls 7a and 7b, the side portion and the lower portion of the antiglare filter 6 can freely move, so that the antiglare filter 6 warps and distorts. Therefore, the visibility of the display is good. Further, since it is not necessary to use an antiglare filter made of tempered glass having a small coefficient of thermal expansion, the manufacturing cost does not increase, the efficiency of the assembling work does not decrease, and the apparatus becomes lightweight.
