no. 1 Embodiment approach
[0081] FIG. 1 is a plan view of an electro-optical device 100 according to the present embodiment. FIG. 2 is a sectional view of the electro-optical device 100 taken along line A-A' in FIG. 1 . FIG. 3 is an exploded perspective view of the electro-optical device 100 .
[0082] In FIGS. 1 and 2 , an electro-optical device 100 has a liquid crystal device 60 , a case 110 , a hook 130 , and a flexible printed wiring board 120 .
[0083] In FIG. 2 , the outer peripheral portion of the liquid crystal device 60 is sandwiched by the case 110 and the hook 130 . A filling material 19 is filled between the liquid crystal device 60 and the case 110 . In addition, the flexible printed circuit board 120 is connected to the liquid crystal device 60 and drawn out from the case 110 .
[0084] In FIG. 2 , incident light 200 enters from above with respect to the paper surface, and is emitted downward as outgoing light 300 . In contrast, in FIG. 3 , incident light 200 is incident from below t...
no. 2 Embodiment approach
[0127] Fig. 10(a) is a plan view of the light incident side dustproof glass 20 of this embodiment, and Fig. 10(b) is a cross-sectional view taken along line D-D' of Fig. 10(a). FIG. 11 is a partial enlarged view of the reflective film 121 and the vicinity of the notch 14 .
[0128] This embodiment differs from the first embodiment in that the black layer 15 which is a light absorbing layer is provided on the surface of the cutout surface 140 .
[0129] Black layer 15 can use toner ( Coating り) or carbon black dispersed material. For example, CK-7800L manufactured by Fujifilm Electronic Materials Co., Ltd. or the like can be used.
[0130] Hereinafter, effects of the present embodiment will be described.
[0131] (8) Not only the reflection of the return light 400 is controlled by the notch 14 but also the return light 400 is absorbed by the black layer 15 , so the reflectance of the notch 14 can be reduced. Therefore, the light reflected by the cutout portion 14 and direc...
no. 3 Embodiment approach
[0133] Fig. 12(a) is a plan view of the light-incident side dustproof glass 30 of this embodiment, and Fig. 12(b) is a cross-sectional view along line E-E' of Fig. 12(a). FIG. 13 is a partial enlarged view of the reflective film 121 and the vicinity of the notch 16 .
[0134] In FIG. 13 , this embodiment differs from the first embodiment in that the notch 16 is concave. The notch portion 16 can be formed by changing the shape of the cutting blade. Here, regarding the shape of the concave surface of the notch portion 16, the light incident surface 7 of the dustproof glass 30 on the light incident side intersects approximately at right angles, and the length of the normal line intersecting the notch surface 160 increases from the light exit surface 6 to the end surface. 8 and become shorter. The surface of the notch surface 160 may be a rough surface or a smooth surface.
[0135] Hereinafter, effects of the present embodiment will be described.
[0136] (9) The notch surface...
