no. 1 Embodiment approach
[0081] figure 1 It is a plan view of the electro-optical device 100 according to this embodiment. figure 2 is an electro-optical device 100 of figure 1 A-A' profile in . image 3 is an exploded perspective view of the electro-optical device 100 .
[0082] exist figure 1 with figure 2 Among them, the electro-optical device 100 has a liquid crystal device 60 , a housing 110 , a hook 130 , and a flexible printed wiring board 120 .
[0083] exist figure 2 Among them, the outer peripheral portion of the liquid crystal device 60 is clamped 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] exist figure 2 In the drawing, incident light 200 enters from above with respect to the paper surface, and exits as outgoing light 300 downward. Instead, in image 3 In ,...
no. 2 Embodiment approach
[0127] Figure 10 (a) is a plan view of the light incident side dustproof glass 20 of this embodiment, Figure 10 (b) is Figure 10 (a) Cross-sectional view at D-D'. Figure 11 It 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] For the black layer 15 , a material obtained by dispersing toner or carbon black can be used. 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 ...
no. 3 Embodiment approach
[0133] Figure 12 (a) is a top view of the light incident side dustproof glass 30 of this embodiment, Figure 12 (b) is Figure 12 Sectional view at E-E' of (a). Figure 13 It is a partial enlarged view of the reflective film 121 and the vicinity of the notch 16 .
[0134] exist Figure 13 Among them, the present 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, it crosses the light incident surface 7 of the light incident side dustproof glass 30 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.
