Electro-optic device and electronic apparatus
View Patent ↗An electro-optic device includes a frame, an optical member including a light guide plate accommodated within the flame, an illuminator, and a display panel disposed over the optical member. The display panel includes a substrate that has a light-shielding black mask extending in the shape of a picture frame along edges of the substrate. The black mask partially has at least one light-shielding extended segment extended toward at least one of the edges of the substrate.
1. An electro-optic device comprising:
a frame;
an optical member including a light guide plate accommodated within the frame;
an illuminator; and
a display panel disposed over the optical member,
wherein the display panel includes a substrate that has a light-shielding black mask extending in the shape of a picture frame along edges of the substrate;
the black mask partially has at least one light-shielding extended segment extended toward at least one of the edges of the substrates;
the optical member has a projection that projects outward from an outer periphery of the optical member; and
wherein the at least one light-shielding extended segment of the black mask is provided such that the projection and the at least one light-shielding extended segment positionally coincide with each other.
2. The electro-optic device according to claim 1 , wherein the at least one light-shielding extended segment is rectangular in plan view.
3. The electro-optic device according to claim 1 , wherein the at least one light-shielding extended segment includes a plurality of light-shielding extended segments provided at multiple locations of the black mask.
4. The electro-optic device according to claim 1 , wherein an edge of the at least one light-shielding extended segment and the at least one of the edges of the substrate are spaced apart from each other by a distance that is within a range of 0.01 to 0.1 mm.
5. The electro-optic device according to claim 1 , wherein an edge of the black mask at a location where the at least one light-shielding extended segment is not provided and the at least one of the edges of the substrate are spaced apart from each other by a distance that is within a range of 0.2 to 0.5 mm.
6. The electro-optic device according to claim 1 , further comprising a bezel that covers the frame, the optical member, the illuminator, and the display panel, the bezel having a window corresponding to a display region of the display panel and an opening corresponding to a region other than the display region of the display panel,
wherein the at least one light-shielding extended segment of the black mask is provided such that the opening of the bezel and the at least one light-shielding extended segment positionally coincide with each other.
7. An electronic apparatus comprising the electro-optic device according to claim 1 .
8. The electro-optical device according to claim 1 , wherein the optical member has a projection that is extending outwardly from an outer periphery of the optical member, the frame has a recess that is formed at an inner periphery of the frame and corresponding to the projection, and an extended segment of the light-shielding black mask is disposed in a position where the projection and the recess overlap in plan view.
