Electro-optical device and electronic equipment
View Patent ↗An electro-optical devices includes: a first substrate; a second substrate having one surface opposite to the first substrate; a support member configured to hold the first and second substrates with the second substrate located outside the first substrate, and to include a frame portion surrounding the first and second substrates; a first conductive film formed on the other surface of the second substrate; and a conductor layer placed between the frame portion and the first and second substrates, and electrically connected to the first conductive film. The first conductive film is held at a constant potential via the conductor layer.
1. An electro-optical device comprising:
an illumination unit that includes a light guide plate, a light source provided along an end portion of the light guide plate, and an optical sheet overlapping the light guide plate;
a panel that is provided on a side of the optical sheet of the illumination unit and includes a first substrate facing the optical sheet, a second substrate facing the first substrate, and an electro-optical material between the first substrate and the second substrate;
a support member that includes a frame portion and a step portion, the frame portion surrounding the panel and the illumination unit, the step portion being formed on an inner side of the frame portion and having an upper surface for holding the first substrate;
an upper polarizing plate provided on a surface of the second substrate opposite to a surface facing the first substrate;
a tape provided between the first substrate and the optical sheet, one surface of the tape being bonded to a surface of the first substrate opposite to a surface facing the second substrate, the other surface of the tape being bonded to the upper surface of the step portion; and
a light-shielding sheet having a first area contacting an end of the light guide plate,
wherein the light-shielding sheet includes a second area that is stacked between an end portion of the optical sheet and the panel.
2. The electro-optical device according to claim 1 , wherein
the first substrate includes an outer edge portion extending outside an outer edge of the optical sheet and an outer edge of the light guide plate,
the upper surface of the step portion holds the outer edge portion of the first substrate,
the tape is provided along the outer edge portion of the first substrate, and
the one surface of the tape is bonded to the outer edge portion of the first substrate.
3. The electro-optical device according to claim 1 , further comprising a lower polarizing plate between the optical sheet and the first substrate, wherein
the tape is formed outside an outer edge of the lower polarizing plate.
