Abstract
An imaging device having a lens, an optical sensor and an aperture placed close to the lens, the aperture is constituted by a liquid crystal aperture, which has a first substrate, a second substrate and a liquid crystal layer therebetween; a lower layer electrode, an interlayer insulating layer, and an upper layer electrode are formed in this order on the first substrate; the upper layer electrode having a first electrode, which is formed in an area which includes a center of the pattern area, and a second electrode disposed from the first electrode with a space, a columnar spacer is formed between the first electrode and the second substrate in a plan view.
Claims12
An imaging device having a lens, an optical sensor that receives light, and an aperture placed close to the lens and placed between the lens and an object to be imaged,
- the aperture being constituted by a liquid crystal aperture in which a liquid crystal layer is sandwiched between a first substrate and a second substrate, a pattern area, and a peripheral light shielding frame,
- a lower layer electrode, an interlayer insulating layer, and an upper layer electrode being formed in this order on the first substrate,
- the upper layer electrode having a first electrode, which is formed in an area which includes a center of the pattern area, and a second electrode disposed from the first electrode with a space,
- wherein the space and the lower layer electrode overlap in a plan view,
- a first light shielding film constituting the peripheral light shielding frame is formed in a periphery of the second substrate, and a first columnar spacer is formed between the first light shielding film and the first substrate in a plan view,
- a second columnar spacer is formed between the first electrode and the second substrate in a plan view.
An imaging device having a lens, an optical sensor that receives light, and an aperture placed close to the lens and placed between the lens and an object to be imaged,
- an outer shape of the aperture being rectangular,
- the aperture being constituted by a liquid crystal aperture in which a liquid crystal layer is sandwiched between a first substrate and a second substrate, a pattern area, and a peripheral light shielding frame,
- wherein the pattern area is a pentagon or larger polygon or circle,
- in the pattern area, scanning lines extend in a first direction and are arranged in a second direction, video signal lines extend in the second direction and are arranged in the first direction, a pixel is formed in a region surrounded by the scanning lines and the video signal lines, a pitch of the pixel in the first direction is 30 μm or less, and a pitch of the pixel in the second direction is 30 μm or less,
- in the pattern area, a columnar spacer, which determines a distance between the first substrate and the second substrate, is formed in a first area which includes a center of the pattern area, and
- in the first direction, a width of the first area is 30% or less of a width of the pattern area.
