Liquid crystal device and electronic apparatus
View Patent ↗A liquid crystal device includes adjacent sub pixels with adjacent reflection regions and adjacent transmission regions. The device also includes a liquid crystal layer thickness adjusting layer that is continuously formed between two of the sub pixels and provided at least in reflection region. The liquid crystal layer thickness adjusting layer is disposed between the first sub pixel and the second sub pixel having a groove extending from the transmission region and along a boundary between the first and second sub pixels. The color filter for the first sub pixel transmits a color light having the lowest visibility corresponds. Further, a spacer is optionally disposed on an extension line of the groove or at a location adjacent to the groove.
1. A liquid crystal device comprising:
a pair of substrates;
a liquid crystal layer interposed between the pair of substrates;
a first region and a second region, a thickness of the liquid crystal layer being smaller in the second region than that in the first region;
a plurality of sub pixels, each of the sub pixels having a transmission region formed in the first region and a reflection region formed in the second region, the transmission regions of the plurality of sub pixels arranged side-by-side, and the reflections regions of the plurality of sub pixels arranged side-by-side;
a plurality of color filters including a first color filter, a second color filter and a third color filter, the first, the second and the third color filters corresponding to each of the sub pixels, respectively; and
a liquid crystal layer thickness adjusting layer placed at least in the second region, the liquid crystal layer thickness adjusting layer having a groove formed at a boundary between sub pixels corresponding to the first color filter and the second color filter, the liquid crystal layer thickness adjusting layer not having a groove and continuously formed between sub pixels corresponding to the second and the third color filters,
wherein a light transmitted by the first color filter has lower visibility than lights transmitted by the second and the third color filters and a light transmitted by the third color filter has higher visibility than lights transmitted the first and the second color filters.
2. A liquid crystal device according to claim 1 ,
wherein the plurality of color filters includes a color filter that transmits a blue light, a color filter that transmits a red light, and a color filter that transmits a green light, and
wherein the first color filter transmits the blue light, the second color filter transmits the red light and the third color filter transmits the green light.
3. A liquid crystal device according to claim 1 ,
wherein one of the pair of substrates has the plurality of color filters, and the other of the pair of substrates has the liquid crystal layer thickness adjusting layer.
4. The liquid crystal device according to claim 1 , the device further comprising
a spacer which holds a gap between the pair of substrates,
wherein the spacer is disposed in a region of the first color filter.
