Liquid crystal device and electronic apparatus
View Patent ↗Aspects of the invention provide a transflective liquid crystal display device that prevents display failure, such as an afterimage and unevenness like stains, and achieves a bright display with a wide viewing angle in both transmissive display and reflective display. The liquid crystal display device of the invention is a vertically-aligned transflective liquid crystal display device having a multigap structure. Each pixel can include, in a dot region, a plurality of islands, and connecting portions for electrically connecting the adjoining islands. Two islands, of the islands, can be disposed in a transmissive display region, and the remaining island is disposed in a reflective display region. A boundary sloping area in which the thickness of a liquid crystal layer continuously changes is disposed right below the connecting portion in the pixel electrode.
1. A liquid crystal display device, comprising:
a pair of substrates having a dot region;
a liquid crystal layer disposed between the pair of substrates and containing liquid crystal that has a negative anisotropy;
a transmissive display region and a reflective display region provided in the dot region;
a pixel electrode provided in the dot region, the pixel electrode having a plurality of islands and a connecting portion that electrically couples adjoining islands, the islands including an integral number of islands in each of the transmissive display region and the reflective display region; and
a signal line extending along an edge of the pixel electrode,
a distance between the pixel electrode and the signal line in the reflective display region being shorter than a distance between the pixel electrode and the signal line in the transmissive display region.
2. The liquid crystal display device according to claim 1 , the islands having almost a same planar shape in the reflective display region and the transmissive display region.
3. The liquid crystal display device according to claim 1 , an alignment control device being provided in planar regions of the islands to control an alignment state of the liquid crystal when a voltage is applied.
4. The liquid crystal display device according to claim 3 , the alignment control device being provided corresponding to the islands in the dot region, and an alignment control device corresponding to an island disposed in the reflective display region having a planar area smaller than that of an alignment control device disposed in the transmissive display region.
5. The liquid crystal display device according to claim 1 , an island disposed in the reflective display region having a planar area larger than that of an island disposed in the transmissive display region.
6. An electronic apparatus, comprising the liquid crystal display device according to claim 1 .
