Abstract
A liquid crystal display has spacers for maintaining a liquid crystal layer and a cell gap between a substrate and an opposite substrate and also has regions either within a single pixel or over two or more pixels. The spacers are of columnar shape elongated from the substrate to the opposite substrate or the other way round, and the columnar spacers are provided in regions in which the liquid crystal layer is thinnest among those regions in which the liquid crystal layer varies in thickness. The structure makes the liquid crystal display having two or more different cell gaps to stably maintain those cell gaps and produces good quality displays.
Claims14
A liquid crystal display, comprising:
- a first substrate;
- a second substrate;
- a liquid crystal layer between the first and second substrates;
- a plurality of pixel electrodes on the second substrate,
- each of pixel electrodes having (i) a reflection section for performing the reflection-mode display by using light incident on the first substrate and (ii) a transmission section for performing transmissive-mode display by using light incident on the second substrate;
- a color filter on the first substrate;
- a transparent electrode on the color filter;
- and
- columnar spacers at predetermined locations on the transparent electrode,
- the first and second substrates being disposed opposite each other so that the columnar spacers are positioned in the reflection sections, and
- the reflection section including an interlayer insulation layer so that the liquid crystal layer is thinner in the reflection section than in the transmission section.
