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 with two opposing substrates sandwiching therebetween a liquid crystal layer variable in thickness either within a single pixel or from one pixel to another, wherein
- there are provided columnar spacers between the two substrates where the liquid crystal layer is thinnest, the columnar spacers being elongated in a direction connecting the two substrates to maintain a cell gap.
A manufacturing method of a liquid crystal display, comprising the steps of:
- providing a transparent electrode on a substrate to drive liquid crystal;
- providing columnar spacers on the transparent electrode;
- and
- providing an alignment layer on the entire substrate.
A manufacturing method of a liquid crystal display, comprising the steps of:
- providing a transparent electrode on a substrate to drive liquid crystal;
- providing an alignment layer on the transparent electrode;
- rubbing the alignment layer;
- and
- providing columnar spacers on the rubbed alignment layer.
A manufacturing method of a liquid crystal display, comprising the steps of:
- providing a black matrix layer on a substrate;
- providing a color filter layer;
- providing apertures on the black matrix layer;
- and
- providing columnar spacers in the apertures, using the apertures as a mask.
