Abstract
A liquid crystal display which has spacers reliably joined with a pair of substrates of the liquid crystal display by using spacers adapted to the purpose with respect to material, structure, method of joining with the substrates, etc. A pair of substrates can be reliably joined with spacers, and the strength of the liquid crystal display against an external pressure as well as display characteristics can be thereby improved. A manufacturing methods for such a liquid crystal display is also disclosed.
Claims9
A liquid crystal display comprising:
- a pair of substrates;
- liquid crystal sealed between said substrates;
- a sealant for sealing an outer periphery of said substrates;
- and a multiplicity of spacers disposed between said substrates, and in an area defined by the pair of substrates and the sealant, for maintaining the substrate gap, wherein said spacers are cylindrical in shape as patterned by photolithography, wherein each spacer is adhered to said substrates at both ends of the cylinder and in an area other than outer peripheries of the substrates, and consists of a plurality of resin layers of different elastic moduli, and wherein the plurality of resin layers includes, in order, a hard resin layer, a soft resin layer, and a hard resin layer, and the hard resin layers are adhered to the substrates.
