Abstract
A liquid crystal display with in-plane switching mode for improving its light transmittance, includes a first substrate that forms light transmissive portions and light untransmissive portions, a second substrate, and liquid crystal injected between the first and second substrates. The second substrate includes a black matrix, a color filter layer, an overcoat layer and an alignment film. The overcoat layer is patterned to form micro-lenses for refracting the incident light to pass through the light transmissive portions without being blocked by the light untransmissive portions. Various patterning methods can be selected to form the micro-lenses.
Claims27
A liquid crystal display device comprising:
- a first substrate including pixel electrodes, counter electodes, and regions between the pixel electrodes, and counter electrodes, the pixel and counter electrodes including light transmissive portions, the regions including light transmissive portions;
- a second substrate;
- a liquid crystal between the first and second substrates and
- a focusing layer formed on the second substrate for focusing a light passing through the focusing layer onto said light transmissive portions and away from said light untransmissive portions.
A method of operating a liquid crystal display device including a first substrate having pixel electrodes, counter electrodes, and regions between the pixel electrodes and counter electrodes;
- a second substrate;
- and a liquid crystal between the first and second substrates, wherein the pixel and counter electrodes include light untransmissive portions and the regions include light transmissive portions, the method comprising the steps of:
- generating a light using a light source set behind the second substrate;
- and
- focusing the light passing tough the second substrate onto said light transmissive portions of the first substrate and away from said light untransmissive portions.
