Abstract:
An in-plane switching type liquid crystal display comprising:(a) a first transparent substrate;(b) a pixel electrode and a common electrode both formed on an upper surface of said first transparent substrate so that they are spaced away from each other;(c) a second transparent substrate spaced away from said first transparent substrate in parallel;(d) a color filter formed on said second transparent substrate so that said color filter faces said upper surface of said first transparent substrate;(e) a liquid crystal layer sandwiched between said first and second transparent substrates;(f) a pair of polarizing plates sandwiching said first and second transparent substrates therebetween;(g) a back-light source for emitting a back-light through a lower surface of said first transparent substrate; and(h) a chromaticity controller for determining chromaticity of said back-light in accordance with chromaticity variation in display nonuniformity caused by a dispersion in a distance between said first and second transparent substrates, to thereby nearly equalize said chromaticity of said back-light to chromaticity in said display nonuniformity for rendering said display nonuniformity inconspicuous.
