Title: Liquid crystal display device
Inventor: NORITAKE KAZUTO
IPC: G02F1/1368
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To prevent the unequal luminance by the variation in a retardation quantity of a liquid crystal display device of a type integrated with driving circuits for which p-SiTFTs (thin-film transistors) are used by making the cell gap of the device uniform. SOLUTION: Trapezoidal films 17PLG consisting of the same metallic films as drain source electrodes are arrayed and formed between gate lines 13L of a sealant forming region. Sealants are formed on the regions where the trapezoidal films 17PLG are arrayed and second interlayer insulating films consisting of flattening films are formed at a uniform film thickness. The difference between the grain size of the spacers incorporated into the sealants and the grain size of the spacers sprayed to pixel parts is set the same as the difference in the thicknesses of the sealant forming regions and the second interlayer insulating films deposited on the pixel parts, by which the cell gap is made uniform.

Abstract: PROBLEM TO BE SOLVED: To increase the output of illuminating light without lowering the utilization efficiency of light from an illumination optical system even in the case of using a large-output light source lamp by reducing the bundle of rays made incident on a polarized light converting optical system in size in a specified direction by a variable power relay optical system. SOLUTION: The bundle of rays made incident on the polarized light converting optical system is reduced in the size in the specified direction by the variable power relay optical system. In this illumination optical system, a 1st small lens 32a and a 2nd small lens 34a which are paired are arranged at the conjugate point of a relay lens 36a. Then, the variable power relay optical system has a function to reduce the width D1 of the bundle of rays made incident on the lens 32a at the ratio of a distance L2 to a distance L1, that is, a reduction ratio L2/L1. By setting the distance L2 to 1/2 of the distance L1, for example, the width D2 of the bundle of rays emitted from the lens 34a is made nearly equal to 1/2 of the width D1 of the bundle of rays made incident on the lens 32a by the variable power relay optical system.
