Title:
LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
Japanese Patent JP3323880
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve a display quality and a good producer rate of a liquid crystal display device for which a high numerical aperture is achieved via an interlayer insulating film.
SOLUTION: A split area of a picture element electrode 15 is provided on a shading pattern 16 branched from a gate wiring 2 on an insulating substrate like glass and an auxiliary wiring 3. A source wiring 8 is comprised of a transparent conductive film and is provided under the picture element electrode 15 via an interlayer insulating film. Thus, it is possible to obtain a uniform superimposed width between the source wiring and the picture element 15, and this arrangement can eliminate faulty display called block separation occurring in stepper method. Further, since it is possible to hide light leakage between picture elements 15 by the shading pattern 16, shading film does not need to be provided at the side of the counter substrate, and it is possible to improve the numerical aperture by a margin considering a misregistration at the time of sticking the counter substrate to an active matrix substrate.
