LIQUID CRYSTAL DISPLAY DEVICE AND ITS PRODUCTION

摘要

PROBLEM TO BE SOLVED: To produce a reflection type liquid crystal display device in the same production process as a transmission type liquid crystal display device. SOLUTION: A mask for photolithography capable of forming both a gate electrode 22 and a reflecting plate 23 and a mask for photolithography capable of forming only the gate electrode 22 are prepared, and a reflection type liquid crystal display device with both the gate electrode 22 and the reflecting plate 23 formed on a transparent insulating substrate 21 or a transmission type liquid crystal display device with only the gate electrode 22 formed on the transparent insulating substrate 21 is selectively produced by using one of the masks.
