Title:
LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
Japanese Patent JP2018159938
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a liquid crystal display device with high display quality by preventing irradiation of a semiconductor layer with light diffracted at an end of a light-blocking layer which causes variation in thin film transistor (TFT) characteristics.SOLUTION: In order to completely block light 117 diffracted at an end of a third light-blocking layer 108, a semiconductor layer 103 is covered with a gate electrode 104 and second light-blocking portions 106. Thus, irradiation with diffracted light can be prevented, variation in TFT characteristics can be avoided, and an excellent display image can be obtained.SELECTED DRAWING: Figure 1
