Liquid crystal display device including an auxiliary capacitance line with a branch portion

摘要

A liquid crystal display device, including: an array substrate including: a first pixel electrode, first and second source lines arranged in a first direction and extending in a second crossing direction, a first gate line, an auxiliary capacitance line, a second gate line arranged in the second direction and extending in the first direction, and a switching element including a semiconductor layer which includes a first portion overlapping the first source line and extending in the second direction and a second portion overlapping the auxiliary capacitance line and extending in the first direction. The auxiliary capacitance line includes a branch portion extending along the first source line toward the second gate line and formed on a layer between the first source line and the semiconductor layer. The array substrate includes first and second shield layers, and the first shield layer formed larger than the second shield layer.
