US 2017/0363890 A1 · LIQUID CRYSTAL DISPLAY DEVICE

Abstract

The present invention provides a liquid crystal display device in which display unevenness is suppressed by preventing degradation of TFT characteristics due to photo-alignment treatment. The liquid crystal display device of the present invention is a liquid crystal display device including: a thin-film transistor substrate; and a liquid crystal layer, the thin-film transistor substrate including a thin-film transistor having a channel etch structure and an alignment film, the thin-film transistor including a gate electrode, a gate insulating film, a channel layer containing an oxide semiconductor, and a pair of a source electrode and a drain electrode in the stated order, the oxide semiconductor containing indium, tin, zinc, and oxygen, the alignment film having a photofunctional group.
