Title: THIN-FILM TRANSISTOR, ARRAY SUBSTRATE AND DISPLAY DEVICE
Abstract:
A thin-film transistor, an array substrate comprising same, and a display device. The thin-film transistor comprises a gate electrode (100), a gate insulating layer (200), an active layer (300) and a source/drain electrode layer (400) which are stacked in sequence. The source/drain electrode layer (400) comprises a source electrode (401) and a drain electrode (402), there is a space between the source electrode (401) and the drain electrode (402), and the active layer (300) forms a channel (301) in a region corresponding to the space. At least one side of the gate electrode (100) in the channel (301) in the width direction thereof is provided with a gate electrode projection (101), and the gate insulating layer (200) covers the gate electrode (100) and the gate electrode projection (101).
