LIQUID CRYSTAL DISPLAY DEVICE AND MANUFACTURING METHOD THEREOF

摘要

A liquid crystal display device includes a substrate; a gate electrode on the substrate; a semiconductor pattern layer on the gate electrode; and source and drain electrodes on the semiconductor pattern layer and spaced apart from each other. The source electrode includes: a first facing portion facing the drain electrode; and a first protrusion protruding toward the drain electrode from the first protrusion. The drain electrode includes: a second facing portion facing the source electrode; and a second protrusion protruding toward the source electrode from the second facing portion and facing the first protrusion. The semiconductor pattern layer includes: a source area overlapping the source electrode; a drain area overlapping the drain electrode; and a bridge area connecting the source area with the drain area, and a space defined between the first protrusion and the second protrusion is on the bridge area.
