Thin film transistor array panel and method of manufacturing the same

摘要

In one embodiment, a thin film transistor array display panel and method of manufacturing the same are provided. A method includes forming a gate line on a substrate; forming a gate insulating layer, a semiconductor layer, and an ohmic contact layer on the gate line; forming a data layer on the ohmic contact layer; forming a photosensitive pattern on the data layer; etching the data layer to form a data line including a source electrode and a drain electrode that is opposite to the source electrode; reflowing the photosensitive pattern to cover side surfaces of the source electrode and the drain electrode; and etching the ohmic contact layer using the reflowed photosensitive pattern as a mask.
