Abstract:
1. A manufacturing method of a display panel comprising: forming a gate electrode on a substrate; forming a gate insulating layer on the gate electrode; sequentially depositing a first material layer, a second material layer, and a third material layer on the gate insulating layer; etching the third material layer, the second material layer, and the first material layer to form a data conductor, an extrinsic semiconductor, and an intrinsic semiconductor; etching the data conductor to form a source electrode and a drain electrode and simultaneously exposing a first portion of the extrinsic semiconductor; plasma-treating the first portion of the extrinsic semiconductor between the source electrode and the drain electrode, the first portion comprising a protection member and respective sides of the protection member comprising ohmic contacts; forming a color filter on the source electrode, the drain electrode, and the protection member; and forming a pixel electrode connected to the drain electrode on the color filter, wherein the etching of the third material layer, the second material layer, and the first material layer, the etching of the data conductor, and the plasma-treatment of the extrinsic semiconductor are sequentially executed in the same plasma generation apparatus.
