Thin film transistor array panel and manufacturing method thereof

摘要

A method of manufacturing a thin film transistor array panel is provided, which includes: forming a gate line on a substrate; depositing a first insulating layer and a semiconductor layer in sequence on the gate line; depositing a conductive layer on the semiconductor layer; photo-etching the conductive layer and the semiconductor layer; depositing a second insulating layer; photo-etching the second insulating layer to expose first and second portions of the conductive layer; forming a pixel electrode on the first portion of the conductive layer; removing the second portion of the conductive layer to expose a portion of the semiconductor layer; and forming a light blocking member on the exposed portion of the semiconductor layer, the light blocking member having an opening exposing the pixel electrode.
