发明名称 Method for manufacturing thin film transistor substrate using maskless exposing device
摘要 A method for manufacturing a thin film transistor substrate using a maskless exposing device includes forming a data metal layer on a substrate having a gate pattern and common electrodes along with gate insulation layers, active layers, and ohmic contact layers for a thin film transistors; forming a photoresist on the data metal layer; exposing a first amount of light onto the photoresist at first regions, excluding a second region where data lines and thin film transistors are to be formed, by using a maskless exposing device; exposing a second amount of light onto the photoresist at third regions, where channels of the thin film transistors are to be formed, wherein the second amount of light is smaller than the first amount of light; and developing the first, second and third regions of the photoresist.
