Abstract:
1. A fabricating method for a thin film transistor substrate, comprising: forming a gate wire on an insulating substrate; forming a data wire crossed with the gate wire and defining a pixel area; forming a thin film transistor on the intersection of the gate wire and the data wire; forming an inorganic insulating layer covering the thin film transistor; forming an organic photosensitive layer on the inorganic insulating layer; disposing a mask for the diffraction exposure over the organic photosensitive layer; forming a photosensitive layer pattern by exposing the organic photosensitive layer to light through the mask and developing the organic photosensitive layer; forming a prominence and depression pattern at inorganic insulating layer by etching the inorganic insulating layer through the photosensitive layer pattern; and forming a reflective layer on the prominence and depression pattern of the inorganic insulating layer, wherein the mask includes a blocking part, a semi-transmitting part having a plurality of slit parts and a transmitting part, the ratio of the width of the blocking part to the width of the semi-transmitting part is 3:4, and the gap between the slits is different at both sides of the center of the semi-transmitting part.
