Abstract:
1. A method of manufacturing a thin film transistor display panel, comprising: depositing a first insulation material including a light blocking material on a substrate; depositing a semiconductor material on the first insulation material; depositing a second insulation mate al on the semiconductor material; forming a first photosensitive film pattern on the second insulation material; patterning the second insulation material using the first photosensitive film pattern; forming a semiconductor layer by patterning the semiconductor material using the first photosensitive film pattern; removing the first photosensitive film pattern; depositing a gate metal material on the second insulation material; forming a second photosensitive film pattern on the gate metal material; forming a gate electrode by patterning the gate metal material using the second photosensitive film pattern; and forming a first insulating layer and a second insulating layer by substantially simultaneously patterning the first insulation material and the second insulation material using the second photosensitive film pattern.
