    • A thin film transistor display panel includes gate wiring formed on an insulation substrate and including gate lines, and gate electrodes and gate pads connected to the gate lines; a gate insulation layer covering the gate wiring; a semiconductor pattern formed over the gate insulation layer; data wiring formed over the gate insulation layer or the semiconductor pattern and including source electrodes, drain electrodes, and data pads; a protection layer including a Nega-PR type of organic insulating layer formed all over the semiconductor pattern and the data wiring, wherein the thickness of the Nega-PR type of organic insulating layer in both the gate and data pad regions is smaller than in the other regions; and a pixel electrode connected to the drain electrode. When exposing the Nega-PR type of passivation layer in the pad region during a photolithography process, a photomask having a lattice pattern made of a metal such as Cr that has a line width of less than the resolution of a light exposer is used. Thus, the resulting post-etch height of the passivation layer can be selectively controlled so as to provide reduced effective thickness in the pad regions.
