Abstract:
1. A display device, comprising: a substrate; a thin film transistor on the substrate; and a passivation layer of a photosensitive organic material on the thin film transistor, the passivation layer having a contact hole exposing the thin film transistor, wherein the photosensitive organic material comprises an ultraviolet (UV) absorber, a photoinitiator, and a crosslinker, the UV absorber is configured to absorb reflected UV rays passing by a blocking area in a mask above the contact hole, and the crosslinker links a free radical generated by the photoinitiator when UV rays are irradiated, wherein the crosslinker includes a multifunctional monomer, wherein a critical exposure energy density of the photosensitive organic material is adjusted by an acid value of the multifunctional monomer, and wherein the UV absorber has an extinction coefficient of (214.3˜551.5)×10
