Abstract:
1. A method of fabricating a liquid crystal display having a thin film transistor with a gate electrode, a gate insulating film, an active layer, an ohmic contact layer, a source electrode, and a drain electrode on a transparent substrate, said method comprising: forming an organic passivation layer over the transparent substrate and over the thin film transistor; defining a contact hole through the organic passivation layer to expose the drain electrode; irradiating the organic passivation layer with ultraviolet rays having a wavelength in a range between about 100 nm and about 200 nm to form a hydrophilic buffer layer having a thickness of 10 Å to 50 Å; and forming a pixel electrode over the hydrophilic buffer layer and in the contact hole such that the pixel electrode contacts the drain electrode via the contact hole and such that the pixel electrode adheres to the hydrophilic buffer layer.
