Abstract

See full text

A method of fabricating a liquid crystal panel comprises the steps of forming a black matrix on a substrate, forming a buffer layer on the substrate, forming semiconductors layer on the buffer layer, doping n.sup.+ impurities into a semiconductor layer on a pixel region on the substrate and in one semiconductor layer of the driver circuit region forming a gate insulating layer on the buffer layer and the semiconductor layer, forming a gate electrode on the gate electrode, introducing n.sup.-impurities into the semiconductor layer using the gate electrode as a mask after patterning of the gate insulating layer, doping p.sup.+ impurities into another semiconductor layer of the driver circuit unit, forming an insulating layer having a contact hole over the pixel region, forming a transparent electrode on the pixel region and into the contact hole.
