Patent ID: RE40601

Claim:
A method of manufacturing an active matrix substrate comprising a pixel portion including thin film transistors connected to scanning lines and signal lines arranged in a matrix, and pixel electrodes connected to terminals of the thin film transistors, the method comprising the steps of: forming a separation layer on a substrate; forming the thin film transistors over the separation layer; forming an insulation film on the thin film transistors and over the separation layer; selectively removing at least a portion of the insulation film where each of the pixel electrodes is to be formed; forming each of the pixel electrodes on the insulation film and the separation layer in the region where at least a portion of the insulation film has been removed; adhering the thin film transistors to a transfer material with an adhesive layer; producing exfoliation in the separation layer and/or at an interface of the separation layer and the substrate to separate the substrate from the separation layer; and removing any portion of the separation layer remaining on the pixel electrodes to form an active matrix substrate using the transfer material as a new substrate.
