Abstract:
1. A method of manufacturing an active matrix flexible display in which a TFT is provided for each pixel, comprising the steps of: (a) preparing a TFT substrate by use of a manufacturing method comprising the steps of: forming a peelable layer on a temporary substrate; forming source and drain electrodes for the TFT on the peelable layer and forming a pixel electrode electrically connected to the drain electrode; forming a gate insulating layer for the TFT, which covers the source electrode, the drain electrode and the pixel electrode; forming a gate electrode for the TFT in a portion on the gate insulating layer on a space between the source and drain electrodes; forming a protective layer which covers the gate electrode; attaching a first plastic film to the protective layer with an adhesive layer interposed therebetween; peeling the temporary substrate from an interface with the peelable layer, and transferring the peelable layer, the source electrode, the drain electrode, the pixel electrode, the gate insulating layer, the gate electrode and the protective layer onto the first plastic film; exposing upper surfaces of the source electrode, the drain electrode and the pixel electrode by removing the peelable layer; forming an organic active layer for the TFT, which is electrically connected to the source and drain electrodes, on the space between the source and drain electrodes; and forming an alignment film above the pixel electrode and the organic active layer; (b) attaching the TFT substrate to a counter substrate with a predetermined space therebetween, the counter substrate having a structure in which a common electrode and an alignment film are formed on a second plastic film; and (c) sealing liquid crystal between the TFT substrate and the counter substrate.
