1. A method of manufacturing an active matrix type display device, the method comprising:
forming active elements each corresponding to a pixel on a device forming substrate of glass;
polishing the device forming substrate to make it thinner by first performing a mechanical polishing, and then performing a chemical polishing, a thickness of the device forming substrate being 5 μm or more but 100 μm or less after polishing the device forming substrate, and a height of projections and depressions of the device forming substrate being in a range of a fiftieth to a half of the thickness;
bonding a surface of the device forming substrate, which has been polished, to a plastic substrate via an adhesion layer; and
forming a display driven by the active elements to display an image pixel by pixel, by placing a counter substrate so as to oppose to the device forming substrate.
