Abstract

A display device including a liquid crystal held between an active matrix substrate made up by arranging thin film transistors thereon, each using polycrystalline silicon as a semiconductor layer, in one-to-one relation to intersections between a plurality of signal lines and a plurality of scan lines, and an opposite substrate opposed to the active matrix substrate, wherein the active matrix substrate includes a film having tensile stress disposed at least below or above the semiconductor layer.
