Claim:
1. A display device comprising: an insulating substrate; a light-shielding film formed on the insulating substrate; a first insulating film which covers the light-shielding film; a semiconductor layer formed on the first insulating film, formed of polycrystalline silicon, and including a first impurity area, a second impurity area, and a channel area located between the first impurity area and the second impurity area; a second insulating film which covers the semiconductor layer; a gate electrode formed on the second insulating film and opposed to the channel area; a source line electrically connected to the first impurity area; and an electrode electrically connected to the second impurity area; wherein the first impurity area, the channel area and the second impurity area are integrally connected, the light-shielding film is disposed at a position displaced from a position opposed to the source line, and opposed to an area including a boundary between the channel area and the second impurity area, and the light-shielding film includes an end portion opposed to the channel area and the other end portion opposed to the second impurity area.
