摘要：
An electric-field blocking film is provided between a BL insulation film and BL insulation film of a transistor, and a blocking film includes those three layers. The electric-field blocking film blocks an electric field produced by a drain electrode, a source electrode, and an n+-Si film. Even if misalignment of the drain electrode, the source electrode, and the n+-Si film in each drive transistor varies to make a portion overlying an i-Si film larger, therefore, the electric field at this portion is blocked by the electric-field blocking film, thereby making a variation in characteristic smaller.
