Abstract: PROBLEM TO BE SOLVED: To obtain an active matrix panel with a high definition, compactness, and a high reliability at low cost, by forming the gate length of P-type and N-type TFTs shorter than that of TFTs constituting a picture element matrix. SOLUTION: Within a limit permitted by a breakdown strength, the gate length of TFTs constituting a drive circuit 12 is formed as short as possible. Also, since TFTs forming sample hold circuits 17-19 can have a lower breakdown strength than TFTs forming a shift register 13, the gate length is formed further shorter than that of TFTs forming the shift register. Namely, it becomes possible to improve the drive circuit 12 in the operation speed and further keep a write and hold operation in an optimal state at each picture element by forming the gate length of TFTs constituting the drive circuit 12 shorter than that of TFTs constituting an active matrix.
