PROBLEM TO BE SOLVED: To provide a semiconductor device which comprises a first conductive type semiconductor layer, a polysilicon resistor formed via an insulating film on the semiconductor layer, and a second conductive type impurity diffusion region formed on a position which is the principal surface of the semiconductor layer and which corresponds to a portion under the polysilicon resistor, and which amplifies an analog RGB signal. SOLUTION: In an amplifier 1 constituting an amplifier circuit 16, a feedback resistor Rf has a polysilicon resistor 6 formed via a silicon oxide film 5 on an n-type epitaxial layer 3 and a p-type impurity diffusion region 7 formed on a position corresponding to a portion under the polysilicon resistor 6.
