Abstract:
An audio signal processing circuit for processing an audio signal which is compact and small is provided. For the audio signal processing circuit of the invention, an input circuit, a feedback circuit, and a smoothing circuit are formed using a chip capacitor with small mounting space and a thin film resistor on an insulating substrate. Accordingly, the audio signal processing circuit that is small and further a display device incorporating the audio signal processing circuit are provided.
