PURPOSE: To display a highly accurate picture. CONSTITUTION: In this optoelectronic device, although a D/A converter 301 converts input picture data Da into an analog signal to generate a picture signal VID, the output range of the picture signal is controlled by an output range control signal CTLout whose signal level is different in accordance with classifications of liquid crystal display panels 100A, 100B. As a result, the change range of the signal level of the image signal VID can be adjusted in accordance with the classifications of the panels. Thus, even when plural kinds of liquid crystal display panels 100A, 100B having different V-T characteristics and an image signal processing circuit 300A are combined, since respective data values of the input image data Da can be assigned to be within a desired impression voltage range, the optoelectronic device can display the highly accurate image.
