In a reflective liquid crystal display, source/drain electrodes are formed on an insulation substrate and separated from each other. A pixel electrode is provided which has an end portion unitary formed with the source electrode and the pixel electrode extending over the insulation substrate. A semiconductor layer extends over the insulation substrate in contact directly with a gap between the source/drain electrodes and also extends on at least respective parts of the source/drain electrodes for connecting the source/drain electrodes. A gate insulation film extends over entire parts of the semiconductor layer. A gate electrode extends on at least a part of the gate insulation film so that the gate electrode is positioned to cover the semiconductor layer and to be separated by the gate insulation film from the semiconductor layer for shielding the semiconductor layer from incident light. A reflective plate is formed over the pixel electrode so as to be separated from the gate electrode and from the semiconductor layer. An opposite electrode is supported on a surface of an opposite substrate so that the opposite electrode is separated by a space filled with a liquid crystal from the gate electrode and from the reflective plate and also that the opposite electrode faces to the gate electrode and the reflective plate.

A photodetector receiving object light and ambient light as incident light includes: a sensor circuit in which a sensor outputting a first current corresponding to the intensity of the incident light and a sub-sensor outputting a second current corresponding to the intensity of the ambient light are electrically connected in series with each other via a node; and a differential current detection circuit detecting a differential current between the first current and the second current, which is output from the node at the time of applying a voltage across the sensor circuit. Here, when the voltage applied across the sensor circuit is defined as a first voltage and the voltage output from the node is defined as a second voltage, the intensity of the object light is detected on the basis of the differential current created when the second voltage becomes equal to a reference voltage.
