摘要：
An optical sensor circuit (20) includes a transistor (20c) and a transistor (20d). The transistor (20c) is connected in series with the transistor (20d). The transistor (20d) is configured to receive light. A black matrix is provided so as to face the transistor (20c). A voltage generated at a connecting point (i.e., node (netB)) of the transistor (20d) and the transistor (20c) varies depending on intensity of light received via the transistor (20d).
