Abstract
In an organic EL display device including a proximity sensor, deterioration in display quality due to irradiation with IR light is suppressed. In the organic EL display device including the proximity sensor is provided with a light shielding unit that prevents a channel layer of a first initialization transistor from being irradiated with IR light, the first initialization transistor being provided in a pixel circuit in order to initialize a voltage that is applied to a control terminal of a drive transistor. The first initialization transistor preferably has a dual-gate structure. The first initialization transistor may have a LDD structure (including a one-side LDD structure).
