US Patent 11640191 Display device and electronic apparatus

In a display device including: a pixel array unit made up of pixels disposed on a substrate; a peripheral circuit unit that is disposed in a periphery of the pixel array unit and drives the pixels; and a temperature sensor circuit disposed on the same substrate as the pixels, the temperature sensor circuit is configured using an inverter circuit including a plurality of inverters made up of thin film transistors. Then, crystallinity of a channel portion of the thin film transistor of the temperature sensor circuit is different from crystallinity of a channel portion of a thin film transistor constituting the peripheral circuit unit.
