Title:
DISPLAY DEVICE
Document Type and Number:
Japanese Patent JP2021170111
Kind Code:
A
Abstract:
To provide a display device with reduced variations in luminance among pixels.SOLUTION: The display device includes a transistor, first to fourth switches, first and second capacitors, a light-emitting element, and first to fifth wirings. The transistor comprises a first gate and a second gate. A first terminal of the transistor is connected to the third wiring. The first switch controls a conduction state between the first wiring and the first gate, the second switch controls a conduction state between the second wiring and the second gate, the third switch controls a conduction state between the first gate and a second terminal of the transistor, and the fourth switch controls a conduction state between the fifth wiring and the second terminal of the transistor. The first capacitor retains a potential difference between the first gate and the second terminal of the transistor, and the second capacitor retains a potential difference between the first gate and the second gate. The first terminal of the light-emitting element is connected to the second terminal of the transistor, and the second terminal of the light-emitting element is connected to the fourth wiring.SELECTED DRAWING: Figure 1
