Abstract:
A display device includes: a pixel region in which plural pixels, each including a light emitting element, a capacitor, a drive transistor, and a switch transistor, are arranged in rows and columns; scanning lines; signal lines; and parasitic capacitance which occurs between a source node of the light emitting element of each of the plural pixels and a signal line among the signal lines, wherein when images having different grayscales are displayed in the pixels on adjacent rows which are a 1st-row pixel and a 2nd-row pixel, a difference between a gate-source voltage of the drive transistor of the 1st-row pixel and a gate-source voltage of the drive transistor of the 2nd-row pixel is less than a voltage value of one grayscale, the difference being represented by ΔVdata×Cad/(Cs+Cad+Coled).
