Abstract:
1. A display device comprising: a signal line driver; a scan line driver; a power supply line driver; a first wire and a second wire each electrically connected to the signal line driver; a third wire electrically connected to the power supply line driver; a fourth wire electrically connected to the scan line driver; and a first pixel and a second pixel each comprising: wherein the first terminal of the first transistor of the first pixel and the first terminal of the first transistor of the second pixel are electrically connected to the power supply line driver through the third wire, wherein the second electrode of the capacitor of the first pixel is electrically connected to the first wire, wherein the second electrode of the capacitor of the second pixel is electrically connected to the second wire, wherein the gate terminal of the second transistor of the first pixel and the gate terminal of the second transistor of the second pixel are electrically connected to the scan line driver through the fourth wire, wherein the signal line driver is configured to supply video signals to the first wire and the second wire during a writing period, wherein the signal line driver is configured to supply analog potentials having a waveform to the first wire and the second wire during a light emitting period following the writing period, and wherein a maximal amplitude of a video signal supplied to the first wire is different from a maximal potential width of a video signal supplied to the second wire, so that a first length of light emission of the light emitting element of the first pixel is different from a second length of light emission of the light emitting element of the second pixel in a case where the first pixel and the second pixel are configured to emit lights of different colors, and wherein an analog potential having a waveform supplied to the first wire and an analog potential having a waveform supplied to the second wire have a same amplitude regardless of colors of light emission of the light emitting element of the first pixel and of light emission of the light emitting element of the second pixel.
