Abstract: A flat portion includes a corner side that is provided between the first and second sides and of which a tangent intersects the first and second sides. An inclined portion includes a first portion that is bent along the first side, a second portion that is bent along the second side, and a third portion that is bent from the corner side.

Abstract: There are provided pixel units arrayed in a matrix, and a signal line driving circuit. The signal line driving circuit divides a 1 frame into a first period in which a video signal is supplied to the pixel unit of a high gray level and a second period in which a video signal is supplied to the pixel unit of a low gray level, supplies in the first period a video signal current, which has a current value that is A-times (A>0) higher than a current value corresponding to high-gray-level display, to the pixel unit of the high gray level, and supplies in the second period a video signal current, which has a current value that is N-times (N>A) higher than a current value corresponding to low-gray-level display, to the pixel unit of the low gray level, thus writing the video signal in the pixel unit.

Abstract: A plurality of display pixels arranged in a matrix form respectively have a self-luminescent element, a driving transistor which controls an electric current amount made to flow in the self-luminescent element, in accordance with an image signal, and a switch formed of a thin-film transistor and connected between a gate and a drain of the driving transistor. The switch is controlled to be turned on and off by a control signal Sb supplied via a scanning line Cg from a scanning line driving circuit. When the switch is in an ON-state, an electric potential of the control signal is varied in a stepwise manner so as to be close to an electric potential for making the switch be in an OFF-state.
