Abstract:
1. A display apparatus including pixels arranged in a matrix, wherein each pixel includes: a selection transistor to be turned on and off by a selection signal from a gate line to control reception of a data signal from a data line; a drive transistor having current flow according to the data signal received through said selection transistor; and a light emitting device emitting light according to the current flowing in said drive transistor, wherein said gate line is disposed along a row direction of each pixel row, two control lines, in addition to the gate line, are disposed along each pixel row in each pixel unit, said gate line is disposed between said two control lines, and on one side of the gate line substantially perpendicular to the row direction, a gate electrode of the selection transistor is formed in a projecting manner, and on an other side of the gate line substantially perpendicular to the row direction and in a column direction opposite to the gate electrode of the selection transistor, a gate electrode of a short-circuit transistor is formed in a projecting manner; the selection transistor is disposed between the gate line and one of the two control lines, and the short-circuit transistor is disposed between the gate line and the other control line; and the short-circuit transistor is connected to a gate electrode of the drive transistor to discharge a potential of the gate electrode of the drive transistor; wherein an end of the selection transistor is connected to the short-circuit transistor through a capacitor, and the gate line is provided so as to cross over and connect between the gate electrode of the selection transistor and the gate electrode of the short-circuit transistor.
