Patent ID: 8692749

Claim:
A display apparatus including pixels arranged in a matrix, wherein each pixel includes: a first transistor having one end connected with a data line, the first transistor being turned on and off by a selection signal from a gate line to control reception of a data signal from the data line; a second transistor which is connected in series between a power source line and a light emitting device, the second transistor, when a voltage in accordance with the data signal received through the first transistor is applied thereto, causing a current from the power source line to flow through the light emitting device in accordance with the data signal; a third transistor which is turned on and off by application of the selection signal to a gate electrode of the third transistor from the gate line and is connected between a gate electrode of the second transistor and one end of the second transistor; and a fourth transistor which is connected in series between the power source line and the light emitting device, the fourth transistor being turned on and off by application of a signal to a gate electrode of the fourth transistor from a line which is provided as a common line for a row of pixels, wherein the third transistor and the fourth transistor are formed with a single continuous semiconductor layer which is provided to be opposed to the gate electrode of the third transistor and the gate electrode of the fourth transistor with an insulation film interposed therebetween, and the third transistor and the fourth transistor are connected with each other through the semiconductor layer.
