Patent ID: 8508439

Claim:
A display device comprising: a driver circuit; and a pixel electrically connected to the driver circuit, the pixel comprising: a first thin film transistor; a second thin film transistor; a resistor; an EL element; and a color filter, wherein a gate of the first thin film transistor is electrically connected to a first line, wherein one of a source and a drain of the first thin film transistor is electrically connected to a second line, wherein the other of the source and the drain of the first thin film transistor is electrically connected to a gate of the second thin film transistor, wherein one of a source and a drain of the second thin film transistor is electrically connected to a third line, wherein the other of the source and the drain of the second thin film transistor is electrically connected to the EL element, wherein the resistor is electrically connected to the second thin film transistor in series between the third line and the EL element, wherein the EL element is capable of emitting green light, wherein the color filter is capable of extracting green light, wherein the EL element overlaps with the first thin film transistor and the second thin film transistor, and wherein the first line is a gate line.
