Patent ID: 8735900

Claim:
A display device comprising: a first pixel over a first substrate; a second pixel over the first substrate, the second pixel being adjacent to the first pixel; a first line; a second line; a third line; a fourth line; a second substrate; a first color filter between the first substrate and the second substrate; and a second color filter between the first substrate and the second substrate; wherein the first pixel comprises a first transistor, a second transistor and a first electroluminescence element, wherein the second pixel comprises a third transistor, a fourth transistor and a second electroluminescence element, wherein one of a source and a drain of the first transistor is electrically connected to the first line, wherein one of a source and a drain of the second transistor is electrically connected to a gate of the first transistor, wherein the other of the source and the drain of the second transistor is electrically connected to the second line, wherein a gate of the second transistor is electrically connected to the fourth line, wherein the first electroluminescence element is electrically connected to the other of the source and the drain of the first transistor, wherein one of a source and a drain of the third transistor is electrically connected to the first line, wherein one of a source and a drain of the fourth transistor is electrically connected to a gate of the third transistor, wherein the other of the source and the drain of the fourth transistor is electrically connected to the third line, wherein a gate of the fourth transistor is electrically connected to the fourth line, wherein the second electroluminescence element is electrically connected to the other of the source and the drain of the third transistor, wherein the first color filter comprises a first region that overlaps with the first electroluminescence element, wherein the second color filter comprises a second region that overlaps with the second electroluminescence element, wherein the first color filter has a first color, wherein the second color filter has a second color different from the first color, wherein the first color filter overlaps with the second transistor, and wherein the first color is red.
