Claim:
1. A display device comprising: a pixel comprising: wherein one of a source and a drain of the first transistor is directly connected to the light emitting element or is indirectly connected to the light emitting element through one or more electrical elements other than the first transistor, wherein a gate of the first transistor is directly connected to a first electrode of the capacitor or is indirectly connected to the first electrode of the capacitor through one or more electrical elements other than the first transistor or the capacitor, wherein a second electrode of the capacitor is directly connected to the light emitting element or is indirectly connected to the light emitting element through one or more electrical elements other than the capacitor, wherein one of a source and a drain of the second transistor is directly connected to the light emitting element or is indirectly connected to the light emitting element through one or more electrical elements other than the second transistor, wherein one of a source and a drain of the third transistor is directly connected to the gate of the first transistor or is indirectly connected to the gate of the first transistor through one or more electrical elements other than the third transistor or the first transistor, wherein the other of the source and the drain of the first transistor is directly connected to a first wire or is indirectly connected to the first wire through one or more electrical elements other than the first transistor, wherein the other of the source and the drain of the second transistor is directly connected to a second wire or is indirectly connected to the second wire through one or more electrical elements other than the second transistor, wherein the other of the source and the drain of the third transistor is directly connected to a third wire or is indirectly connected to the third wire through one or more electrical elements other than the third transistor, wherein each of the first transistor, the second transistor and the third transistor comprises In, Ga, Zn and O, wherein the light emitting element is configured to emit white light, and wherein a color filter and the light emitting element overlap each other.
