Abstract:
1. A display device comprising: a pixel area comprising pixels arranged in a matrix, and having a horizontal resolution of 350 ppi or more, the pixels each comprising a first transistor, a second transistor, a capacitor and a light-emitting element; and a color filter layer overlapping with the pixel area, wherein in each of the pixels, the first transistor comprises a first region of a first single crystal semiconductor layer, the capacitor comprises a second region of the first single crystal semiconductor layer, and the second transistor comprises a second single crystal semiconductor layer which is spaced from the first semiconductor layer, wherein a gate of the first transistor is electrically connected to a first line, wherein the capacitor further comprises a portion of a conductive film over the first single crystal semiconductor layer, wherein one of a source and a drain of the first transistor is electrically connected to a second line, wherein a gate of the second transistor 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 second transistor is electrically connected to the light-emitting element, wherein the other of the source and the drain of the second transistor is electrically connected to a third line, wherein the conductive film extends substantially parallel to the first line, wherein the conductive film intersects with the second line and the third line, wherein the third line is separated from the conductive layer, and wherein the light-emitting element is configured to emit white light.
