Semiconductor device and manufacturing method thereof

摘要

A display device including TFT elements having satisfactory characteristics and being easy to assemble. In the display device, a pixel emitting red light comprises a red color filter. The red color filter forms a light shielding film for the TFT elements in a driver circuit portion or in a pixel portion.

1. A display panel comprising:
a substrate; an interlayer insulating film; a pixel portion over the substrate and comprising:
first pixels configured to emit red light and each comprising:
a first transistor comprising a first semiconductor layer;the interlayer insulating film over the first transistor; anda first electrode over the interlayer insulating film and electrically connected to the first semiconductor layer via a first opening in the interlayer insulating film;second pixels configured to emit light other than red light and each comprising:
a second transistor comprising a second semiconductor layer;a second electrode over the interlayer insulating film and electrically connected to the second semiconductor layer via a second opening in the interlayer insulating film; anda pixel color filter overlapping with the second electrode; and a first red color filter extending continuously to overlap with the first and the second transistors and with the first electrodes of the first pixels configured to emit red light, and wherein the first red color filter comprises openings overlapping with the second electrodes of the second pixels configured to emit light other than red light.
