Display device and electronic device

A display device comprising:

• a display panel comprising a main region comprising a main pixel, and a sub-region comprising a transmission area and a sub-pixel,
• wherein the main pixel comprises first to third main emission areas configured to emit light of first to third colors, respectively,
• the sub-pixel comprises first to third sub-emission areas configured to emit light of the first to third colors, respectively, and
• the display panel comprises:
• a display layer;
• a first color filter layer on the display layer and configured to transmit light of the first color;
• a second color filter layer on the first color filter layer and configured to transmit light of the second color;
• and
• a third color filter layer on the second color filter layer and configured to transmit light of the third color,
• wherein the first color filter layer comprises a first sub-color opening overlapping the second sub-emission area and the third sub-emission area, and a first color transmission window opening in the transmission area,
• the second color filter layer comprises a second sub-color opening overlapping the first sub-emission area and the third sub-emission area, and a second color transmission window opening in the transmission area,
• the third color filter layer comprises a third sub-color opening overlapping the first sub-emission area and the second sub-emission area, and a third color transmission window opening in the transmission area, and
• the second sub-color opening has an area larger than that of at least one of the first sub-color opening or the third sub-color opening.

An electronic device comprising

• a display device, wherein the display device comprises:
• a display panel comprising a main region comprising a main pixel, and a sub-region comprising a transmission area and a sub-pixel,
• wherein the main pixel comprises first to third main emission areas configured to emit light of first to third colors, respectively,
• the sub-pixel comprises first to third sub-emission areas configured to emit light of the first to third colors, respectively, and
• the display panel comprises:
• a display layer;
• a light blocking layer on the display layer;
• a first color filter layer on the light blocking layer and configured to transmit light of the first color;
• a second color filter layer on the first color filter layer and configured to transmit light of the second color;
• and
• a third color filter layer on the second color filter layer and configured to transmit light of the third color,
• wherein the first to third color filter layers comprise first to third main color portions overlapping the first to third main emission areas, respectively, and first to third sub-color portions overlapping the first to third sub-emission areas, respectively, and
• an area ratio between the first to third main color portions is different from an area ratio between the first to third sub-color portions.
