Display device and electronic device

A display device, comprising:

• a first sub-pixel area allowing a light of a first main wavelength transmitting therethrough having a first cell gap;
• a second sub-pixel area allowing a light of a second main wavelength transmitting therethrough having a second cell gap;
• a third sub-pixel area allowing a light of a third main wavelength transmitting therethrough having a third cell gap;
• a first interdigitated electrode disposed in the first sub-pixel area, having first electrode strips parallel to each other, wherein the first electrode strips have a first electrode width and a first electrode slit, and wherein the first sub-pixel area has a first ratio of the first electrode width to the first electrode slit of the first electrode strips;
• a second interdigitated electrode disposed in the second sub-pixel area, having second electrode strips parallel to each other, wherein the second electrode strips have a second electrode width and a second electrode slit, and wherein the second sub-pixel area has a second ratio of the second electrode width to the second electrode slit of the second electrode strips;
• and
