OLED including inter-pixel sections having different resistances

A display device comprising:

• a plurality of pixel electrodes;
• an insulation layer with a plurality of openings for the respective plurality of pixel electrodes, the insulation layer covering a peripheral portion of each of the plurality of pixel electrodes;
• and
• an electroluminescence layer on an upper surface of the insulation layer, the electroluminescence layer including a plurality of light-emitting layers, the plurality of light-emitting layers overlapping with the respective plurality of pixel electrodes inside the respective plurality of openings,
• wherein
• the plurality of light-emitting layers include a first light-emitting layer configured to emit blue light, a second light-emitting layer configured to emit green light, and a third light-emitting layer configured to emit red light, and the plurality of light-emitting layers are adjacent to each other,
• the first light-emitting layer is higher in a voltage to start light-emission than each of the second light-emitting layer and the third light-emitting layer,
• the plurality of openings include a first opening overlapping with the first light-emitting layer, a second opening overlapping with the second light-emitting layer, and a third opening overlapping with the third light-emitting layer,
• the electroluminescence layer includes a plurality of inter-pixel sections including an inter-pixel section between each adjacent pair of the openings and along the upper surface of the insulation layer,
• the inter-pixel section between the first opening and the second opening has a first electrical resistance value, the inter-pixel section between the second opening and the third opening has a second electrical resistance value, and the inter-pixel section between the third opening and the first opening has a third electrical resistance value, and
• the first electrical resistance value is larger than each of the second electrical resistance value and the third electrical resistance value.
