Abstract:
The first light-emitting layer is higher in light-emission start voltage than each of the second light-emitting layer and the third light-emitting layer. The second light-emitting layer is higher in visibility of the emission color than each of the first light-emitting layer and the third light-emitting layer. The electroluminescence layer has an inter-pixel section between an 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 resistance value. The inter-pixel section between the second opening and the third opening has a second resistance value. The inter-pixel section between the third opening and the first opening has a third resistance value. The first resistance value is larger than each of the second resistance value and the third resistance value.
