    Abstract: Provided is a display device including first to third pixels and first to fourth cap layers. The first cap layer is located over and overlaps with the first to third light-emitting elements and extends from the first pixel to the third pixel through the second pixel. The second and third cap layers are located over the first cap layer and respectively overlap with the second and third light-emitting elements. The fourth cap layer is located over the first to fourth cap layers. The first to third pixels are arranged in this order. The first to third light-emitting elements are configured so that an emission wavelength of the second light-emitting element is shorter than an emission wavelength of the third light-emitting element and longer than an emission wavelength of the first light-emitting element. A thickness of the third cap layer is larger than a thickness of the second cap layer.

    Abstract: A display device includes a display panel and a housing capable of accommodating the display panel. The display panel includes a first display region and a second display region and is flexible. Display in the first display region and display in the second display region are visually recognizable in a first direction in a state where the display panel is taken out from the housing. The display in the second display region is visually recognizable in a second direction opposite to the first direction in a state where the display panel is accommodated in the housing.

    Abstract: An organic EL display device includes an organic EL element having a first light-emitting portion, a second light-emitting portion, an n-type charge-generation layer, and a p-type charge-generation layer. The first light-emitting portion has a first light-emitting layer and a hole-injection layer. The first light-emitting layer is formed between an anode and a cathode. The hole-injection layer is made of amorphous carbon and in contact with the anode. The second light-emitting portion has a second light-emitting layer, which is formed between the first light-emitting portion and the cathode. The n-type charge-generation layer is formed between the first and second light-emitting portions. The n-type charge-generation layer is in contact with the first light-emitting portion. The p-type charge-generation layer is made of amorphous carbon and formed between the n-type charge-generation layer and the second light-emitting portion. The p-type charge-generation layer is in contact with the second light-emitting portion.
