An organic EL display device includes a light modulating unit layer, a TFT layer, and a plurality of organic EL elements layered in the stated order. A top-emitting single-sided display emitting light emitted from a light emitting layer from an upper electrode side and a double-sided display emitting light emitted from the light emitting layer from each of the upper electrode side and a lower electrode side are electrically switched.

Display device configured to switch between single-sided and double-sided display

Provided is a display apparatus where: a blue light-emitting layer is formed as a layer that is common to a first subpixel, a second subpixel, and a third subpixel; a green light-emitting layer is formed as a layer that is common to the second subpixel and the third subpixel; and the red light-emitting layer is formed only in the third subpixel.

Display apparatus and method for manufacturing same

Provided is a display apparatus where: a red light-emitting layer is formed as a layer that is common to a first subpixel, a second subpixel, and a third subpixel; a blue light-emitting layer is formed as a layer that is common to the first subpixel and the second subpixel; and the green light-emitting layer is formed only in the second subpixel.

A hole injection layer provided between a first electrode and each of light emitting layers, and an electron injection layer provided between a second electrode and each of light emitting layers, overlap only inward from an end portions each of the light emitting layers when viewed in plan view.

El display device including island shaped hole injection layer and island shaped electron injection layer and method of manufacturing the same

Provided is a display apparatus where: a green light-emitting layer is common to a first subpixel, a second subpixel, and a third subpixel; a blue light-emitting layer is formed solely in the first subpixel; the red light-emitting layer is formed solely in the third subpixel; and in the first subpixel a separation layer is formed between the blue light-emitting layer and the green light-emitting layer.
