摘要:
An organic EL display device includes a first organic EL element which includes a first organic layer including a first light emission layer which emits the color of light in the first wavelength range and a hole blocking layer between a pixel electrode and a counter-electrode, a second organic EL element which includes a second organic layer including a second light emission layer which emits the color of light in the first wavelength range between a pixel electrode and the counter-electrode, the second organic EL element being thinner than the first organic EL element, and a third organic EL element which includes a third organic layer including the third light emission layer which emits the color of light in the first wavelength range between a pixel electrode and the counter-electrode, the third organic EL element being thicker than the first organic EL element.
