Abstract: Increase in resolution of an organic EL display panel is made achievable with a relatively simple process. An emissive layer of an OLED is formed by stacking an R emissive layer, a G emissive layer, and a B emissive layer corresponding to an R color, a G color, and a B color. The glass-transition temperatures Tg-R, Tg-G, and Tg-B of the R emissive layer, the G emissive layer, and the B emissive layer are set to satisfy Tg-R
Abstract translation: 有机EL显示面板的分辨率的提高可以通过相对简单的过程实现。 OLED的发光层通过层叠发光层，发光层和对应于R颜色，G颜色和B颜色的B发光层来形成。 将发光层，发光层和发光层的玻璃化转变温度Tg-R，Tg-G和Tg-B设定为满足Tg-R

Abstract: A display device, which includes a plurality of unit pixels, includes a plurality of first electrodes respectively corresponding to the plurality of unit pixels, an insulating layer which includes a plurality of through holes, a light emitting element layer, and a second electrode. Each of the plurality of through holes have inner surfaces including a forwardly tapered surface, which is inclined in a direction of enlarging the apertures toward a light emitting direction, and a reversely tapered surface, which is inclined in a direction of reducing the apertures toward the light emitting direction. The forwardly tapered surface is formed between the unit pixels arranged side by side in the first direction. The reversely tapered surface is formed between the unit pixels arranged side by side in the second direction.

Abstract: A display device includes a display panel for displaying a white image; an electrochromic layer stacked on the display panel; a voltage application unit for applying a driving voltage to the electrochromic layer; and a display unit for displaying the white image on the display panel. The electrochromic layer allows a spectrum of light to be transmitted therethrough to be controlled in accordance with the driving voltage applied thereto; and the voltage application unit controls the driving voltage to be applied to the electrochromic layer in synchronization with display of the image on the display panel by the display unit, thus to control the spectrum of the light to be transmitted through the electrochromic layer.
Abstract translation: 显示装置包括用于显示白色图像的显示面板; 堆叠在显示面板上的电致变色层; 电压施加单元，用于向电致变色层施加驱动电压; 以及用于在显示面板上显示白色图像的显示单元。 电致变色层允许光谱通过其传播，以根据施加到其上的驱动电压进行控制; 并且电压施加单元通过显示单元与显示面板上的图像的显示同步地控制施加到电致变色层的驱动电压，从而控制通过电致变色层透射的光的光谱。
