Problems solved by technology

However, in order to realize a high-definition organic EL display with side-by-side patterning of RGB subpixels using a mask, the patterning of pixels of different colors is extremely difficult.
[0005] In contrast, some organic EL displays are not based on the patterning of RGB subpixels using a mask

[0044] 4. Application example (electronic equipment)

[0045]

[0046] [1-1. System Configuration]

[0047] figure 1is a system configuration diagram showing a brief configuration of an active matrix organic EL display to which the present disclosure is applied.

[0048] The active matrix organic EL display uses active elements such as insulated gate field effect transistors provided on the same pixel as the organic EL elements to control the current flowing through the organic EL elements, ie, current-driven electro-optical elements. TFTs (Thin Film Transistors) are generally used as Insulated Gate Field Effect Transistors.

[0049] like figure 1 As shown, the organic EL display 10 according to this application example includes a plurality of pixels 20 each having an organic EL element, a pixel array section 30 , and a driving circuit section provided around the pixel array section 30 . The pixel array section 30 includes pixels 20 arranged in a two-dimensional matrix...

Abstract

An organic electroluminescence display has a bottom emission structure in which a white organic electroluminescence element adapted to emit white light is formed, pixel by pixel, on a substrate, and in which light emitted by the white organic electroluminescence element is extracted from a rear side of the substrate. The organic electroluminescence display includes: a color filter used in combination with the white organic electroluminescence element to extract light of different colors; and metal interconnects formed, pixel by pixel, in such a manner as to surround a light-emitting section of the white organic electroluminescence element and the color filter.

Description

technical field [0001] The present disclosure relates to organic EL displays and electronic devices. Background technique [0002] Among flat panel displays, some employ a so-called current-driven electro-optical element whose luminance of light emission changes according to the current flowing through the device as a light-emitting portion (light-emitting element) of each pixel. An organic EL element based on electroluminescence (EL) of an organic material and emitting light when an electric field is applied to an organic thin film is known as a current-driven electro-optical element. [0003] An organic EL display employing an organic EL element as a light emitting portion of each pixel has the following features. That is, by applying a voltage of 10 V or less, the organic EL element can be driven, making the power consumption of the organic EL display low. Organic EL elements are self-luminous, thus allowing organic EL displays to provide higher visibility than liquid c...
