AI Technical Summary

Problems solved by technology

However, a display using such an organic EL device (organic EL display) has disadvantages of low stability and short life over time, so that organic layers in the organic EL device deteriorate due to moisture absorption, which reduces Intensity of luminescence and / or destabilization of luminescence in organic EL devices

Embodiment approach

[0048] [Overall configuration example of an organic EL display]

[0049] figure 1 A cross-sectional configuration of an organic EL display (organic EL display 1 ) according to an embodiment of the present disclosure is shown. The organic EL display 1 is used as an organic EL television receiver or the like. as in figure 2 As shown in , a display region 110A and a peripheral region 110B are disposed on a substrate 11 . The peripheral area 110B is disposed on the outer edge of the display area 110A. The organic EL display 1 may be, for example, a top emission display (see Figure 5 ), in which light of any one color of R (red), (G) green, and B (blue) is emitted from the top surface side (with the substrate 11 on the opposite side of the surface) output. It should be noted that figure 1 is along figure 2 A cross-sectional view of the organic EL display 1 shown in line I-I. image 3 shown in figure 1 An example of the overall configuration of the organic EL display 1 ...

Deformed example 1

[0096] Figure 7 A cross-sectional configuration of an organic EL display (organic EL display 1A) according to Modification 1 is shown. The organic EL display 1A is different from the above-described embodiments in that the high-resistance layer 163 is provided between the organic layer 160 and the upper electrode 162 .

[0097] as in Figure 7 As shown in , the high-resistance layer 163 may, for example, be provided wider than the formation region of the organic layer 160 so as to cover the top surface and side surfaces (end surfaces) of the organic layer 160 . The end face of the high-resistance layer 163 is sealed by the conductive layer 160 and the upper electrode 162 in a similar manner to the organic layer 160 in the above-described embodiment. Examples of materials for the high-resistance layer 163 may include materials with 1 Ωcm to 10 7 Ωcm resistance material. Specific examples of the material of the high resistance layer 163 may include niobium oxide (NbOx), tit...

Abstract

The present invention relates to organic EL displays and electronic equipment. This organic EL display includes: a first insulating layer on a lower side and a second insulating layer on an upper side, the first insulating layer and the second insulating layer being provided to a display area and a peripheral area; a first separating a groove provided in the first insulating layer between the display region and the peripheral region; a first conductive layer provided on the first insulating layer in the peripheral region, wherein the first separation groove a side surface and a bottom of wherein; a covering portion, wherein at least a part of an end face of the second insulating layer is covered by the organic layer or the second electrode; and a sealing portion provided on an outer edge side of the covering portion, And formed by stacking the first conductive layer and the second electrode.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Japanese Priority Patent Application JP2013-74216 filed on March 29, 2013, the entire contents of which are incorporated herein by reference. technical field [0003] The present disclosure relates to an organic electroluminescence (EL) display that emits light by utilizing the organic EL phenomenon, and also relates to electronic equipment including such an organic EL display. Background technique [0004] An organic EL device that emits light by utilizing the EL phenomenon of an organic material has a configuration in which an organic layer including an organic hole transport layer and an organic light emitting layer laminated therein is provided between an anode and a cathode. Such an organic EL device has attracted attention as a light-emitting device capable of high-intensity light emission by low-voltage DC driving. However, a display using such an organic EL device (organi...
