Problems solved by technology

However, although oxygen intrusion is thereby prevented, it is still difficult to maintain a constant substrate interval when an organic EL display is enlarged.
In the case of a top-emission organic EL display, interference fringes appear on the sealing substrate as the display surface, resulting in a decrease in the display quality of the display

Abstract

To provide an organic EL display and its manufacturing method without causing the degradation of an organic EL element due to oxygen or the like and without the deterioration of display quality even if the display has a large screen. The organic EL display (10) includes an element base plate (12), a plurality of organic EL elements (14) arranged vertically and horizontally on the element base plate (12), barrier ribs (16) set for each organic EL element (14) so as to surround it on the base plate (12), a sealing base plate (18) opposed to the element base plate (12) and adhered to the barrier ribs (16), and a sealant (20) for sealing the organic EL elements (14) and the barrier ribs (16) at the same time at peripheral edges of the element base plate (12) and the sealing base plate (18).

Description

technical field [0001] The invention relates to an organic EL display and a manufacturing method thereof. Background technique [0002] Such as Figure 4 As shown in (a) and (b), organic EL elements 54 are arranged vertically and horizontally on an element substrate 52 of a well-known organic EL display 50 . The organic electrogenic element 54 is a structure in which an organic light-emitting layer is sandwiched between an anode electrode and a cathode electrode. The element substrate 52 and the sealing substrate (also called a sealing cover) 58 face each other, and the organic EL element 54 is sealed by bonding the peripheral regions of the two substrates 52 and 58 with the sealant 60 . Such as Figure 4 As shown in (b), partition walls 56 are provided in the longitudinal direction of the substrate 52 . The element substrate 52 and the sealing substrate 58 adopt a glass substrate and a metal cover. The organic EL display 50 performs display by light emission of the organ...
