Abstract
Disclosed is an organic EL display panel and a manufacturing the same, the EL display panel including an organic EL display panel including a bulkhead for insulating an emitting cell from an anode strip, the emitting cell having an ITO strip, a supplement electrode, an organic EL layer, and the anode strip, and at least one supplement bulkhead for coupling the bulkheads for preventing the sealant is injected along the bulkhead to the emitting cell thereby an inferior device is reduced and yield is increased.
Claims24
An organic EL display device, comprising:
- a substrate having a display area and a non-display area;
- an insulating layer provided over the substrate;
- an array of light emitting elements formed over the display area of the substrate, each light emitting element comprises an anode, a cathode and an electroluminescent layer provided between the anode and the cathode;
- a cover to cover the array of light emitting elements;
- a sealant provided in the non-display area between the cover and the substrate and provided near the periphery of the cover;
- a sealant barrier formed on the insulating layer and around the array of the light emitting elements, wherein the sealant barrier is formed in the non-display area between the array and the sealant and wherein the sealant barrier includes a structure comprising:
- a first portion arranged in a first direction,
- a second portion that extends from the first portion and is arranged in a second direction which crosses the first direction, and
- a third portion that extends from the second portion and is arranged substantially in the first direction or another direction, wherein the first portion is a first distance from the array of light emitting elements and the second portion is a second distance from the array of light emitting elements and wherein the second distance is greater than the first distance.
The organic EL display device, wherein each of the sealant barrier sections is oriented at substantially a same predetermined angle relative to corresponding ones of the plurality of row barriers.
An organic EL display, comprising:
- a substrate having a display area and a non-display area;
- an insulating layer provided over the substrate;
- an array of light emitting elements formed in the display area of the substrate, each light emitting element comprising an anode , a cathode, and an electroluminescent layer between the anode and the cathode;
- a cover to cover the array of light emitting elements;
- a sealant provided in the non-display area between the cover and the substrate and provided adjacent a periphery of the cover;
- a sealant barrier formed on the insulating layer and around the array of the light emitting elements, the sealant barrier formed in the non-display area between the array and the sealant, wherein the sealant barrier has a structure which includes:
- a first portion arranged in a first direction,
- a second portion that extends from the first portion and is arranged in a second direction crossing the first direction, and
- a third portion that extends from the second portion and is arranged in substantially the first direction or another direction, wherein the first portion is separated from the array of light emitting elements by a first distance and the second portion is separate from the array of light emitting elements by a second distance greater than the first distance, and wherein the second portion and third portion are formed over the anode.
