Abstract
Disclosed are an electroluminescent display device and a method of manufacturing the same. The electroluminescent display device comprises a substrate; a first electrode on the substrate; a connection pattern on the substrate and spaced apart from the first electrode; a bank covering edges of the first electrode and the connection pattern; a light-emitting layer on the first electrode; and a second electrode on the light-emitting layer, the bank and the connection pattern, wherein the connection pattern includes at least one protrusion part and a flat part, each of the first electrode and the connection pattern includes a first layer and a second layer, the second layer is disposed between the substrate and the first layer, and the second layer of the connection pattern has the at least one protrusion part.
Description
[0001] Cross References to Related Applications [0002] This application claims priority to Korean Patent Application No. 10-2019-0161471 filed on December 6, 2019, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to an electroluminescent display device, and more particularly, to an electroluminescent display device having a large size and high definition and a manufacturing method thereof. Background technique [0004] As a flat panel display device, an electroluminescent display device has a wider viewing angle than a liquid crystal display device because it is self-luminous, and has the advantages of thin thickness, light weight, and low power consumption because it does not require a backlight unit. [0005] In addition, electroluminescent display devices are driven by relatively low direct current (DC) voltages and have fast response times. In addition, the electroluminescent display device has strong ex...
