Abstract

An electroluminescence display device and a manufacturing method thereof are disclosed. The electroluminescence display device may include: a substrate; a first bank layer positioned on the substrate and defining a light emitting region; a first electrode positioned on the light emitting region of the substrate, an end of the first electrode connected to the an end portion of the first bank layer adjacent to without overlapping with the first bank layer; and a light emitting layer on the first electrode.

Description

[0001]Cross-reference[0002]The benefits of this application request from the Korean Patent Application Serial No. 10-2016-0181418 approved on December 28, 2016, which are intended to be incorporated herein by reference in its entirety in this paper.Technical field[0003]Embodiments of the present invention relate to an electroluminescent display device, and more particularly to an electroluminescent display device manufactured by a solution process.Background technique[0004]The electroluminescent display device is provided in a manner formed between the two electrodes in the light-emitting layer. The light-emitting layer emits light through an electric field between the two electrodes, thereby displaying an image on an electroluminescent display device.[0005]The light-emitting layer can be formed from an exciton when the exciton is generated by electrons and holes and the exciton is formed from the excited state to the base state, or may be formed from an inorganic material such as q...
