Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2016-0182401 filed on December 29, 2016, which is hereby incorporated by reference as if fully set forth herein. technical field [0003] The present invention relates to a display device, in particular to a display device including a touch sensor. Background technique [0004] An electroluminescent display device is a device that has a structure in which a light emitting layer is disposed between two electrodes and thus emits light using an electric field between the two electrodes to display images. [0005] The light emitting layer may be formed of an organic material that emits light when excitons generated by a combination of electrons and holes move from an excited state to a ground state. Alternatively, the light emitting layer may be formed of an inorganic material such as quantum dots. [0006] In electroluminescent display devices, a mo...
