Abstract
The present disclosure relates to a display device. According to the present disclosure, since conductive layers disposed on a substrate include a layer formed of a material having a low reflectance, defects in which the conductive layers are visually recognized by a user and visibility decreases can be resolved.
Claims25
A display device, comprising:
- a substrate;
- and
- a conductive stack on the substrate, the conductive stack including:
- a first conductive layer including a first sub-conductive layer and a second sub-conductive layer disposed on the first sub-conductive layer;
- and
- a second conductive layer disposed on the first conductive layer, the second conductive layer including a first sub-conductive layer and a second sub-conductive layer disposed on the first sub-conductive layer,
- wherein the first sub-conductive layer of the first conductive layer includes at least one selected from among a first low-reflective material, a second low-reflective material, and a third low-reflective material,
- wherein the first low-reflective material includes a first metal, a first metal oxide, a second metal oxide, and a third metal oxide;
- wherein the second low-reflective material includes a second metal and two or more different conductive oxides;
- and
- wherein the third low-reflective material including a fourth metal oxide and two or more different conductive oxides,
- wherein the first sub-conductive layer of the second conductive layer includes at least one selected from the second low-reflective material and the third low-reflective material.
