Abstract: A display device includes an array of sub-pixels including red, green, and blue sub-pixels, and an input sensing layer including a metal pattern at least partially surrounding each of the sub-pixels in a plan view. The array has a structure in which an ith column (where i is a natural number), in which the red sub-pixels and the green sub-pixels are alternately arranged, and an (i+1)th column, in which the blue sub-pixels are arranged, are alternately arranged. The metal pattern includes a first metal pattern partially surrounding a first sub-pixel, which is one of the sub-pixels, and a second metal pattern completely surrounding a second sub-pixel emitting light of a same color as the first sub-pixel. The first metal pattern includes a first open portion extending from the first sub-pixel in a first direction and a second open portion extending from the first sub-pixel in a second direction.

Abstract: Disclosed is a method of fabricating a display device. The method comprises forming a dielectric layer on an encapsulation layer including a first encapsulation region and a second encapsulation region adjacent to the first encapsulation region, forming a conductive layer on the dielectric layer, forming a first photoresist layer on the conductive layer that overlaps each of the first and second encapsulation regions, forming a second photoresist layer on the first photoresist layer that overlaps the second encapsulation region, and etching the conductive layer based on the first and second photoresist layers. When viewed in a thickness direction of a display panel including the encapsulation layer, at least a portion of the encapsulation layer overlapping the second encapsulation region has a thickness greater than that of the encapsulation layer overlapping the first encapsulation region.
