  • Publication number: 20240224699
    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.
