Abstract

A display device may include: a plurality of sub-pixels disposed on a substrate; a storage capacitor disposed in each of the plurality of sub-pixels; a buffer layer disposed on the storage capacitor; a transistor disposed in each of the plurality of sub-pixels and on the buffer layer; and a light emitting element disposed in each of the plurality of sub-pixels and on the transistor, in which the plurality of sub-pixels includes a first sub-pixel, a second sub-pixel, and a third sub-pixel, each of the first sub-pixel, the second sub-pixel, and the third sub-pixel being configured to emit light of different colors, and each of the first sub-pixel, the second sub-pixel, and the third sub-pixel being configured to emit light of different colors. At least one of the plurality of sub-pixels includes a metal layer disposed below the transistor, and the metal layer is connected to one electrode of the storage capacitor.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims priority from Korean Patent Application No. 10-2020-0189238 filed in the Republic of Korea on December 31, 2020, the entire contents of which are expressly incorporated herein by reference. technical field [0003] The present disclosure relates to a display device, and more particularly, to a display device capable of improving quality by applying an S-factor optimized for each sub-pixel. Background technique [0004] Recently, as our society develops toward an information-oriented society, the field of display devices for visually expressing electrical information signals has rapidly developed. Accordingly, various display devices having excellent performance in thinness, lightness, and low power consumption are being developed. [0005] Specific examples of such display devices include liquid crystal displays (LCDs) and electroluminescent display devices such as organic light emitting display...
