Abstract

A display device includes a white organic light emitting device. Disclosed herein is a display device capable of improving efficiency and widening a narrow viewing angle by including white organic light emitting devices of a series structure and changing the structure of each sub-pixel.

Description

technical field [0001] The present invention relates to a light emitting device, and more particularly, to a display device capable of improving efficiency and widening a narrow viewing angle by including white organic light emitting devices in a tandem structure and changing the structure. Background technique [0002] With the full advent of the information age in recent years, the field of displays that visually display electrical signals containing information has rapidly developed. Accordingly, various flat panel display devices having excellent characteristics such as thinness, light weight, and low power consumption have been developed, and these flat panel display devices have rapidly replaced existing cathode ray tubes (CRTs). [0003] Specific examples of such flat panel display devices may include liquid crystal display (LCD) devices, plasma display panel (PDP) devices, field emission display (FED) devices, organic light emitting display (OLED) devices, quantum do...
