Abstract: Disclosed are an organic light emitting device and a display device using the same in which a light emitting layer includes a host and a plurality of dopants. In the light emitting layer, energy is transferred from a host and other dopants to one dopant by energy transfer system, thus it is possible to increase luminous efficacy of a single color and to increase lifetime of emission.

Abstract: Disclosed is a display panel configured such that, in a structure in which the distance between a display surface and a viewer is short, the structure between a reflective plate and a first electrode (an anode) is changed such that light having three or more color peak properties for all subpixels is transmitted through a second electrode (a cathode), whereby white expression as well as color expression is possible, and a head mounted display device including the same.
