DISPLAY APPARATUS HAVING A LIGHT-EMITTING DEVICE

Abstract: discussed is display apparatus in which a light-emitting device includes a charge generation layer and at least one hole transport layer is provided. the hole transport layer and/or the charge generation layer of each pixel area can be spaced apart from the hole transport layer and/or the charge generation layer of adjacent pixel area. the hole transport layer and/or the charge generation layer on the pixel area displaying a blue color can include a content of p-type dopant lower than the hole transport layer and/or the charge generation layer on the pixel region that displays a color other than blue. thus, in the display apparatus, a leakage current between the pixel areas can be minimized. therefore, in the display apparatus, efficiency of each pixel area can be improved.
