ABSTRACT:
An organic electroluminescent (EL) display device is provided which includes a film with a multi-dimensional grating pattern formed on a surface thereof. The display device includes a transparent substrate, a first electrode formed on the transparent substrate, an organic light emitting layer formed on the first electrode, a second electrode formed on the organic light emitting layer. The is provided at a bottom of the transparent substrate. A display device employing this film with a multi-dimensional grating pattern provides improved light emitting efficiency and enhanced image quality.
