Abstract
An electro-luminescent display panel includes a first substrate having an array of light emitting elements corresponding to a plurality of pixels thereon and a second substrate having light transmissive regions and a reflective light enhancing pattern layer facing the light emitting elements in the first substrate, wherein the reflective light enhancing pattern layer directs oblique light emitted from the light emitting elements to the light transmissive regions. In another aspect, a spacer layer defines a predetermined gap between the first and second substrates. The space layer may provide a light enhancing structure.
