Patent ID: 8536568

Claim:
A display device comprising: a lighting portion comprising a first substrate, a second substrate, an organic electroluminescent portion disposed on the first substrate and a sealing layer attaching the first substrate to the second substrate so as to seal the organic electroluminescent portion therebetween, the organic electroluminescent portion comprising a patterned anode layer disposed on the first substrate, a patterned organic layer disposed on the patterned anode layer and made of a semitransparent electrode material or a transparent electrode material, and a patterned cathode layer disposed on the patterned organic layer; and a reflective liquid crystal display device attached to the first substrate and comprising a third substrate, a plurality of reflective pixel electrodes disposed on the third substrate, a liquid crystal layer disposed over the reflective pixel electrodes and a common electrode disposed on the liquid crystal layer, the reflective pixel electrodes being configured to receive light emitted from the lighting portion and define pixels of the display device, wherein a width of a pattern of the patterned cathode layer is larger than a width of a pattern of the patterned organic layer, and a width of a pattern of the patterned anode layer is smaller than the width of the patterned organic layer, the organic electroluminescent portion is disposed on the first substrate so that the entire organic electroluminescent portion is on a top flat surface of the first substrate so as to extrude from the top flat surface, and the first substrate is disposed between the reflective liquid crystal display device and the second substrate; wherein each of the patterned anode layer, the patterned organic layer, and patterned cathode layer has a rectangular cross-section.
