Organic electroluminescence display device
An OLED display device having a laminate encapsulating structure containing: an OLED substrate having a leading wire and a pixel area which carries a number of OLEDs on a glass substrate; and an encapsulating plate; and a filler filling a space between the OLED substrate and the encapsulating plate, wherein the filler is dispersed with a desiccant and fine metallic partides for improving electroconductivity and thermoconductivity. This structure not only can prevent an inflow of moisture into the OLEDs and secure a mechanical strength of the OLED display device as a flat panel display device, but also accelerate a heat radiation and improves electroconductivity of a conductive layer.
