Patent ID: 8373344

Claim:
An organic electro-luminescence EL display device comprising: a thin film transistor array unit formed on a lower substrate; an organic EL array unit on the thin film transistor array unit having a matrix of organic EL cells; a glass cap bonded to the lower substrate with sealant at edges of the lower substrate for protecting the organic EL array unit, wherein the glass cap comprises: a vertical portion bonded to the lower substrate with the sealant; a horizontal portion connected to the vertical portion to face the organic EL array unit including a first region, and a second region having recesses each with a thickness thinner than the first region, wherein the first region has a difference of thickness from the second region that is greater than a thickness of a moisture absorbent; moisture absorbent within each of the recesses; a plastic film disposed between the organic EL array unit and the glass cap and attached to the first region of the glass cap, wherein the plastic film is spaced from the organic EL array unit; and a metal wiring formed on a sidewall of the plastic film, wherein the glass cap, the lower substrate and the sealant define a sealed environment of which a pressure is higher than an atmospheric pressure.
