Claim:
1. A method for producing a top-emission organic electroluminescence display device, the top-emission organic electroluminescence display device comprising: a substrate, a plurality of pixel electrodes formed on the substrate, an auxiliary electrode formed between the pixel electrodes adjacent to each other, a spacer portion formed on the substrate, an organic electroluminescence layer formed on the pixel electrodes, comprising a plurality of organic layers, and including at least a luminous layer, at least one layer of the organic layers formed on the auxiliary electrode, a contact portion as an opening of the organic layer, formed on the auxiliary electrode, and a transparent electrode layer formed on the organic electroluminescence layer and the contact portion, the spacer portion being formed between the contact portion and the pixel electrode adjacent to the contact portion, and the transparent electrode layer being electrically connected to the auxiliary electrode in the contact portion; and the method for producing a top-emission organic electroluminescence display device comprising steps of: an organic electroluminescence layer-side substrate preparing step of preparing an organic electroluminescence layer-side substrate comprising the substrate, the pixel electrodes, the auxiliary electrode, the spacer portion, and the organic electroluminescence layer, at least one layer of the organic layers being formed on the whole surface of the auxiliary electrode, an arrangement step of arranging a cover material to face the organic electroluminescence layer-side substrate obtained in the organic electroluminescence layer-side substrate preparing step under a first pressure so that the cover material is in contact with a top portion of the spacer portion by the intermediary of the organic layer, an adhering step of adhering the organic electroluminescence layer-side substrate and the cover material by adjusting a space on the opposite side to the organic electroluminescence layer-side substrate, in relation to the cover material, to a second pressure which is higher than the first pressure, and a contact portion forming step of forming the contact portion by removing the organic layer formed on the auxiliary electrode by illuminating with laser light through the cover material; wherein the cover material is a resin film including a barrier property with an oxygen permeability of 100 cc/m2·day or less, and the cover material is supplied in a roll-to-roll manner.
