Abstract

A method for producing an organic EL display device in an embodiment includes step (a) of forming a polymer film (14) on a support substrate (12); step (b) of forming a plurality of organic EL display panel portions (20) on the polymer film (14); and step (c) of causing the organic EL display panel portions (20) on a stage (200S) to face the stage (200S), and directing a line beam (100L) in a direction from the support substrate (12) toward at least an interface between the polymer film (14) and the support substrate (12) while moving the line beam (100L) and the support substrate (12) with respect to each other, the step (c) being performed in a state where the organic EL display panel portions (20) are substantially thermally insulated from the stage (200S).

First claim

The invention claimed is:

1. A method for producing an organic Electro-Luminescence (EL) display device, comprising:
forming a polymer film on a support substrate;
forming a plurality of organic EL display panel portions on the polymer film; and
positioning the support substrate with the plurality of organic EL display panel portions on a stage and arranging the plurality of organic EL display panel portions on the support substrate to face the stage; maintaining a distance between the plurality of organic EL display panel portions and the stage by a spacer member inserted between the stage and a region in the support substrate, the spacer member being spaced apart from the plurality of organic EL display panel portions; and
directing a line beam in a direction from the support substrate toward at least an interface between the polymer film and the support substrate while moving the line beam and the stage with respect to each other;
wherein the line beam is moved in a first direction, and the stage is moved in a second direction opposite to the first direction; the spacer member defines an opening and comprises a stepped portion surrounding the opening.

2. The method for producing an organic EL display device of claim 1 , wherein forming the plurality of organic EL display panel portions comprises forming the plurality of organic EL display panel portions arrayed in at least one line.

3. The method for producing an organic EL display device of claim 2 , wherein the method further comprises mounting a driving circuit on the plurality of organic EL display panel portions arrayed in the at least one line before positioning the support substrate with the plurality of organic EL display panel portions on the stage.

4. The method for producing an organic EL display device of claim 1 , wherein the spacer member is made of glass or aluminum.
