Method for manufacturing display device having flexibility
A display device comprises an organic EL substrate including an organic EL layer formed on a flexible substrate and a first main surface of the flexible substrate; a film covering a display region of the organic EL substrate; and a terminal region arranged at an end portion of the organic EL substrate, and arranged adjacent to and apart from an end portion of the film. The end portion of the film may have a taper region. A thickness of the taper region increases with distance from the terminal region in a cross-sectional view. A width of the taper region may be 0.5 times or more and 1.5 times or less of the film thickness in a plan view.
1. A method for manufacturing a display device comprising:
forming an organic EL substrate by forming an organic EL layer on a first main surface of a flexible substrate;
forming a terminal region in an end portion of the organic EL substrate; and
covering a display region of the organic EL substrate with a film, cutting the film along a first cutting line by a first laser, and cutting the organic EL substrate along a second cutting line by a second laser,
wherein the film has a taper region, the thickness increases with distance from the terminal region in a cross-sectional view; and
the cutting end position is in a range of the taper region.
2. The method for manufacturing a display device according to claim 1 , wherein
the cutting start position of the film by the first laser is in a range of the taper region.
