Abstract
A production method for an OLED panel includes forming on an upper face side of a transparent substrate, a layered body including a resin layer, a TFT layer, an OLED layer and a sealing layer including an organic sealing film, and then irradiating the resin layer being in contact with the transparent substrate with a laser beam to separate the transparent substrate and the layered body. In the production method, the resin layer includes a first region to be irradiated with a laser beam at a first intensity P1 and a second region to be irradiated with a laser beam at a second intensity P2 greater than the first intensity, the first region overlaps with the organic sealing film, and the second region does not overlap with the organic sealing film.
Claims7
An OLED panel comprising:
- on an upper surface side of a flexible base material, a laminate including:
- a resin layer;
- a TFT layer including an inorganic insulating film;
- an OLED layer;
- and
- a sealing layer including an inorganic sealing film and an organic sealing film,
- wherein the resin layer includes a first region overlapping with the inorganic sealing film, the inorganic insulating film and the organic sealing film, and a second region overlapping with the inorganic sealing film and the inorganic insulating film, but not overlapping with the organic sealing film,
- a recessed portion is provided in at least a portion of the second region, and
- the recessed portion is provided in a surface of the resin layer on a flexible base material side of the resin layer.
