Abstract
Official abstract text for this publication.
A flexible display supporting substrate of the present disclosure includes: a glass base (11); a plastic film (12) which has a surface (12s), the surface having a polish recess (12c), the plastic film being supported by the glass base (11); and an oxide layer (20) overlying a part of the surface (12s) of the plastic film (12) and covering at least part of the polish recess (12c).
First claim
Opening claim text (preview).
The invention claimed is: 1. A flexible display production method comprising: providing a flexible display supporting substrate which includes a glass base and a plastic film on the glass base; polishing a part of a surface of the plastic film, thereby forming a polish recess in the surface of the plastic film; and forming a sintered layer so as to locally cover at least part of the polish recess in the surface of the plastic film, wherein forming the sintered layer includes supplying a liquid material locally to the polish recess formed in the surface of the plastic film, and forming the sintered layer from the liquid material by irradiating the liquid material with an infrared light beam emitted from an infrared light source to locally heat the liquid material. 2. The method of claim 1 , wherein the liquid material is a sol which contains an alkoxide. 3. The method of claim 1 , wherein forming the sintered layer includes heating the liquid material to 350° C. or higher. 4. The method of claim 1 , comprising forming a first gas barrier film so as to cover the surface of the plastic film, forming an OLED device so as to be supported by the flexible substrate, and forming a second gas barrier film so as to be supported by the flexible substrate and so as to cover the OLED device.
