  • Patent number: 9978827
    Abstract: Provided are an organic EL display device and a method of manufacturing the organic EL display device for preventing damage caused in a process of exposing terminals and for improving light extraction from the display. A glass substrate is removed from a panel that is formed by sequentially laminating a TFT substrate, a sealing film, a flexible substrate layer, and the glass substrate. A portion of the flexible substrate layer is removed that is formed on a position corresponding to a terminal part of the TFT substrate. A transparent thin film is formed on the flexible substrate layer, and a portion of the sealing film is removed by using the transparent thin film as a mask. The portion of the sealing film is formed on the position corresponding to the terminal part of the TFT substrate.

  • Patent number: 8877520
    Abstract: A method for manufacturing a ferroelectric film including the steps of forming a burnable material film containing hydrogen of not less than 1% by weight on a substrate; forming an amorphous thin film including a ferroelectric material on the burnable material film; and oxidizing and crystallizing the amorphous thin film while supplying hydrogen to the amorphous thin film by burning the burnable material film through heating of the burnable material film and the amorphous thin film in an oxygen atmosphere, to thereby form a first ferroelectric film on the substrate.
