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.
