  • Patent number: 9269756
    Abstract: An organic light emitting display apparatus capable of reducing a dead space for arranging wirings in a panel. The organic light emitting display apparatus includes: a panel including a screen portion on which images are displayed and a non-screen portion surrounding the screen portion; a first wiring portion and a second wiring portion formed on different locations of the non-screen portion to be connected to pixel wirings on the screen portion; and a film substrate including a plurality of connection portions connected to the first wiring portion and the second wiring portion. Thus, the dead space that is formed on the non-screen portion of the panel for forming the wirings may be effectively reduced.
