Abstract: An electronic device including first to third light emitting regions and a dummy region is provided. The electronic device includes a base layer, and a display element layer including a pixel defining film on the base layer, light emitting elements divided by the pixel defining film, and a reduction preventing layer containing a reduction preventing agent, and the light emitting elements each include an electron transport region containing a metal oxide. The electronic device may have improved electron transport function of the electron transport region by the reduction preventing agent contained in the reduction preventing layer, thereby improving the luminous efficiency.

Abstract: Methods for manufacturing a base film including a printed circuit film are provided. The base film includes a printed circuit film with a tap integrated circuit (“IC”). The method includes forming reference fixing-holes in the base film at both sides of the printed circuit film, respectively, the reference fixing-holes being collinear with a center line of the printed circuit film, and forming a plurality of auxiliary fixing-holes separated from the reference fixing-holes at equal intervals along a longitudinal direction of the base film. The printed circuit film includes a first side parallel to the longitudinal direction of the base film, a second side parallel to the first side, a third side perpendicular to the first and second sides, and a fourth side parallel to the third side. The center line of the printed circuit film is located at the same distance from the third side and the fourth side.
