Abstract: Disclosed are an antenna-integrated polarizer and a flexible display device using the same. Shading lines are provided in an active area, and an antenna pattern is provided in a dead area, which surrounds the active area, so as to be electrically connected to the shading lines. Consequently, the reception area of the antenna is increased, and the thicknesses of the antenna and the polarizer are reduced, thereby minimizing folding-resistant force and improving the reliability of the device.
