摘要： 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.

摘要： A foldable display device includes a display panel configured to be folded around a folding axis. The display panel includes spacers disposed in a non-folding area and a folding area, and the spacers may have different sizes or densities. Dimensions of the spacers may be in a direction of the folding axis or intersect the direction of the folding axis. The display panel also includes pixels in an active area that overlap with the spacers, which may help reduce peeling, cracking, defects, or reduction in pixel brightness due to folding of the display device.
