Abstract
A display panel and a display device includes a high-permittivity material disposed between electrodes of capacitor disposed in a subpixel. This increases the capacitance per area of the capacitor, such that a high-resolution display device is provided. A high-permittivity material is disposed in the insulating layer, and the surface of the insulating layer is planarized by polishing. The high-permittivity material is prevented from residing in any area, except for the area in which the capacitor is disposed. An unnecessary increase in load in the subpixel is prevented, and the capacitance of the capacitor is increased.
