    Abstract: A display device includes a base layer, a first pixel transistor, a first gate line, a first data line electrically connected to the first pixel transistor, a first pixel electrode electrically connected to the first pixel transistor and overlapping the first data line in a plan view, and a porous layer. The porous layer is disposed between the first data line and the first pixel electrode and includes a matrix including a polymer resin and a plurality of void portions defined in the matrix. The display device is capable of displaying a sharp image because the porous layer alleviates or prevents a crosstalk between the first data line and the first pixel electrode.

    Abstract: Provided is a display device. The display device includes a liquid crystal display panel and an optical film disposed above the liquid crystal display panel, the optical film comprising a first pattern layer having a first refractive index and a second pattern layer having a second refractive index different from the first refractive index and disposed on the first pattern layer. The first pattern layer includes a first base part and a plurality of first protrusions. Each of the first protrusions includes a bottom surface adjacent to the first base part, an upper surface facing the bottom surface, and side surfaces between the bottom surface and the upper surface. Each of the side surfaces is perpendicular to the bottom surface and the upper surface.
