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.
