A display including a first substrate, a second substrate and spacers is provided. The first substrate includes a first base body, a device structure, an insulating layer, a pixel electrode layer and a planarization layer. The device structure is formed on the first base body. The insulating layer is formed on the device structure, and has at least one through hole. The pixel electrode layer is formed on the insulating layer. A portion of the pixel electrode layer extends into the through hole and electrically connects to the device structure. The pixel electrode layer forms a concave portion corresponding to the through hole. The planarization layer is formed on the pixel electrode layer and filled into the concave portion. The second substrate is disposed opposite to the first substrate. The spacers are disposed between the first substrate and the second substrate, and are correspondingly disposed on the planarization layer.
