## Abstract

A display device and a method for manufacturing the same are provided. The display device includes a first substrate, a second substrate and a light curable sealant. The first substrate has a displaying area and a non-displaying area, in which the displaying area includes a pixel array, and the non-displaying area includes a driving circuit. The driving circuit includes at least a capacitor which is made of transparent conductive material. The second substrate has an opaque area. The light curable sealant is located between the first substrate and the second substrate. When viewing from a normal vector of the first substrate or the second substrate, the light curable sealant, the capacitor and the opaque area are at least partially overlapped with each other.
