Claim:
1. A display panel, having an active region and a peripheral region, comprising: an active device array substrate, comprising: a first substrate; and an active device array layer disposed on the first substrate; a color filter substrate, comprising: a second substrate disposed opposite to the first substrate; a black matrix layer disposed on the second substrate; an overcoat layer disposed on the black matrix layer; and a color filter layer located between the black matrix layer and the overcoat layer, the color filter layer comprising a plurality of color filter patterns disposed in the active region and a plurality of dummy color filter patterns disposed in the peripheral region and overlapped with the black matrix layer, wherein the plurality of color filter patterns and the plurality of dummy color filter patterns define a plurality of blank areas outside areas of the plurality of color filter patterns and the plurality of dummy color filter patterns, at least part of the plurality of blank areas is arranged in a first direction, the plurality of blank areas comprises a plurality of first blank areas in the active region and a plurality of second blank areas in the peripheral region, and the plurality of first blank area has a width different from at least one of the plurality of second blank areas in the first direction; a plurality of spacers disposed on the color filter substrate and a portion of the plurality of spacers propping against the active device array substrate, wherein the plurality of spacers comprises a plurality of first spacers and a plurality of second spacers, and a height of the plurality of first spacers is smaller than a height of the plurality of second spacers, at least part of the plurality of first spacers is located in the active region and at least part of the plurality of first spacers is located in the peripheral region, at least part of the plurality of second spacers is located in the active region and at least part of the plurality of second spacers is located in the peripheral region, the at least part of the plurality of first spacers in the peripheral region is disposed over the plurality of dummy color filter patterns, the at least part of the plurality of second spacers in the peripheral region is disposed within the plurality of second blank areas, and the plurality of first spacers is separated from the plurality of second spacers; and a display medium located between the active device array substrate and the color filter substrate, wherein the at least part of the plurality of second spacers in the peripheral region keeps a distance from the active device array layer, the at least part of the plurality of second spacers in the active region contacts the active device array layer, the at least part of the plurality of first spacers in the peripheral region contacts the active device array substrate, and the at least part of the plurality of first spacers in the active region keeps a distance from the active device array substrate.
