Abstract
An electrowetting display panel includes a plurality of subpixels. Each of the plurality of subpixels having a subpixel area and an hater-subpixel area. The electrowetting display panel includes a first substrate, including a first insulating layer, a first electrode layer on the first insulating layer, and a first lyophobic layer on a side of the first electrode layer away from the first insulating layer; a second substrate facing the first substrate, including a second electrode layer, and a second lyophobic layer on the second electrode layer; and a plurality of sealing elements between the first substrate and the second substrate to define a plurality of fluid channels, each of the plurality of sealing elements being in the inter-subpixel area. The electrowetting display panel includes a first fluid reservoir and a respective one of the plurality of fluid channels between the first lyophobic layer and the second lyophobic layer.
