摘要: A display panel includes a first substrate which includes a display device and a second substrate which is disposed on the first substrate. The second substrate covers a base layer, a color filter layer, a first sealing layer, a color control layer, a step compensating layer, and a second sealing layer. The base layer includes a display area and a non-display area adjacent to the display area. The color filter layer overlaps the display area in a plan view, and is disposed under the base layer. The first sealing layer covers the color filter layer. The color control layer overlaps the display area in the plan view, and is disposed under the first sealing layer. The step compensating layer overlaps the non-display area in the plan view, and is disposed under the base layer. The second sealing layer covers the color control layer and the step compensating layer.
