A filter may include a base film and multiple color pattern units included in the base film. The filter may also include a front pattern layer containing multiple color pattern units, where widths of cross sections of the color pattern units may be greater in parts oriented toward a front of the front pattern layer than in parts oriented toward a rear of the front pattern layer, and a rear pattern layer may be on the rear side of the front pattern layer, and the rear pattern layer may include multiple color pattern units, where widths of cross sections of the color pattern units may be greater in parts oriented toward a rear of the rear pattern layer than in parts oriented toward a front of the rear pattern layer, and a plasma display panel using the filter.
