    摘要: An optical filter is provided on the output side of light from plural kinds of cells that output light with colors different from one another. In the optical filter, the penetrable rate of at least a portion of the wavelength band of light output from the cell with the color having highest luminescent intensity is set lower than that of the wavelength band of other kinds of cells. Consequently, the reflectance rate of outer light incident to a display can be reduced. Particularly, in a room environment using artificial lighting, the reflectance rate of outer light can be reduced in the wavelength band of light with relatively high luminescent intensity. Resultingly, bright room contrast can be improved by suppressing the reflection of outer light. Since the penetrable rate of the color with the highest luminescent intensity is reduced, reduction in brightness of the display can be kept to a minimum.

    摘要: A plasma display panel has a front substrate (3) and a back substrate (2) arranged opposed to each other through a discharge space (4). On the back substrate, a fluorescent layer (5) is formed. On the front substrate, display electrodes are formed extending in a horizontal direction, a discharge cell area is demarcated corresponding to the display electrodes, and a plurality of shielding films (13) extending in the horizontal direction are moreover formed at each position which is among the display electrodes and within the discharge cell area. When the distance between the shielding films and the fluorescent layer is set to be D, the width L of a shielding film and the distance S between the shielding films satisfy 0.58≦L≦D and D≦S≦1.73D. This reduces the reflectance ratio of outdoor daylight to improve lighted room contrast.
