摘要： In a long-gap discharge using a trigger discharge in a display cell of a PDP having three electrodes (X, Y, A), a technology capable of stably generating the trigger discharge with low power consumption by using a float electrode is provided. In a dielectric layer of the PDP, a long gap is formed between first and second display electrodes, first and second float electrodes which are capacitive-coupled to the first and second display electrodes are formed, and a short gap is formed between the first and second float electrodes. A sustain pulse is applied to the first and second display electrodes, thereby generating a small trigger discharge in the short gap. Subsequently to this discharge, a main discharge at the long gap is generated. Electrodes and capacitances are structured so that the main discharge has an intensity equal to or smaller than one-fifth of an intensity of the trigger discharge.

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.
