    摘要： In a display device according to a first aspect of the invention, luminance is not made substantially uniform over the entire display screen but rather imparted a luminance gradient such that luminance substantially monotonously decreases from the center of the screen towards the peripheral portion using a luminance gradient forming means, whereby power consumption is reduced compared to cases in which the entire screen shows substantially uniform luminance. In a second aspect of the invention, by optimizing gray level characteristics and thereby improving a viewer's impression of brightness, luminance gradient is made even less perceivable without increasing power consumption. These configurations provide large screen, low power consumption display devices.

    摘要： The present invention aims at realizing a PDP and a mercury-free fluorescent lamp feasible to maintain excellent luminescent characteristics over long periods by suppressing time-lapse changes in luminescent characteristics of a phosphor that is excited by vacuum ultraviolet light to thereby emit light. To accomplish this object, the oxide phosphor of the invention comprises individual particles, each of which has a region at and near the surface thereof modified, and the elemental composition of the surface region is in a more oxidized state than that of the internal region of the particles. Alternatively, the surface region has more halogen or chalcogen in the elemental composition. In the phosphor treatment method of the invention, the surface region of individual phosphor particles is selectively modified by (i) forming a highly reactive gas atmosphere by exciting gas which contains reactive gas, and (ii) exposing the phosphor to the gas atmosphere.
