Problems solved by technology

[0008] The inventors of the present invention have ascertained that such near-infrared rays have the potential to adversely affect the transmission of infrared data in a POS (point of sale) computer information system used near a PDP, or when the PDP is used in a television set at home. Occasionally, it may cause misoperation of the near-infrared remote control of household electrical equipment

Embodiment approach

[0047] exist Figure 5 In the PDP device shown in , a display panel 2 and a control section 3 are provided on a front-opening casing 4, and the front of the display panel 2 is protected by a transparent protective plate 1.

[0048] The display panel 2 is constituted, for example, of a surface discharge panel with an AC (alternating current) type three-electrode structure. Such as Image 6 As shown in , the display panel 2 includes a front transparent substrate 21 formed of glass and a rear transparent substrate 22 formed of glass. A plurality of address electrodes 23 are arranged at a predetermined distance, and a strip-shaped protective wall 24 is correspondingly constructed between the address electrodes 23, and correspondingly covering each address electrode 23 is formed on the surface of the back substrate 22 facing the front transparent substrate 21. and the fluorescent layer 25 on the side plane of each partition wall 24 .

[0049] The fluorescent layer 25 is composed...

Abstract

In a flat display device having a pair of substrates for defining a gas discharge space in which a gas used to generate discharge luminance is sealed, means for absorbing or reflecting near infrared rays is included.

Description

[0001] This application is a divisional application of the invention patent application with the filing date of June 11, 1997, the application number of 97105575.0, and the title of the invention being "plane display device". technical field [0002] The present invention relates to flat display devices, and more particularly to flat display devices used in computers, televisions as image displays. Background technique [0003] A plasma display panel (hereinafter referred to as PDP) as a flat display device has been practically used as a display device in, for example, a wall-mounted television. According to different voltage driving systems, PDPs are classified into AC (alternating current) type and DC (direct current) type. In most cases, the display portion of an AC type color PDP has, for example, the structure shown in FIG. 1 . [0004] In FIG. 1 , respective address electrodes 102 and phosphor layers covering these address electrodes 102 are formed on a glass back sub...
