Problems solved by technology

[0012] As described above, in the prior art flat display device, the front color filter (panel protection plate) disposed on the front side of the flat display panel is formed by affixing a film for preventing external light reflection or (capable of It is formed by blocking the electromagnetic waves and infrared rays from the flat display panel, so its price is very high, which has caused a problem of rising product prices of flat display devices.

Embodiment Construction

[0024] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0025] image 3 is a side sectional view showing a first embodiment according to the present invention.

[0026] However, in image 3 in, with figure 1 Parts of the same construction as the existing installation shown will be used with the figure 1 represented by the same symbol.

[0027] The flat display panel 3 of the flat display device of the present embodiment is formed by an elastic layer 14 made of a foam material such as foam rubber (capable of absorbing deformation due to heat generation and installation of the device and having a hardness below 30°). Supported on chassis 2. Here, the optical color filter 17 is pasted on the display side surface of the flat display panel 3 as a protective layer.

[0028] Such as Figure 4 As shown, the optical color filter 17 is formed by forming an infrared absorption / color tone correcti...

Abstract

A flat display apparatus is provided with a flat display panel, which is characterized in that an optical filter is attached to the display screen surface of the flat display panel of the flat display apparatus, and the optical filter is constituted of a lamination of an electromagnetic-wave blocking sheet, an infrared-radiation absorbing and color-tone correcting sheet and an ambient light antireflective sheet. The electromagnetic-wave blocking sheet is formed by being adhering to the display screen surface of the flat display panel at the side of the flat display panel. Therefore the outer peripheral edge of the electromagnetic-wave blocking sheet projects beyond the outer periphery of the infrared-radiation absorbing and color-tone correcting sheet and ambient light antireflective sheet. Thus, an earth connection part is formed by means of the projecting part, and spot marks for locating is formed on a black overlay film covering the earth connection part.

Description

[0001] This application is a divisional application of an invention patent application with an application date of December 10, 2003, an application number of 200310117294.8, and an invention title of "flat display device". technical field [0002] The invention relates to the composition of a flat panel display device. Background technique [0003] The flat display device includes a thin flat display panel such as a plasma display panel (PDP) or a field emission display panel (FED). [0004] The PDP includes a front substrate and a rear substrate, which are arranged parallel to and facing each other, and the periphery of the discharge space formed between them is sealed. [0005] The inner surface of the front substrate of the reflective AC PDP is formed with several row electrode pairs for surface discharge (display discharge) and the dielectric layer covering these row electrode pairs, while the inner surface of the back substrate facing the front substrate Column electr...
