表示パターンの視認性を向上させたことを特徴とする。In the conventional flat-emitting type fluorescent display panel described above, the display is observed from the translucent anode substrate side.
The wiring pattern formed by the J mesography method is also visible from the observation surface, and there is a drawback that the visibility of the display is impaired due to reflection of the wiring pattern. To compensate for this drawback, a method is usually used in which the display is observed through a color filter placed on the display side of the fluorescent display panel. Although this method improves visibility to some extent, the display brightness [Means for solving the problem] The fluorescent display panel of the present invention is a flat-emitting type fluorescent display panel in which a display consisting of luminescence of a fluorescent substance is observed from the side of a transparent quadrupole substrate. In an optical display panel, a light-transmitting insulating film made of colorless low-point glass is provided on a light-transmitting anode substrate, and a wiring pattern made of A1 or the like is further formed on this insulating film. It is characterized by suppressing reflection due to the metallic luster of the wiring pattern by the action of fine irregularities on the surface, improving the visibility of the display pattern without causing a decrease in brightness.
