Abstract:
1. A light-emitting tube array display device comprising: a light-emitting tube array constituted of a plurality of light-emitting tubes arranged in parallel with discharge gas filled therein; a light-transmitting supporter abutting a display surface side of the light-emitting tube array for supporting the light-emitting tube array and having electrodes, crossing the light emitting tubes and formed on a surface of the supporter facing the light-emitting tube array, for applying a voltage to the light-emitting tubes; a phosphor layer formed on a rear side inner wall of each light-emitting tube; a light-transmitting adhesive layer formed between the supporter and the light-emitting tube array; a rear side substrate abutting a surface of each light-emitting tube so that the light-emitting tube array is held between the supporter and the rear side substrate; electrodes formed on a surface of the rear side substrate facing the light-emitting tubes and extending in a direction crossing the electrodes formed on the surface of the supporter; and a resin layer filled into a space formed by display surface sides of adjacent light-emitting tubes and the supporter, to thereby eliminate total internal reflection of light emitted from the adjacent light-emitting tubes into the space that would occur due to air that would be in the space if the resin layer was not filled into the space, wherein the adhesive layer has a refractive index equal to or higher than that of a tube body of each light-emitting tube.
