NEON SIGN DEVICE HAVING PLAIN SHAPE AND METHOD FOR MANUFACTURING THE SAME

摘要

The present invention relates to a neon sign device having a plain shape. The neon sign device having the plain shape according to the present invention comprises an upper glass sheet having electric discharge electrodes installed on its bottom surface; and a lower glass sheet attached closely to the bottom surface of the upper glass sheet and having an electric discharge space where an advertisement pattern to be represented is formed into a cavity. The neon sign device is generally made by bonding the upper and lower glass sheets after forming the electric discharge electrodes and the cavity in the upper and lower glass sheets, respectively. A fluorescent layer is also formed inside the cavity, and inert electric discharge gas is filled inside the cavity. For example, the cavity is formed by engraving it on a portion of a top surface of the lower glass sheet.
