Abstract

PURPOSE:To obtain a clear and noiseless picture image with a simple work process by fixing and smoothing a metal back layer and forming a stripe for detecting index signals with the so-called drive process. CONSTITUTION:The red, green and blue fluorescent stripes 2R, 2G and 2B, filming film 3 and metal back layer 4 are formed inside the face panel 1. Then the sensitive thin layer 10 is formed and light is irradiated on it. This layer is characterized by waterproofness and the metal back layer 4 is solidified, then the surface is smoothed. Subsequently, the sensitive thin layer 11 is formed and the shadow mask 12 is mounted and is exposed. Powder 16 for detecting index signals is coated on the sensitive thin layer 11. After that, the sensitive thin layers 11 and 11 are removed with the sintering process and the stripe 16a for detecting index signals is formed.
