Method of forming metal back-attached fluorescent surface and image display unit |
摘要 |
A method for forming a metal back-attached phosphor screen comprises the step of dissolving/removing or rendering highly resistant a specified area of a metal film formed on a phosphor screen by using a liquid that dissolves or oxidizes the metal film. After part of a metal film is removed or rendered highly resistant, an insulating or highly resistant inorganic material may be applied to the remaining ends thereof. Alternatively, an insulating or highly-resistant inorganic material may be added to a dissolving or oxidizing liquid to dissolve/remove or render highly resistant a metal film, and at the same time ends of the metal film are coated with the inorganic material. In this metal back-attached phosphor screen, electron emission elements and the phosphor screen are protected against destruction/deterioration by discharging.
