Electron gun used in in-line type color CRT and color CRT using the same

摘要

According to the present invention, there is provided an in-line type color CRT electron gun (26) comprising a triode (28a, 28b, 28c, 31, 32) and a plurality of grids (33, 34, 35, 36), characterized in that at least one of the plurality of grids (33, 34, 35, 36) is made of a black member or a member on which a black film is formed. According to the present inven­tion, the time required for attaining a stable tem­perature of the member is reduced, thereby improving deviations in static convergence and reducing the time required for an image to be normally displayed.
