Abstract
PURPOSE: To obtain a high-precision and high-performance color electron gun formation by forming plural U-shaped grooves in plural prescribed positions on the external face and inserting and fixing a reference supporter element to each groove.
CONSTITUTION: Plural U-shaped grooves 31 are formed in plural prescribed positions on the external face, and reference supporter element 50 is inserted and fixed to each groove. As a result, inter-electrode non-co-axis, parallel error, curve, torsion, inclination, etc., are prevented to prevent the lowering of the vacuum degree.
