PURPOSE:To improve the relative positioning precision by arranging one positioning pin at one end horizontally and in the center vertically and by arranging the other positioning pin at the opposite end horizontally and at one end vertically in arranging positioning pins. CONSTITUTION:One positioning pin is arranged at the left center point Q1, i.e., near the left end of an electrode 14 horizontally and near the center of the electrode 14 vertically, and the other positioning pin is arranged at the right lower point Q2, i.e., near the right end horizontally and near the end vertically. In addition, the difference between diameters of the positioning pin and positioning hole at the Q1 point is made small, thereby the positioning precision at the screen center portion can be improved. |
