Abstract
PURPOSE: To enable the white colar curent ratio to change by exposing one or more rows of three colors of fluorescent elements with the light passing through a hole row different from the one in the longitudinal direction to be used for exciting luminescence in operation.
CONSTITUTION: The positions b and r of a linear light source 6 at the exposure of fluorescent elements B and R is replaced with each other around another position g and the distances between the positions g and b and between the positions r and g are set twice as large as the distance S. When exposure is carried out on the photo resistive film 4 under this condition, no change occurs in the exposure of the fluorescent element G whereas the exposure is carried out with respect to the fluorecent elements B and R by the light passing through a row of holes 7 in the longitudinal direction of a slot type shadow mask 5. With respect to the outer rows of holes 7 the exposure is displaced by a half pitch, by which the hole row in the longitudinal direction is displaced from the row through which the light passes in the exposure of the fluorescent element G.
