Title:
IMAGE DISPLAY
Document Type and Number:
Japanese Patent JP3168353
Kind Code:
B2
Abstract:
PURPOSE: To enable super-fine, high-contrast display without causing color shade and brightness irregularity.
CONSTITUTION: A phosphor 5 to which electron beam emitted from an electron emission element 4 is applied is provided on a rear plate 1 and a light absorbing layer 6 is provided on the opposite side of an image display plane (on the whole back side of the rear plate 1). In this way, easy alignment between the electron emission element and the phosphor is ensured and brightness during cut-off is kept lower by the light absorbing layer, resulting in higher contrast.
