CRT PROJECTING TYPE DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To obtain a CRT projecting type display device of satisfactory contrast by suppressing unnecessary light. SOLUTION: A CRT projecting type display device projects a luminous flux emitted from a CRT fluorescent body layer on a screen via a light absorbing means. Unnecessary light is reduced by a light absorbing means arranged in an optical path until the luminous flux emitted from the CRT fluorescent body layer passes through the non-reflective film of a first projecting lens 2.
