Filed: 2004-02-09
Abstract: <P>PROBLEM TO BE SOLVED: To provide a front panel which can increase a light-room contrast and reduce deterioration in picture quality and a decrease in contrast due to inter-pixel crosstalk and stray light when combined with a display panel which emits output light having no directivity or broad directivity, and a display device using the same.  <P>SOLUTION: Acicular light guide bodies in a shape of a frustum of a cone are stood in large numbers; and the output light of a display element is propagated by total reflection in the acicular light guide bodies and external light is repeatedly reflected on a surface forming a wedge surface to attenuate. Further, when light absorbing film is coated on the surface of acicular light guide bodies, a contrast ratio is made large. With this structure, a high contrast is obtained in a light room, the acicular light guide bodies stood in large numbers are made long, and light incidence surfaces of the acicular light guide bodies are brought into contact with a display panel display surface to reduce crosstalk between adjacent pixels, thereby reducing a decrease in contrast due to display light.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
