LIGHTGUIDE MEMBER AND LIQUID CRYSTAL DISPLAY DEVICE PROVIDED WITH THE LIGHTGUIDE MEMBER

PROBLEM TO BE SOLVED: To realize a lightguide member and a liquid crystal display device as a surface light source having high luminance and homogenization. SOLUTION: A thickness H between a reflecting face 3 and an irradiating face 4 is made smaller according as it goes farther away from an inciden...

Zusammenfassung:	PROBLEM TO BE SOLVED: To realize a lightguide member and a liquid crystal display device as a surface light source having high luminance and homogenization. SOLUTION: A thickness H between a reflecting face 3 and an irradiating face 4 is made smaller according as it goes farther away from an incident face 2 against a first direction Y facing an end face 6 opposed to the incident face 2 and is made smaller according as it approaches closer to each of end faces 7, 8 against a second direction X crossing nearly perpendicularly to the first direction Y and a thickness direction Z.
