Resin seat and falling perpendicularly type back light unit and falling perpendicularly type back light type Liquid Crystal Display

摘要

As for this invention, thickness is 1 - 5mm, multilateral gimlet type, multilateral spindle stand type, conical type, truncated cone type or cutting sphere type concave form is formed in the other hand surface, when the side or the generating line of the said concave form designating the angle which the plane surface where concave form has opened forms as , it is 1040 or 5080 or 4043 or 4750, at the same time regards the resin seat where the below-mentioned condition (1) and (2) suffices at least one inside. (1) the above-mentioned concave form forms the plural line groupsHowever, each line group which forms the plural line groups approaching respectively, consists of the plural lines which exist, each line becomes, plural concave forms lining up in one line, and through the territory where concave form does not exist has adjoined each line group with the other line group (2) convex form of cutting sphere type is formed to the surface which is opposite to the surface where the above-mentioned concave form is formed
