CONDENSING MEMBER, MATHOD OF MANUFACTURING THEREOF AND DISPLAY APPARATUS HAVING THE SAME

摘要

A condensing member, a manufacturing method thereof and a display device having the same are provided to reduce the manufacturing cost by means of only one condensing member. A condensing layer(420) is formed on the upper surface of a base layer(410) and has a condensing pattern. A lower surface treatment layer(430) is formed at the lower surface of the base layer and includes a round shape of protrusion(432). The protrusion has the ratio of height to width of 0.01 to 0.06. The height of the protrusion has the range of 1 to 10 micrometer. The protrusions are formed regularly at the lower surface of the base layer with the density of the number 4.5 to 10 per 10000 mum^2. The base layer, condensing layer and lower surface layer are constructed by any one of PET(Polyethylene Terephthalate) or PC(Polycarbonate).
