Abstract
Disclosed herein is a light-diffusing film having pores for use in a backlight unit of a TFT-LCD. The light-diffusing film having pores of this invention comprises a base sheet composed of a synthetic resin; a light-diffusing layer laminated on one surface of the base sheet and having pores formed by applying a composition including a light-diffusing resin and light-diffusing particles contained in the light-diffusing resin under controlled composition supply pressure of 1˜5 kgf/cmand travel speed of the base sheet of 10˜200 m/min; and an antiblocking layer laminated on the other surface of the base sheet. According to this invention, the light-diffusing film has improved total light transmittance and light diffusibility owing to the pores formed in the light-diffusing layer, and is thus usefully applicable to a backlight unit of a TFT-LCD.
