| abstract | An optical film obtained by an extrusion method having excellent productivity and having very high thickness accuracy is provided. A direction facing the lip edge opposite to the resin discharge direction of the T die used for extrusion molding is 0 °, and a direction perpendicular to the resin discharge direction and the land surface 2c of the T die and facing the lip edge is 90 °. The average value of the lip edge bright line width A facing from the 45 ° direction is 50 μm or less, and the bright line width difference facing from the three directions of 30 °, 45 °, and 60 ° is 2 μm / mm in the width direction of the T die. 5 mm or less, obtained by extrusion molding, an unstretched film, made of an amorphous thermoplastic resin, an average thickness R of 200 μm or less, and a thickness unevenness in the width direction of 2.5 × 10 −3. An optical film having a size of R μm / 5 mm or less. [Selection] Figure 2 |
