(57) [Problem] To provide a light guide plate which is good in appearance, has high luminance, has little unevenness in luminance, and has excellent mechanical strength, and a method for manufacturing the same. The proportion of a repeating unit having an alicyclic structure in a main chain or a side chain in all repeating units of a polymer is 50 to 50. 100 mol%, 280 ° C., load 2.1 The melt flow rate measured according to JIS-K-6719 at 6 kgf is 20 to 300 g / 10 min. Consisting of an alicyclic structure-containing thermoplastic resin. The alicyclic structure-containing thermoplastic resin is preferably a hydrogenated norbornene ring-opening polymer. |
