description The present invention provides a polystyrenic resin composition, which has low water absorption, excellent in suppression of product bending or size exchanging, excellent in photo and releasing properties, and suitable for the production of shaped light-guild plate, and a light-guild plate formed from the same. As to the polystyrenic resin composition of the present invention, the polystyrenic resin composition comprises 100 mass by part of styrenic resin and 0.02-0.2 mass by part of phosphoric anti-oxidant, in which the content of 4-t-butylcatechol is 1-6 g per 1g of the styrenic resin.
