Abstract
Se provee una película óptica que puede proveeré brillo favorable para la dirección frontal y propiedad de difusión de la luz sin el uso de una lámina de prisma, ni de una lámina de lente. Se sobreponen dos estructuras laminadas, cada una de las cuales es producida proveyendo una capa 12 difusora de la luz, formada de partículas de resina acrílica y un aglutinante de resina de copolímero de estireno-acrílico sobre un soporte transparente 11, para constituir una película óptica 1. El aglutinante de resina de copolímero de estireno-acrílico tiene de preferencia una temperatura de transición de vidrio de 40 ºC o más. La capa difusora de la luz 12 contiene de preferencia un aglutinante de resina acrílica que tiene una temperatura de transición de vidrio de 30 ºC o menos.
