Abstract

Se proporciona una hoja de reflexion, utilizando una película de baja rigidez, más delgada, para usarse para rodear una lámpara fluorescente del tipo de tubo recto en un dispositivo de contraluz de panel de pantalla de cristal líquido, del tipo de borde, cuya hoja de reflexion puede realizar una más alta brillantez del dispositivo de contraluz. Una hoja de reflexion que comprende: un soporte de película que tiene un espesor de 25 a 50 æm y, aplicando sobre una superficie de soporte, un recubrimiento de pintura reflectora comprendiendo de una mezcla de un aglutinante de resina de un copolímero de (met)acrilato con un globo de partícula pequeña que tiene un diámetro de partícula de 0.05 a 10 æm y una proporcion del diámetro interno vacío al diámetro de partícula de 0.2 a 0.9.
