Title (EN) LIGHT DIFFUSION PLATE
(FR) PLAQUE DE DIFFUSION DE LUMIÈRE
(JA) 光拡散板
Abstract:
(EN) The objective of the present invention is to provide a light diffusion plate used in a direct backlight unit, the light diffusion plate: having high heat resistance, light resistance, and water resistance; exhibiting excellent rigidity and display quality; and being suitable for designing thinner plates, narrower bezels, and increased size. A light diffusion plate provided with a glass plate having a first main surface and a second main surface, the heat expansion coefficient of the glass plate being -100×10-7 to 500×10-7/°C, a light dispersion film that includes a matrix and particles being provided on at least one main surface of the glass substrate, the matrix including an organic-inorganic composite compound, the particles being inorganic oxide particles having a lower refractive index than the refractive index of the matrix, and light incident on the first main surface being transmitted from the second main surface while being diffused.
(FR) L'objectif de la présente invention est de fournir une plaque de diffusion de lumière utilisée dans une unité de rétroéclairage direct, la plaque de diffusion de lumière : ayant une résistance thermique, une résistance à la lumière, et une résistance à l'eau élevées ; présentant une rigidité et une qualité d'affichage excellentes ; et étant appropriée pour concevoir des plaques plus minces, des cadres plus étroits et une taille accrue. Une plaque de diffusion de lumière comprend une plaque de verre ayant une première surface principale et une seconde surface principale, le coefficient de dilatation thermique de la plaque de verre étant de -100×10-7 à 500×10-7/°C, un film de dispersion de lumière qui comprend une matrice et des particules étant disposé sur au moins une surface principale du substrat de verre, la matrice comprenant un composé composite organique-inorganique, les particules étant des particules d'oxyde inorganique ayant un indice de réfraction inférieur à l'indice de réfraction de la matrice, et la lumière incidente sur la première surface principale étant transmise à partir de la seconde surface principale tout en étant diffusée.
(JA) 耐熱性、耐光性および耐水性が高く、優れた剛性、表示品質を示す、薄板化、狭額縁化、大型化に適した直下型バックライトユニットに使用される光拡散板を提供することを目的とする。 第一の主面と第二の主面とを有するガラス板を備え、該ガラス板の熱膨張係数が-100×10-7~500×10-7/℃であり、前記ガラス基板の少なくとも一つの主面にマトリックスと粒子とを含む光散乱膜が設けられ、前記マトリックスは有機無機複合化合物を含み、前記粒子は、屈折率が前記マトリックスの屈折率より小さい無機酸化物粒子であり、前記第一の主面への入射光を拡散させながら前記第二の主面から透過させる光拡散板。
