Description of the Invention: [Technical Field] The present invention relates to a composite concentrating sheet having diffusing particles, and more particularly to a concentrating sheet applied to a liquid crystal display. A curved prism unit mixed with a plurality of diffusing particles to provide a composite concentrating sheet with both diffusion and concentrating effects. [Prior Art] Conventional concentrating sheet, as shown in Figures i and 2, discloses a concentrating sheet 9 comprising a substrate 91 and a plurality of prism units 92 arranged in parallel with one of the substrates 91. On the first surface. The prism unit 92 is composed of two inclined faces for refracting light to cause a condensing phenomenon. For example, when a light ray 93 is incident on the substrate 91 at a relatively large incident angle with respect to the second surface of the substrate 91 (that is, the light ray 93 is less perpendicular to the second surface of the substrate 91), the light ray 93 The prism unit 92 that emits the first surface of the substrate 91 can be smoothly refracted. However, when a light ray 94 is incident on the substrate 91 at a small incident angle (less than 6 to 9 Å) with respect to a second surface of the substrate 91 (that is, the ray 94 is perpendicular to the substrate 91) The light ray 94 is not refracted to emit the prism unit 92. Instead, the second surface of the substrate 91 is again emitted by total reflection, thereby reducing the primary penetration efficiency of the light 94 and increasing the light loss rate.
