LIGHT DIFFUSER PLATE WITH LIGHT-COLLECTING LAYER, SURFACE LIGHT SOURCE DEVICE AND LIQUID CRYSTAL DISPLAY DEVICE.

摘要

The present invention provides a light diffuser plate with a light-collecting layer, which can be sufficiently prevented from flawing and which can ensure a sufficient luminance in a front direction. A light diffuser plate 3 with a light-collecting layer, of the present invention, comprises a light-diffusing substrate 31 and a light-collecting sheet 32 which are disposed in a stacked state and are united at their peripheral portions so that an air layer 33 is formed between the light-diffusing substrate 31 and the light-collecting sheet 32.
