【Task】 A light diffuser that not only makes light emitted from a light source uniform, but also improves light utilization efficiency, and improves productivity by thinning, integration, and member saving, and a method for manufacturing the same, and the light diffuser Provided are a surface light-emitting device, a display device, and a lighting device using the above. [Solution] A light diffuser comprising a foam diffused by application of radiation energy and thermal energy, comprising a light diffusion portion having a predetermined distribution pattern of bubble density, It is preferable that the bubble occupation area ratio of the foam is distributed in a range of 65% or less, It is preferable that the light diffusing portion has a low foaming area in which a bubble occupation area ratio is 0.5% or less and a high foaming area in which the ratio is 1% or more.
