摘要
A light-trapping sheet of the present disclosure includes: a light-transmitting sheet; and light-coupling structures arranged in an inner portion of the light-transmitting sheet. The light-coupling structure includes first, second and third light-transmitting layers. A refractive index of the first and second light-transmitting layers is smaller than that of the light-transmitting sheet; and a refractive index of the third light-transmitting layer is larger than those of the first and second light-transmitting layers. The third light-transmitting layer has a diffraction grating parallel to the surfaces of the light-transmitting sheet. The light-trapping sheet further includes a transparent cover sheet opposing at least one of the surfaces of the light-transmitting sheet with a gap interposed therebetween.
