摘要： A backlight device of the present invention includes a substrate (2), a liquid crystal layer (4), and a scattering layer (5). The substrate (2) has a surface facing the liquid crystal layer (4), on which surface two comb electrodes (3a and 3b) are provided. The comb electrode (3a) includes a plurality of comb-teeth parts (33a) meshing with a plurality of comb-teeth parts (33b) of the comb electrode (3b). Therefore, the comb electrodes (3a and 3b) can causes electric fields to be generated, in response to an applied voltage, in at least two directions each parallel to the surface of the substrate (2). Further, there is a region whose effective refractive indexes with respect to polarized light p and polarized light s become large. It is therefore possible to control emission of both the polarized light p and the polarized light s.

摘要： A solar cell module (10) includes: a low refractive index material layer (1) provided on an object (4); a high refractive index material layer (2), provided on the low refractive index material layer (1), which has a higher refractive index than the low refractive index material layer (1); and a solar cell element (3) provided on that surface of the high refractive index material layer (2) which intersects that surface (counter surface facing the low refractive index material layer (1)) of the high refractive index material layer (2) which is in contact with the low refractive index material layer (1). Further, the high refractive index material layer (2) contains a fluorescent material dispersed therein. Thus, light guided through the high refractive index material layer (2) is reflected at the interface between the high refractive index material layer (2) and the low refractive index material layer (1) and the interface between the low refractive index material layer (1) and an air layer, and is efficiently focused onto the solar cell element (3). This makes it possible to inexpensively and easily produce a solar cell module that has a high degree of freedom in design and that can be installed on a curved surface etc. without limitations of installation locations.
