发明名称 Illumination apparatus and liquid crystal display apparatus
摘要 Provided is an illumination apparatus for a liquid crystal display apparatus having a plurality of transmission parts arranged two-dimensionally, having a plurality of aspherical lenses, which is installed in response to each of a plurality of the transmission parts and concentrates light for each of a plurality of the transmission parts; a plurality of light emission parts R1 installed in response to each focal point position of a plurality of the aspherical lenses; and an electroluminescence layer containing a non-light emission region R2 installed between a plurality of the light emission parts R1 themselves. Each of a plurality of the aspherical lenses has an inner side lens face containing an intersection with an optical axis AX, and an outer side lens face enclosing said inner side lens face, and curvature in the outer side lens face is smaller than curvature in the inner side lens face.
