摘要： An LED light source is formed of an LED and an angle control lens. The angle control lens includes a transparent member in a shape of a rotational symmetry, and includes a center convex curved surface area (light-emission area) A1, a peripheral curved surface area (light-emission area) B1, a peripheral curved surface reflection area C1, a center concave curved surface area (light-incidence area) D, and a convex curved surface area E formed between the areas A1, B1. The convex curved surface area E is formed in a position for receiving direct incoming light from the LED (direct incoming light deviated from the center portion), and is optically constructed to anteriorly emit this received light (in a direction intended to be emitted as a result of a light-emission angle being controlled).

摘要： A reflection mixing member (13) has an alignment in which light from a first light source is incident on a reflecting surface (13a) and light from a second light source is incident on a reflecting surface (13b). A relationship between a pitch Wp, which is a pitch between portions (triangular prisms) respectively formed of the reflecting surface (13a) and the reflecting surface (13b) in the reflection mixing member (13), and a lens pitch Wf is set to be (Wp/Wf≠1). As a result, light fluxes of respectively different distribution are incident on each lens portion of fly's eye lens 14a, so that it is possible to prevent luminance non-uniformity in light incident on a liquid crystal display panel (5) from being generated and prevent color non-uniformity from being generated on a screen at the same time.
