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： To provide a projection type video display capable of reliably preventing a double image from being produced. A first light flux producer for producing a first light flux and a second light flux producer for producing a second light flux are arranged on the light emission side of a lamp. The light flux producer comprises a condenser lens, a rod integrator, and a pair of lenses. Lights passing through the pair of lenses are respectively refracted by condenser lenses, and are respectively introduced into first and second areas of a liquid crystal display panel in such a manner as to cross an optical surface in a color separating and mixing sector.
