摘要:
The present invention relates to a cathode ray tube suitable for use with a flat type cathode ray tube in which a material from which a secondary electron is emitted by the impingement of an electron beam is exposed on a surface of an area of a first panel portion (2) having on its inner surface formed a phosphor screen on which the electron beam from an electron gun impinges and an insulative material which forms a second panel portion (3) is exposed on an inner surface of the second panel portion (3) opposing the first panel portion (2) wherein the secondary electron is accumulated to present a predetermined high potential state so that an electric field is prevented from being disturbed in a path of the electron beam.

The lighting unit includes the DMDs (80R), (80G), and (80B). The lighting unit also includes: the prisms (50) and (60) combining the light emitted from the DMDs (80R), (80G), and (80B); and the light modulating optical device (90G). The incident light including the green component light and the yellow component light enters the light modulating optical device (90G). The light modulating optical device (90G) transmits the green component light and changes a transmittance of the yellow component light depending on a change of a molecular state. Light having emitted from the light modulating optical device (90G) enters the DMD (80G), which corresponds to the incident light.

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).

An illuminating apparatus comprises a light source and an optical system for guiding the light from the light source to an imager such as a liquid crystal panel. The optical system has an optical element disposed for changing a traveling direction of the light traveling to the imager in accordance with a control signal. The optical element is controlled such that, out of all pixel regions on the imager, part of the light amount to be applied to low-brightness pixel regions is distributed to high-brightness pixel regions.
