Illumination apparatus and display apparatus

摘要

[Object] To provide an illumination apparatus capable of reducing a view angle dependency of a chromaticity distribution in a light-emitting surface of a phosphor layer. [Solving Means] A light beam control device (11) that controls emitted light from light-emitting diodes (10) so that a view angle dependency of a chromaticity distribution in a light-emitting surface (22a) of a phosphor layer (22) is suppressed is interposed between the light-emitting diodes (10) and the phosphor layer (22). The light beam control device (11) causes the emitted light from the light-emitting diodes (10) to be bent in a vertical direction or an approximately-vertical direction with respect to the light-emitting surface (22a) of the phosphor layer (22) and thus causes the light to enter the phosphor layer (22). As a result, light that obliquely enters a surface of the phosphor layer (22) is lessened, and the view angle dependency of the chromaticity distribution in the light-emitting surface (22a) of the phosphor layer (22) is reduced.
