The present invention relates to an imaging device and an imaging method. The object of the present invention is to form, quickly and at low cost, a high-quality image on a medium formed with a curved surface. In order to achieve this object, the imaging device is equipped with: an ink-jet head (2); a pre-curing ultraviolet irradiation device (3); a head unit (4) in which is installed the ink-jet head (2) and the pre-curing ultraviolet irradiation device (3); a medium holding unit (5) that holds a medium (M); a transfer sheet unit holding unit (9) that holds a transfer sheet unit (8), in which a transfer sheet (6) is mounted to a transfer sheet holder (7); an elastic pad unit (10); a final curing ultraviolet irradiation device (11); a cleaning unit (12); and a control unit (13). The ink-jet head (2) applies ink to the transfer sheet (6) and the pad unit (10) pushes the transfer sheet (6) against the medium (M), thus providing a pressure transfer of the ink applied to the transfer sheet (6) to the medium (M).

A light emitting device includes: a substrate; a first light emitting element and a second light emitting element that are mounted above the substrate; and a heat transfer pattern that is formed on the substrate. A rate of decrease in light output with respect to a temperature increase is greater for the second light emitting element than for the first light emitting element. The second light emitting element is mounted above the substrate via the heat transfer pattern, and the first light emitting element is mounted above the substrate without the heat transfer pattern

The invention provides a liquid crystal display device which can restrain color offset of a normally white displayed vertical oriented liquid crystal display device in observation in a left-and-right direction. The liquid crystal display device is provided with a first substrate, a second substrate, a liquid crystal layer, a first polarizing plate, a second polarizing plate, a first optical board, a second optical board and a third optical board. The absorption axes of the polarizing plates are configured approximately perpendicular with one another. Furthermore each polarizing plate is configured at an angle of approximate 45 DEG relative to the orienting direction of an approximately central part in the layer thickness direction of the liquid crystal layer when an electric field is applied. The first optical board is a 1/4 wavelength board, and the in-surface slow axis is configured at an angle of approximate 45 DEG relative to the absorption axis of the first polarizing plate. The second optical board is a 1/4 wavelength board, and the in-surface slow axis is configured at an angle of approximate 45 DEG relative to the absorption axis of the second polarizing plate. The third optical board has negative biaxial optical anisotropy, and the in-surface slow axis is configured to be approximately perpendicular with the absorption axis of the first polarizing plate.

An illumination device and a light-emission module suppressing a change in color temperature when light emitted from a light-emission unit passes through an optical member. The illumination device (3) has a lighting apparatus that includes: a first light-emission part (12a) emitting light of a daylight color temperature; a second light-emission part (12b) emitting light of an incandescent lamp color temperature; and the optical member (50), which is disposed on an optical path of the light emitted from the light-emission parts (12a, 12b). A correlated color temperature of the light emitted from the second light-emission part (12b) is set to 2238 K. Due to this, in a spectrum of the light emitted from the second light-emission part (12b), a maximum intensity within a wavelength range from 400 nm to 500 nm is no greater than one-tenth of a maximum intensity within a wavelength range from 300 nm to 800 nm.
