A dial plate is in a disc shape. A pointer body is located at a center of the dial plate and rotational relative to the dial plate. The dial plate has a plurality of grooves extending radially outward from the center. The pointer body is configured to emit light radially outward to illuminate one of the grooves to produce a linear illumination extending linearly outward from the pointer body.

A lighting and colour scheme for instruments to allow an apparent colour change of indicia and background between daylight viewing and night-time viewing when an instrument light is turned on. White indicia on a red background is conspicuous in daytime, but can be transformed to green indicia on black background when the instrument is illuminated with a green LED for night-time viewing.

A dial plate is provided with a mark layer having translucency, the mark layer including numbers of linear grooves formed on a surface of the mark layer, and a reflective layer that is arranged on a back face side of the mark layer, and reflects light incident from the mark layer side. The reflective layer includes a light transmission area that allows the light emitted from a light source arranged on the back face side to transmit therethrough to a front face side, and displays a display design by the light transmitting through the light transmission area when the light source is turned on. In the reflective layer, at least the light transmission area is composed of pearl ink.

A display apparatus includes: a substrate having a first surface; a light source that is disposed to the first surface of the substrate; a display plate that is disposed adjacent to the first surface of the substrate; and a light block body that surrounds the light source between the substrate and the display plate. The light source includes a light source body that emits light, a light source base material that has a mount surface, the light source body being mounted to the mount surface, and a mold portion that transmits the light and covers a circumference of the light source body on the mount surface of the light source base material. The mount surface is positioned closer to the display plate than an end face of the light block body, the end face being adjacent to the substrate.

A pointer is rotational relative to the dial plate. The pointer includes a pointer shaft, which is non-opaque to conduct light therethrough. A driver unit includes a drive shaft coaxial with the pointer shaft. A light source emits light. A hub interconnects the pointer shaft with the drive shaft. The hub includes a light pickup, which is non-opaque to receive light from the light source and to conduct the light into the pointer shaft.
