A display device for a vehicle includes: an irradiation unit configured to irradiate a display light for an occupant of the vehicle to display an image; and a storage unit housing the irradiation unit so as to expose a display screen to which the display light is irradiated. The storage unit has an air intake port to take in air and an air discharge port to discharge the air. The display device includes a confluence portion configured to merge a first exhaust air discharged from the air discharge port and a second exhaust air discharged from an air conditioner for a cabin of the vehicle through an air outlet arranged in the cabin. The confluence portion is defined such that a first flow direction of the first exhaust air and a second flow direction of the second exhaust air coincide with each other.

Display device

A vehicular display apparatus is provided with an ambient-light luminous region that surrounds an outer periphery of a display region. An ambient light source emits light, which is then guided by an ambient-light guide body into an acrylic cylindrical body. The guided light is then outputted from a light output end face of the acrylic cylindrical body towards a light output direction. The light output end face forms the ambient-light luminous region. The vehicular display apparatus includes a light collection structure that collects an output light, which is outputted from the light output end face, towards the light output direction. Collecting the output light towards the light output direction enables the reduction of a light leakage to a direction different from the light output direction, improving an outputted luminance of the ambient-light luminous region.

Vehicular display apparatus

A display apparatus provides a display region to display information, and a peripheral light luminous region to output light. The display apparatus includes an indicator light source and a coloring transmissive member made of light transmissive material. The coloring transmissive member includes a light input face where the light emitted from the indicator light source enters; a light output face with a belt-like shape in an extended direction to form the light luminous region by outputting light inputted from the light input face; and an attenuation portion attenuating light transmitting from the light input face to the light output face. The attenuation portion has a thickness between the light input face and the light output face. The thickness changes to increase in the extended direction of the light output face as going from a central portion towards each of both end portions.
