Abstract
A HUD includes a plate that connects an emission-surface of the LCD and a heat sink, is formed of a material having a higher thermal conductivity than air, and is provided with an emission-surface exhaust heat path that is formed to: include a holding region fixed to a periphery of the emission-surface directly or via a material having a higher thermal conductivity than air, and an intermediate region connecting the holding region and the heat sink; connect an end portion, which is opposite to the holding region, of the intermediate region with the heat sink directly or via a material having a higher thermal conductivity than air; extend from the emission-surface to the heat sink via the plate; and have a thermal gradient greater than that of a heat transfer path for transferring heat from the emission-surface to the heat sink by using air as a medium.
