Zusammenfassung:	Provided is a head-up display apparatus capable of preventing damage due to sunlight and ensuring user convenience. A reflection mirror M1 reflects an image created by a display panel 64 and projects it onto a display region. A solar radiation sensor 66 detects a sunlight intensity when a position of sun 60 exists within a predetermined detection range. A blocking mechanism 67 forms a projected light path of an image between the display region and the display panel 64 when being turned off, and blocks the projected light path of the image and an incident light path of the sunlight which is direction opposite thereto when being turned on. A protection processor controls ON / OFF of the blocking mechanism 67 based on an estimated temperature of the display panel 64, which is estimated by using a sunlight intensity from the solar radiation sensor 66, luminance of a light source 65, and an ambient temperature.
