Beschreibung
Zusammenfassung:	The utility model provides an image generating unit which comprises a liquid crystal display screen, a light chamber, a backlight unit and a heat dissipation piece, the light chamber is arranged between the liquid crystal display screen and the backlight unit, heat dissipation glass is arranged on the outer side of the liquid crystal display screen, and the heat conductivity of the heat dissipation glass is larger than or equal to 1W/mK and smaller than or equal to 3W/mK when the temperature is 300K. The thickness of the heat dissipation glass is larger than or equal to 3 mm. The utility model also provides a head-up display device. According to the image generation unit and the head-up display device provided by the utility model, the thickness of the heat dissipation glass is increased, so that the heat dissipation glass can quickly absorb and store more heat generated by the liquid crystal display screen due to the fact that the liquid crystal display screen absorbs backward sunlight or backlight, and the
