Disclosed is a head-up display device for vehicles. The display device for vehicles includes a panel, on which driving data of a vehicle are displayed; and an aspheric combiner, which magnifies the driving data displayed on the panel and thus creates a virtual image, and has a ratio of DISC to CRC satisfying the below expression (here, 0&#x3c;|DISC/CRC|&#x3c;1.0, DISC representing the distance on an optical route between the panel and the combiner, and CRC representing the radius of curvature of the combiner).

A polarization conversion system comprises a glass substrate; reflection type polarization plates, formed between top and bottom surfaces of the glass substrate and inclined at a predetermined angle, separating unpolarized incident light into two polarization directions where two directions are at a right angle to each other; polarization conversion plates coupled to the reflection type polarization plates, converting a polarization direction of polarization light by the reflection type polarization plates; and reflection plates positioned in parallel with the reflection type polarization plates, reflecting incident light from the reflection type polarization plates.
