To provide a vehicle information display device which can display high resolution image information, and to provide a vehicle information display system which uses the vehicle information display device so as to be able to display information inside and outside a vehicle.SOLUTION: A vehicle information display device which displays information inside a vehicle using a part of a windshield of the vehicle as a display region comprises: an image display unit which is installed inside the vehicle and projects image light carrying the information; a transparent sheet which is installed at an inner side of the display region set on a part of the windshield; and a light direction conversion panel which converts a direction of the image light from the image display unit toward the transparent sheet. The transparent sheet is configured to: include a phase difference plate, an absorption type polarization plate which absorbs specific polarized waves, and a transparent sheet material having light diffusion action arranged in this order from the windshield to the image display unit; and display the information carried by the image light having the direction converted by the light direction conversion panel to the inside of the vehicle.SELECTED DRAWING: Figure 3

    【課題】高解像度な映像情報を表示可能な車両情報表示装置とそれを利用して車両の内・外に情報を表示可能な車両用情報表示システムを提供する。【解決手段】車両のシールドガラスの一部を表示領域として利用し、情報を前記車両の内部に表示する車両情報表示装置は、前記車両の内部に設けられ、前記情報の映像光を投射する映像表示装置と、前記シールドガラスの一部に設定された前記表示領域の内側面に設けられた透明シートと、前記映像表示装置からの前記映像光の方向を前記透明シートに向けて変換する光方向変換パネルと、前記透明シートは、前記シールドガラス側から前記映像表示装置に向かって順に、位相差板、特定の偏波を吸収する吸収型偏光板、光拡散作用を有した透明シート材を含み、前記光方向変換パネルによって、方向が変換された前記映像光による前記情報を、前記車両の内部に向けて表示する。【選択図】図3
