PROBLEM TO BE SOLVED: To provide a road surface display device which can achieve display having a high visibility.SOLUTION: A road surface display device (1) comprises light projection units (7, 107, 207, 307) which project light (24) towards a road surface and perform display on the road surface by the light, and a polarization control unit (11) which sets a ratio of P polarization and S polarization of the light. It is preferable that the road surface display device comprises a target position detection unit (13) which detects a position of a target, and the polarization control unit sets the ratio according to a position of the target.SELECTED DRAWING: Figure 1

    【課題】視認性が高い表示を行うことができる路面表示装置を提供すること。【解決手段】路面に向けて光(24)を投射し、前記路面上で前記光による表示を行う光投射ユニット(7、107、207、307)と、前記光におけるP偏光及びS偏光の比率を設定する偏光制御ユニット(11)と、を備えることを特徴とする路面表示装置(1)。路面表示装置は、物標の位置を検出する物標位置検出ユニット(13)を備え、前記偏光制御ユニットは、前記物標の位置に応じて前記比率を設定することが好ましい。【選択図】 図1
