To provide a drawing system capable of suppressing luminance unevenness in a video displayed using a laser beam.SOLUTION: A drawing system according to an embodiment comprises: a light output section that outputs a drawing laser beam including a laser beam of at least one color of red, green, and blue: a scanning section that scans the drawing laser beam output from the light output section so as to draw a video; and a video display section that displays the video drawn by the drawing laser beam scanned in the scanning section. The drawing laser beam is predetermined linear polarized light with respect to the video display section. The video display section includes a transparent display mechanism in which a plurality of optical elements having a convex curved shape at the light output section side are regularly arranged, and a reflection type polarizing element selectively reflecting the predetermined linear polarized light, and the reflection type polarizing element is positioned on a side opposite to the light output section with respect to the display mechanism.SELECTED DRAWING: Figure 4 【課題】レーザ光を用いて表示される映像において輝度ムラを抑制可能な描画システムを提供する。【解決手段】一実施形態に係る描画システムは、赤色、緑色および青色のうちの少なくとも１色のレーザ光を含む描画レーザ光を出力する光出力部と、光出力部から出力された描画レーザ光を、映像を描画するように走査する走査部と、走査部で走査された描画レーザ光によって描画される映像を表示する映像表示部とを備え、描画レーザ光は、映像表示部に対して所定の直線偏光光であり、映像表示部は、光出力部側に凸な湾曲形状を有する複数の光学素子が規則的に配列されおり透明な表示機構と、所定の直線偏光光を選択的に反射する反射型偏光素子とを有し、反射型偏光素子は、表示機構に対して光出力部と反対側に位置する。【選択図】図４
