PROBLEM TO BE SOLVED: To provide a head-up display device and a liquid crystal display device capable of ensuring visibility of a display image while suppressing power consumption.SOLUTION: The head-up display device includes a liquid crystal display device having a liquid crystal panel 1a that is illuminated with illumination light from a light source. The liquid crystal panel 1a includes a display side polarizing plate 22 and a reflective polarizing plate 21 opposing to each other to interpose a liquid crystal cell 10, and a light-shielding part 30, in which a segment forming region T is switched into one of a transmissive state and a non-transmissive state responding to an applied voltage. The light-shielding part 30 is formed to overlap an outer edge of the segment forming region T in a normal direction of the substrate, and is recognized as an edge enclosing the segment in a display image. When the segment forming region T is in a transmissive state, the segment is lit by illumination light while the segment forming region T and the background region B in a non-transmissive state are displayed in a reflection mode by the reflection of external light on the reflective polarizing plate 21.SELECTED DRAWING: Figure 3

    【課題】消費電力を抑えつつ表示像の視認性を確保できるヘッドアップディスプレイ装置及び液晶表示装置を提供する。【解決手段】ヘッドアップディスプレイ装置は、光源からの照明光に照明される液晶パネル1aを有する液晶表示装置を備える。液晶パネル1aは、液晶セル10を挟んで対向する表示側偏光板22及び反射型偏光板21と、遮光部30と、を備え、印加電圧に応じて、セグメント形成領域Tが透過状態と不透過状態とのいずれかに切り替えられる。遮光部30は、基板法線方向においてセグメント形成領域Tの外縁と重なるように形成され、表示像においてはセグメントを囲む縁部として視認される。セグメント形成領域Tが透過状態である場合にセグメントが照明光により点灯し、不透過状態のセグメント形成領域Tと背景領域Bとは、外光が反射型偏光板21で反射することにより反射表示される。【選択図】図3
