To provide a head-up display device excellent in visibility when viewed through polarizing sunglasses, as well as excellent in thermostability.SOLUTION: A head-up display device includes: a display including a display cell and a polarizing plate with a first retardation layer having a polarizer and a first retardation layer sequentially from the display cell side on an emission side of the display cell, the display configured to emit projection light; at least one reflector configured to reflect projection light; and a polarizing plate with a second retardation layer disposed on an opposite side of the reflector and having a polarizer and a second retardation layer sequentially from the reflector side. An in-plane retardation Re(550) of each of the first retardation layer and the second retardation layer is 100 nm-200 nm.SELECTED DRAWING: Figure 1
