There is provided a screen capable of preventing generation of a double image even in a lateral direction, and improving the image quality as a whole, and a head-up display device having incorporated therein. The combiner 20 of the head-up display device of the present invention has a main body layer 20a which functions as a screen and is sandwiched between a first concave optical surface 21 located at an observation side and a second convex optical surface 22 located at a side opposite to the observation side. The thickness of the main body layer 20a becomes thinner from the center toward the periphery with regard to a lateral direction D2, and variation of the thickness of the main body layer 20a with regard to a vertical direction D1 is different for the central part and the peripheral part with regard to the lateral direction D2.
