The present invention provides a screen capable of suppressing the generation of double images even in the lateral direction and improving the image quality as a whole, and a head-up display device incorporating the same. A combiner (20) of a head-up display device according to the present invention serves as a screen and is provided with a main body layer (20a) sandwiched between a concave firstoptical surface (21) on an observation side and a convex second optical surface (22) on a reverse observation side. The thickness of the main body layer (20a) becomes thinner from the center to the periphery with respect to the lateral direction (D2), and the variation in the thickness of the main body layer (20a) with respect to the vertical direction (D1) is different between the central portionand the peripheral portion with respect to the lateral direction (D2). 本发明提供种即使在横向上也能够抑制双重图像的产生从而提高整体的画质的屏幕以及设置有该屏幕的平视显示装置。本发明的平视显示装置的组合器(20)具备主体层(20a)，该主体层(20a)作为屏幕发挥功能，被在观察侧为凹的第光学面(21)和在反观察侧为凸的第二光学面(22)夹持。主体层(20a)的厚度在横向(D2)
