         5 . The display device according to  claim 1 , wherein, in a cross-section orthogonal to a second axis, both ends of the second surface in the first axis direction are closer to the display panel than a center of the second surface in the first axis direction. 
     
     
         6 . The display device according to  claim 1 , wherein, when viewed from the second surface, both ends of the second surface in a second axis direction along a second axis are closer to an eye-point of a viewer than a center of the second surface in the second axis direction. 
     
     
         7 . A display device comprising:
 a cover member curved when viewed in a first axis direction along a first axis; and   a display panel disposed on one side of the cover member, wherein   the cover member has a first surface facing the display panel and a second surface on the opposite side of the first surface,   the first surface forms a straight line and at least a part of the second surface forms a curved line in a cross-section orthogonal to a second axis that is along a straight line extending from one end to the other end of the cover member when viewed in the first axis direction, and   the second surface forms a circular arc when viewed in the first axis direction.   
     
     
         8 . The display device according to  claim 7 , wherein a cross-sectional shape obtained by cutting the cover member along a plane orthogonal to the second axis is constant at any positions in a second axis direction along the second axis. 
     
     
         9 . The display device according to  claim 7 , wherein, in the cross-section orthogonal to the second axis, both ends of the second surface in the first axis direction are closer to the display panel than a center of the second surface in the first axis direction. 
     
     
         10 . The display device according to  claim 8 , wherein, when viewed in the cross-section orthogonal to the second axis, both ends of the second surface in the first axis direction are closer to the display panel than a center of the second surface in the first axis direction. 
     
     
         11 . The display device according to  claim 7 , wherein, when viewed from the second surface, both ends of the second surface in a second axis direction along the second axis are closer to an eye-point of an viewer than a center of the second surface in the second axis direction. 
     
     
         12 . The display device according to  claim 8 , wherein, when viewed from the second surface, both ends of the second surface in the second axis direction are closer to an eye-point of a viewer than a center of the second surface in the second axis direction. 
     
     
         13 . The display device according to  claim 9 , wherein, when viewed from the second surface, both ends of the second surface in a second axis direction along the second axis are closer to an eye-point of a viewer than a center of the second surface in the second axis direction. 
     
     
         14 . The display device according to  claim 10 , wherein, when viewed from the second surface, both ends of the second surface in the second axis direction are closer to an eye-point of a viewer than a center of the second surface in the second axis direction.
