  • the element mounting section 155 which is reinforced by the reinforcing plate 153 in the belt-like cable 150 is held by the holding portion 167. Therefore, as compared with the case where the cable section 158 whose rigidity is lower than that of the element mounting section 155 is held by the holding portion 167, the deformation for moving the element 154 is less likely to occur in the strip cable 150. Therefore, the collision of the element 154 is more suppressed.
  • the element mounting section 155 is held by the holding portion 167 in a posture extending along the surface of the illumination substrate 141. Therefore, the strip cable 150 is unlikely to be deformed as the element mounting section 155 moves in the pull-in direction. Therefore, the collision of the element 154 is further suppressed.
  • the holding portion 167 holds a position near the front end 156 in the element mounting section 155.
  • deformation in the cable section 158 extending from the front end 156 of the element mounting section 155 to the panel end 151 is suppressed as compared with the case where the holding section 167 holds a position close to the back end 157. Therefore, it is difficult to apply a force to the connection between the strip cable 150 and the display panel 120.
  • a position near the front end 156 in the element mounting section 155 is held by the holding portion 167.
  • the position near the rear end 157 in the element mounting section 155 is not held by the holding portion 167. Therefore, the protrusion of the casing 160 in the pull-out direction in the back direction more than the center of the element mounting section 155 is suppressed. Therefore, the casing 160 is disposed in the back direction more than the center of the element mounting section 155 and is less likely to contact the dial 101 forming the pointer display unit 10.
  • the pointer display unit 10 corresponds to the “first display unit”
  • the image display unit 20 corresponds to the “second display unit”.
  • the control substrate 106 corresponds to a “signal output unit”
  • the illumination substrate 141 corresponds to a “back member”
  • the substrate support unit 163 corresponds to a “support unit”.
  • the clamping part 167 in the modification 1 regarding the above-mentioned embodiment is formed in the band plate shape extended in the width direction from the level
  • the sandwiching portion 167 covers the lighting substrate 141 and the band-like cable 150 in the entire width direction. Further, the tip end of the holding portion 167 of the first modification is suppressed in movement in the pulling direction by being pushed in the pulling direction of the engaging portion 168.
  • the sandwiching portion 167 in the second modification covers a position near the rear end 157 in the element mounting section 155.
  • the sandwiching portion 167 in the third modification covers the cable section of the strip-like cable 150.
  • Each sandwiching portion 167 in the fourth modification is formed so as to have a positional relationship in which the other is shifted in the front direction or the back direction with respect to one. Also in the first to fourth modifications, the sandwiching portion 167 can sandwich the illumination substrate 141 and the band-like cable 150 with the substrate support portion 163.
  • the display apparatus 100 in the modification 5 regarding the above-mentioned embodiment does not have the illumination unit 140 using the display member in which the pixel which light-emits by itself organic EL etc. was formed as the display panel 120.
  • the casing 160 does not have the substrate support portion 163.
  • the pinching portion 167 pinches the band-like cable 150 with the support portion 166.
  • the collision of the element 154 with the dial plate 101 or the like is suppressed.
  • the support portion 166 corresponds to the “support portion”.
  • the band cable 150 in the modified example 6 regarding the above-mentioned embodiment does not have the element 154 mounted. Also in the sixth modification, the belt-like cable 150 is pinched by the pinching portion 167 and deformation is suppressed.
