Display device, electronic apparatus, and manufacturing method of display device
A display device for displaying an image on a display surface includes a liquid crystal panel having the display surface, the liquid crystal panel with a first through hole formed in the display surface, a backlight disposed oppositely to the liquid crystal panel, the backlight with a second through hole formed at a position overlapping with the first through hole, and a cap inserted into the first through hole and the second through hole. The cap includes a tube portion with a third through hole formed, the third through hole parallel to the first through hole and the second through hole, and a flange portion formed at least one end of the tube portion, the flange portion having an outer diameter larger than a diameter of the first through hole, and larger than a diameter of the second through hole.
1. A display device for displaying an image on a display surface, the display device comprising:
a liquid crystal panel having a first through hole provided in the display surface;
a backlight having a second through hole provided at a position overlapping with the first through hole; and
a cap inserted into the first through hole and the second through hole,
the cap including
a tube portion including a first end arranged at the liquid crystal panel side, and
a first flange portion provided on the first end,
wherein the first flange portion includes an outer diameter that is larger than a diameter of the first through hole,
wherein the liquid crystal panel further includes:
a first substrate having a first substrate hole,
a second substrate having a second substrate hole,
a liquid crystal provided between the first substrate and the second substrate, and
a first polarizer having a first polarizer hole,
wherein the first through hole passes through from the first substrate to the second substrate,
wherein a seal is provided between the first substrate and the second substrate so as to surround a periphery of the first through hole and be spaced from the first through hole, and has a seal hole,
wherein the first through hole includes the first polarizer hole, the first substrate hole, the seal hole, and the second substrate hole, and
wherein a diameter of the first substrate hole and a diameter of the second substrate hole are each smaller than a diameter of the seal hole.
2. The display device according to claim 1 , wherein
the outer diameter of the first flange portion is larger than the diameter of the seal hole, and
the first polarizer is sandwiched between the first flange portion and the first substrate.
3. The display device according to claim 1 , wherein
the cap includes a second flange portion provided on a second end arranged at the backlight side of the tube portion.
4. The display device according to claim 1 , wherein
the cap includes non-translucent resin.
5. An electronic apparatus comprising:
the display device according to claim 1 ;
a control unit configured to supply an input signal to the display device; and
a movement mechanism including
an indicator needle disposed along the display surface of the display device,
a rotational shaft inserted into a third through hole that is provided in the tube portion and that is parallel to the first through hole and the second through hole, and
a motor configured to rotate the rotational shaft, the motor being disposed on an opposite side of the display device to the display surface.
