Display device, electronic apparatus, and manufacturing method of display device

A method for manufacturing a display device with a through hole provided in a display surface on which an image is displayed, the method comprising:

• aligning a liquid crystal panel having a first through hole and a backlight having a second through hole so that the first through hole and the second through hole overlap with each other;
• and
• inserting a cap 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 second end arranged at the backlight side, the tube portion includes a third through hole, and the third through hole is parallel to the first through hole and the second through hole, and
• a first flange portion provided on the first end,
• wherein the first flange portion includes an outer diameter that is larger than the first through hole,
• wherein the first flange portion contacts a top surface of the liquid crystal panel at a periphery of the first through hole and closes an area that the first through hole faces the tube portion,
• wherein the liquid crystal panel further has:
• a first substrate,
• a second substrate,
• a liquid crystal provided between the first substrate and the second substrate, and
• a through hole seal that is provided around the first through hole in a first direction, which is a direction of the display surface, between the first substrate and the second substrate in a second direction vertical to the first direction, so as to seal the liquid crystal,
• wherein the first through hole passes through the through hole seal in the second direction from the first substrate to the second substrate, and
• wherein the outer diameter of the first flange portion is larger than an inner diameter of the through hole seal and is equal to or smaller than an outer diameter of the through hole seal.

A display device for displaying an image on a display surface, the display device comprising:

• a liquid crystal panel having the display surface, the liquid crystal panel with a
• first through hole provided in the display surface;
• a backlight disposed oppositely to the liquid crystal panel, the backlight with 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 second end arranged at the backlight side, the tube portion includes a third through hole, and the third through hole is parallel to the first through hole and the second through hole, and
• a second flange portion provided on the second end,
• wherein the second flange portion includes an outer diameter that is larger than the second through hole,
• wherein the second flange portion contacts a top surface of the backlight at a periphery of the second through hole and closes an area that the second through hole faces the tube portion,
• wherein the liquid crystal panel further has:
• a first substrate,
• a second substrate,
• a liquid crystal provided between the first substrate and the second substrate, and
• a through hole seal that is provided around the first through hole in a first direction, which is a direction of the display surface, between the first substrate and the second substrate in a second direction vertical to the first direction, so as to seal the liquid crystal,
• wherein the first through hole passes through the through hole seal in the second direction from the first substrate to the second substrate, and
• wherein the outer diameter of the second flange portion is larger than an inner
• diameter of the through hole seal and is equal to or smaller than an outer diameter of the through hole seal.
