the liquid crystal panel includes a third region surrounding the first region outside the camera,
the controller controls the liquid crystal panel to display an annular first pattern in the third region corresponding to the first opening mode and to display an annular second pattern in the third region corresponding to the second opening mode, and
area of an opening pattern displayed inside the second pattern is smaller than area of an opening pattern displayed inside the first pattern.
4. The electronic apparatus of claim 3 , further comprising:
a light guide having a side surface and a main surface opposed to the liquid crystal panel; and
a light source opposed to the side surface,
wherein
the third region is overlaid on the light guide.
5. The electronic apparatus of claim 4 , wherein
the light guide includes a first through hole, and
the first region and the second region are overlaid on the first through hole.
6. The electronic apparatus of claim 5 , wherein
the camera is provided in the first through hole.
7. The electronic apparatus of claim 6 , further comprising:
an optical sheet located between the light guide and the liquid crystal panel,
wherein
the optical sheet includes a second through hole overlaid on the first through hole.
8. The electronic apparatus of claim 7 , further comprising:
a reflective sheet,
wherein
the light guide is located between the reflective sheet and the optical sheet, and
the reflective sheet includes a third through hole overlaid on the first through hole.
9. The electronic apparatus of claim 5 , further comprising:
an optical sheet located between the light guide and the liquid crystal panel,
wherein
the optical sheet includes a second through hole overlaid on the first through hole.
10. The electronic apparatus of claim 9 , further comprising:
a reflective sheet,
wherein
the light guide is located between the reflective sheet and the optical sheet, and
the reflective sheet includes a third through hole overlaid on the first through hole.
11. The electronic apparatus of claim 1 , wherein
the liquid crystal panel includes a third region surrounding the first region outside the camera,
the controller controls the liquid crystal panel to display an annular first pattern in the third region corresponding to the first opening mode and to display an annular second pattern in the third region corresponding to the second opening mode, and
area of an opening pattern displayed inside the second pattern is smaller than area of an opening pattern displayed inside the first pattern.
12. The electronic apparatus of claim 11 , further comprising:
a light guide having a side surface and a main surface opposed to the liquid crystal panel; and
a light source opposed to the side surface,
wherein
the third region is overlaid on the light guide.
13. The electronic apparatus of claim 12 , wherein
the light guide includes a first through hole, and
the first region and the second region are overlaid on the first through hole.
14. The electronic apparatus of claim 13 , wherein
the camera is provided in the first through hole.
15. A display device arranged in front of a camera, comprising:
a first polarizer;
a second polarizer; and
a liquid crystal panel located between the first polarizer and the second polarizer,
the liquid crystal panel including a first region and a second region which are overlaid on the camera, transmitting light through the first region and the second region in a first opening mode, and making a quantity of the light transmitted through in the first region smaller than a quantity of the light transmitted through the second region in a second opening mode.
16. The display device of claim 15 , wherein
the liquid crystal panel includes a third region surrounding the first region outside the camera, displays an annular first pattern in the third region in the first opening mode, and displays an annular second pattern in the third region in the second opening mode, and
