1. A display apparatus comprising:
a display panel;
a lens configured to enable a user to see an image displayed on the display panel;
an image sensor for capturing an eye of the user looking at the display panel, the image sensor having a rectangular imaging plane; and
an imaging optical system for forming an optical image of the eye on the imaging plane, wherein
the imaging optical system has an optical axis that is nonparallel to an optical axis of the lens,
a projected line of the optical axis of the lens on the imaging plane is substantially parallel to a long side of the imaging plane,
the lens is a lens having a shape as obtained by removing a part of a peripheral portion of a circular shape from the circular shape in a view from the direction parallel to the optical axis of the lens, and
the imaging optical system is disposed such that at least part of the image sensor is included in a region as formed by removing the part of the peripheral portion in the view from the direction parallel to the optical axis of the lens.
