Head-mounted display device with foveated pixels

A head-mounted display device comprising:

• an image display element displaying a two-dimensional image;
• a first eyepiece and a second eyepiece, each magnifying and projecting the image displayed by the image display element;
• and
• a holder holding the image display element, the first eyepiece, and the second eyepiece to a viewer's head, wherein
• the image display element is composed of:
• a first central portion having a flat display surface visible via a central portion of the first eyepiece and a second central portion having a flat display surface visible via a central portion of the second eyepiece, the first central portion and the second central portion being aligned along a common plane;
• and
• a first peripheral portion disposed around a periphery of the first central portion and a second peripheral portion disposed around the second central portion, the first peripheral portion being curved toward the first eyepiece away from the plane and the second peripheral portion being curved toward the second eyepiece away from the plane.

A head-mounted display device comprising:

• an image display element displaying a two-dimensional image;
• an eyepiece located in front of a screen of the image display element and forming a virtual image by magnifying the image displayed by the image display element;
• and
• a holder holding the image display element and the eyepiece to a viewer's head,
• wherein the image display element has a plurality of scan lines and a plurality of data lines intersecting with each other to form a matrix, and one pixel is located at each point of intersection,
• pixels in a peripheral portion of the screen are greater in size than pixels in a central portion of the screen,
• intervals between the scan lines and intervals between the data lines are greater in the peripheral portion of the screen than in the central portion of the screen, and
• width of the scan lines and width of the data lines increase as the intervals between the scan lines and the intervals between the data lines increase.
