  "textContent": "A head-up display apparatus (1) is a head-up display apparatus capable of projecting a rectangular virtual image onto a virtual-image display unit disposed in front of a user in such a manner that a height of a left side of the rectangular virtual image as viewed from the user coincides with a height of a right side thereof. The head-up display apparatus (1) includes a display-light emitting unit (10) having a second inclination angle around the axis parallel to the vertical direction so that the first direction side thereof is closer to the user than the second direction side thereof is, and being configured to emit display light forming a rectangular image corresponding to the rectangular virtual image. The head-up display apparatus (1) includes a reflecting mirror (20) having a third inclination angle around the axis parallel to the vertical direction so that the first direction side thereof is closer to the user than the second direction side thereof is, and being configured to reflect the display light and emit reflected light to the virtual-image display unit.",
