Abstract: A technique permitting the reduction in size of a semiconductor device is provided. In a BGA type semiconductor device with a semiconductor chip flip-chip-bonded onto a wiring substrate, bump electrodes of the semiconductor chip are coupled to lands formed at an upper surface of the wiring substrate. The lands at the upper surface of the wiring substrate are coupled electrically to solder balls formed on a lower surface of the wiring substrate. Therefore, the lands include first type lands with lead-out lines coupled thereto and second type lands with lead-out lines not coupled thereto but with vias formed just thereunder. The lands are arrayed in six or more rows at equal pitches in an advancing direction of the rows. However, a row-to-row pitch is not made an equal pitch. In land rows which are likely to cause a short-circuit, the pitch between adjacent rows is made large, while in land rows which are difficult to cause a short-circuit, the pitch between adjacent rows is made small.

Abstract: An optical position of a display device with respect to an optical axis of a projection optical system is displaced in a direction perpendicular to the optical axis in accordance with a change in the size of a projected image. For instance, a transparent flat plate is disposed in front of a projection lens, and the transparent flat plate is tilted in association with a rotation of a zoom adjustment ring. As the transparent flat plate is tilted, the apparent position of the display device relative to the projection lens is displaced in the direction perpendicular to the optical axis of the projection optical system. Thereby, the projected image on a screen is located at a proper position corresponding to a zoom state. Tilt control of the transparent flat plate is realized by a cam mechanism, for instance.
