In a solid-state imaging device, a pixel has a first island-shaped semiconductor (P11) formed on a substrate (1) and a drive output circuit has second island-shaped semiconductors (4a to 4c) formed on the substrate at the same height as that of the first island-shaped semiconductor (P11). The first island-shaped semiconductor (P11) has a first gate insulating layer (6b) formed on an outer periphery thereof and a first gate conductor layer (105a) surrounding the first gate insulating layer (6b). The second island-shaped semiconductors (4a to 4c) have a second gate insulating layer (6a) formed on an outer periphery thereof and a second gate conductor layer (7a) surrounding the second gate insulating layer (6a). The first gate conductor layer (105a) and the second gate conductor layer (7a) have bottom portions located on the same plane.

An optical disc apparatus has the following arrangements. Specifically, the optical disc apparatus includes a lock pin and a lock arm. The lock pin is disposed on a side of an inner surface of a case of the apparatus, being tapered in a protruding direction thereof. The lock arm is disposed on a side of a tray of the apparatus. The lock arm, urged by a resilient member, includes a hook portion to be engaged with an inclined surface of the lock pin. When the tray has moved to a predetermined position within the case, the lock arm is engaged with the lock pin, so that the tray is held in position at the predetermined position. When an impact force equal to, or more than, a predetermined value is applied to the optical disc apparatus, the hook portion of the lock arm is displaced in the protruding direction of the lock pin along the inclined surface of the lock pin, thereby disengaged from the lock pin. Engagement of the tray is thereby released.

A front surface of the opposite electrode of a liquid crystal display panel is formed in a curved shape. The relation between the reflecting surface of the pixel electrode and the curved surface of the opposite substrate is defined so that a leaving direction of the light that is reflected by the first face of the opposite substrate is different from a leaving direction of light that is emitted from the first face of the opposite substrate after having been reflected by the pixel electrodes through the liquid crystal layer. Thus, undesired light on the front surface of the opposite substrate is separated from light that is displayed. Consequently, an image free of dazzling and deterioration of contrast ratio due to undesired reflected light can be obtained with a high contrast ratio. In a display apparatus containing the reflection type liquid crystal display, an incident surface to a dichroic prism is an inclined surface including a curved surface, not a surface that is perpendicular to the optical axis. Thus, signal light that is reflected on each reflection type liquid crystal display panel and that is displayed can be separated from undesired light that is reflected on the surface of the dichroic prism. Thus, an image with a high quality, and a high contrast ratio can be displayed.

A display device comprises a display panel, a scanning circuit section for supplying a scanning signal to scanning lines of the display panel, and a scanning control circuit section for supplying an n-bit (n: 2 or more positive integer) input numeral signal and an inverted replica of the input numeral signal to the scanning circuit section. In the display device, a scanning circuit section comprises an input connection line group having sets of input connection lines for receiving bits of the input numeral signal and bits of the inverted replica of the input numeral signal, a plurality of logic circuit sections, less in number than the scanning lines, for responding to combinations of the input numeral signal and its inverted replica, and an output distributing unit for assigning an output from one logic circuit section to at least two scanning lines. It is, therefore, possible to suppress an increase in the number of connection lines and of the logic circuit sections involving a high definition of a display device and hence to manufacture a display device in a high yield.

A color image sensing system includes a CCD image sensor with an optical color filter. A CCD driver is provided to electrically drive the image sensor, which is attached to a vibration table serving as a swing-driver for moving the image sensor along a horizontal direction such that each cell of the image sensor shifts, in a frame period including first and second field periods, between four different sampling positions substantially aligned in the horizontal direction. During each field period, each cell is positioned at two sampling positions, wherein a brightness signal component is produced at one sampling position and color signal components are produced at these sampling positions. The distance between two sampling positions at which the brightness signal components of the first and second field images are produced is set to be half the horizontal pitch of the cells of the image sensor. The remaining two sampling positions of the four sampling positions are apart from each other by one-and-half times the horizontal cell pitch. A color frame image is thus reproduced by electrically adding the first and second field images to increase the number of picture elements to more than the actual number of cells, thereby improving the horizontal image resolution of the frame image and minimizing the generation of color moire in the frame image. The swing-drive operation of the image sensor is repeated in synchronism with the frame period.
