An electrical part mounting apparatus includes a pressure measuring member for measuring the pressure of a pressure head, and a moving speed control member for controlling the moving speed of the pressure head. Accordingly, the electrical part mounting apparatus can freely change the pressure and the moving speed of the pressure head to desired values, and is suitable for connection between electrical parts.

Apparatus and method for mounting electrical parts

In a light-guide plate for use in a liquid crystal display device, light enters a transmissive plate member from one end face thereof, is reflected and diffused inside the plate member, and emerges from one main surface of the plate member. A guide member is formed integrally with the main surface so as to guide a light-diffusing sheet member to be placed thereon.

Liquid crystal display device having light-guide plate for reflecting and diffusing light-source light so that the light is uniformly incident on liquid crystal cell

Disclosed is a liquid crystal display device in which the effect of cutting off an electromagnetic wave generated from a liquid crystal module and a backlight portion in a shield member is improved and in which it is possible to ground the drive control circuit. A liquid crystal display device includes a shield member which is made of an elastic metal and which includes a casing portion having an opening and a plate portion substantially closing the opening, wherein the casing portion has in the entire periphery surrounding the opening a plurality of spring fingers protruding elastically outward, wherein a liquid crystal module and a backlight portion for illuminating the screen of the liquid crystal module are arranged inside the shield member, and wherein a substrate of a drive control circuit for driving and controlling the liquid crystal module and the backlight portion is arranged outside the shield member.

Disclosed is a flexible substrate whose conductor patterns can be firmly connected to conductor patterns of a printed circuit board. Conductor patterns for connection (4) are formed on one side of a flexible substrate so as to be opposed to conductor patterns (2) provided on a printed circuit board (1), wherein recesses (4b) or/and protrusions (4c) are provided on either side end of each conductor pattern for connection (4).

Flexible substrate

Disclosed herein is a liquid crystal display which can eliminate the nonuniformity of display contrast due to a difference in wiring resistance between electrode terminals of a liquid crystal panel. Two adjacent ones of the electrode terminals which are respectively connected to two adjacent ones of tape carriers are set substantially equal in length. Furthermore, two adjacent ones of the electrode terminals which are respectively connected to two of lead wires adjacent to each other with a lead pitch increased area interposed therebetween are set substantially equal in length.

A liquid crystal display in which an LCD is protected against the influence of static electricity or noise, and the color shading in the peripheral part of the display area of the LCD is suppressed. A ground terminal is provided in the area between the electrode terminals 5a and 5b of the LCD 1, the electrode terminals being adjacently positioned and connected to different flexible substrates 6 and 6. The ground terminal is electrically independent of the electrode terminal group 5's, and has a similar shape to that of the area between two electrode terminals. A ground pattern 13, which is independent of the lead pattern group 8's and connected to the ground terminal 12, is provided on each flexible substrate 6. The ground pattern 13 is grounded through a printed circuit board.
