Title: Thermal head
Inventor: HASEGAWA YASUSHI
IPC: B41J2/345
Filed: 1989-12-26
Abstract: PURPOSE:To prevent a chip from inclining to enhance reliability by a method wherein a driver IC is mounted by a face down bonding method, and a solder dam diameter of a substrate electrode part on an input side with the small number of connecting bumps is made smaller than that on an output side. CONSTITUTION:A driver IC 4 is mounted on a substrate 3 so that solder bumps 6, 6' of the driver IC 4 are positionally adjusted to electrodes 17, 17' on the insulating substrate 3. Thereafter, the solder bumps 6, 6' of the driver IC 4 are fused to conduct an electrical connection. At this time, a solder dam diameter B of an input-side electrode part with the small number of bumps is made smaller than a solder dam diameter A of an output-side electrode with the large number of bumps. In this manner, the height of the bump on the input side can be made thicker than that on the output side. As a result, because this difference in height is offset by the inclination of an IC chip to the input side under its own weight, the inclination-free bonding state of the IC chip is obtained.

Title: Liquid crystal display device
Inventor: KOJIMA HIDETSUGU
IPC: G09F9/35
Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display device that has a high numerical aperture and also has a uniform numerical aperture ratio between pixels in a display area. SOLUTION: An auxiliary capacity electrode 14 is formed over peripheral edges on three sides of a pixel electrode 19 on a TFT substrate side across an insulating film.
