Summary:PROBLEM TO BE SOLVED: To enhance product reliability and to consequently improve the yield of the product by thermally press-contacting an outgoing terminal and an inputting terminal for electrical connection, while the upper face of an anisotropic electrically conductive adhesive is pressurized with a pressing glass plate, which has the same thermal expansion coefficient as that of a glass substrate. SOLUTION: The outgoing terminal 3 from a driving circuit substrate 2 for driving a liquid crystal display device 1 is electrically connected to the inputting terminal 6 on the lower glass substrate 5 of the display device 1 by means of an anisotropic electrically conductive adhesive 4. While the upper face of the adhesive 4 is pressurized with a pressing glass plate having the same thermal expansion coefficient as that of the lower glass substrate 5, the outgoing terminal 3 and the inputting terminal 6 are thermally press-contacted. Thus, by homogenizing the materials between the pressing glass plate and the lower glass substrate 5, the thermal expansion coefficient of the two are equalized in a heated state. Consequently, the inter-electrode pitch of the inputting terminal 6 and that of the outgoing terminal 3 expand in the ratio at the same coefficient, thereby making no difference between their inter-electrode pitches.
