A method has been used in which the scanning side electrodes 6.6 are divided into two groups, line-sequential scanning is performed within each n group, and the display is displayed on a scale twice the number of scanning lines actually scanned.

いた。Alternatively, as shown in Japanese Patent Publication No. 53-101993, the electrodes to be scanned simultaneously among the two groups of scanning side electrodes are connected with transparent electrodes on the liquid crystal sealing glass, and half the number of scanning lines is Problems to be Solved by the Invention In such a conventional method, two groups of scanning side electrode rows and the same number of terminal rows on a printed wiring board are connected using connectors. Wiring must be done on the printed wiring board so that a common scanning signal can be supplied to the electrode rows, and it is also necessary to arrange the same number of terminal rows as the number of scanning lines on the printed wiring board, so the printed wiring board is large. 1.Also, since the printed wiring board is approximately the same size as the liquid crystal sealing glass, the printed wiring board covers the entire liquid crystal sealing glass, and the structure of the printed wiring board is similar to that of the liquid crystal sealing glass. This made it difficult to illuminate the screen from behind, creating an extremely large obstacle in the production of transmissive liquid crystal display devices.

いた。In addition, the method of connecting the scanning side electrodes divided into two groups using transparent electrodes on the liquid crystal sealing glass requires a glass part for wiring in addition to the glass necessary for display, which increases the glass size. This was also a factor in high costs.
