Abstract

PURPOSE:To prevent irregularity of brightness by making scanning-side electrodes wider than signal electrodes, and decreasing the resistance of an electric circuit connected to a driving circuit. CONSTITUTION:A liquid-crystal display element consists of glass 1, electrode terminals 2 formed thereupon, zebra connectors 3, printed circuit board 4, electrode terminals 5 formed thereupon, signal-side electrode terminals 6, and scanning-side electrode terminals 7; and the electrode terminals 2 and 5 are connected mutually by the zebra connectors 3 and the scanning-side electrode terminals 7 are wider than the signal-side electrode terminals 6. Therefore, the scanning-side electric resistance is decreased, so a voltage drop due to voltage application is reduced to prevent the irregularity of brightness.

使用するなどの方法を用いている。In liquid crystal display elements, it is necessary to lower the electrical resistance as much as possible. 411 The scanning side electrode should be as low as possible for full dot matrix type liquid crystal display devices such as graphics, which have a large number of time divisions and a number of lines of 32 or more. , methods such as increasing the width of the terminals and using connectors with low connection resistance are used.

う欠点かあ−った。Conventionally, the signal side electrode terminal width and the scanning side electrode terminal width were equal, and the electrical resistance between them was the same on the signal side and the scanning side in connection with the drive circuit. Therefore, on the scanning side where the line distance is long, the electric resistance becomes large, which is disadvantageous.

本発明の目的は、走査側電極の電気的抵抗を増加させな

晶表示素子を提供することにある。An object of the present invention is to provide a liquid crystal display element that can reduce connection resistance with a drive circuit without increasing the electrical resistance of the scanning side electrode.

以下、本発明の一実施例を図により説明する。Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

3 is a zebra connector, 54 is a printed circuit board, 5 is an electrode terminal on the printed circuit board 4, 6 is a signal side electrode terminal, and 7 is a scanning side electrode terminal. Both electrode terminals 2.5 are connected by a zebra connector 3, and the scanning side electrode terminal 7 is made wider than the signal side electrode terminal 6.

When the width of the zebra connector 3 is increased, the number of conductive parts of the zebra connector 3 increases, and the resistance between them is small, about half that of the zebra connector 3. With respect to this width, the width of the scanning side electrode terminal 7 is 1.5 to 2

。According to the present invention, the electrical resistance on the scanning side can be kept small, so when an electrical signal is applied here, the potential drop can be made small. If the potential drop is large, display unevenness occurs, and a brightness unevenness phenomenon occurs in which contrast differs between areas near and far from the electrode portion. The present invention is effective in preventing such phenomena.
