Liquid crystal display device

Abstract

PROBLEM TO BE SOLVED: To prevent malfunction and breakage of an LSI for liquid crystal driving due to static electricity by spreadingly providing a net shaped conductive pattern at the peripheral outside part of electrode wirings for liquid crystal driving provided on a liquid crystal display panel so as to enclose the wirings. SOLUTION: Electrode wirings for liquid crystal driving 15 and LSI input wirings 16 are spreadingly provided on a liquid crystal display panel 11 and a net shaped conductive pattern 14 is also speadingly provided at the perripheral outside part of the wirings 15, 16 and an LSI for liquid crystal driving 12 is mounted on the wirings 15 and the wirings 16. Since positive charge discharged on a crystal display surface by charged matters from the outside is grounded from the net shaped conductivre pattern 14 to the frame ground of a circuit substrate via the wirings 17 of a film connector 13 to be discharged, a magnetic field to be generated by a discharge current is made to be a minute magnetic field because a conductor is a net shape. Thus, effects due to an electromagnetic induction to the LSI for liquid crystal driving 12, the electrode wirings for liquid crystal driving 15 and the LSI input wirings 16 are reduced and the malfunction of the LSI for liquid crystal driving 12 is prevented.
