Abstract

PURPOSE:To make a liquid crystal display element compact by arranging a liquid crystal display element driving IC on a seal material area for fixing a pair of bases. CONSTITUTION:The liquid crystal display element driving IC 3 is arranged on the seal material forming area of a seal material 4 for fixing the bases 1, 2 holding a liquid crystal layer between them. The seal material 4 acts as also a bonding material. Since a wiring between the IC 3 and an electrode in the liquid crystal display element is shortened, the reliability of the element can be improved and the element can be made compact.

５８６号公報）。Conventionally, as shown in FIGS. 2 and 3, for the purpose of making the liquid crystal display device more compact and highly reliable, a substrate 1 is used, in which an IC 3 for driving a liquid crystal display element is fixedly sandwiched between sealing materials 4. , 2, and electrical connection between the voltage application terminal of the liquid crystal display element and the IC is proposed by wire bonding (Utility Model Application Publication No. 54-82).
Publication No. 586).

It is necessary to provide wiring terminals in three directions.

By providing a space for mounting the chip and guarding it with a packaging sealant for the liquid crystal display element, the reliability of the LSI chip can be increased and a compact design is possible.

ている。In conventional chip-on LCDs, chips are mounted on terminals in three directions in the case of chip-on high time division LCDs (Figure 2), and general-purpose liquid crystal display elements are mounted on terminals in one direction. (FIG. 3), the LSI is protected by bonding it with a bonding material 5 made of resin, for example.

本発明は、その一実施例を第１図に示す如く。An embodiment of the present invention is shown in FIG.

材５の役目をも兼ねている。A liquid crystal display element driving IC 3 is disposed in a region where a sealing material 4 made of, for example, epoxy material is formed to fix the substrates 1 and 2 sandwiching the liquid crystal layer therebetween. That is, in the present invention, the sealing material 4 also serves as the bonding material 5 in FIG. 1-2.

ＩＣ３と液晶表示素子の電極との間の配線が短縮化され

の接続が可能である。Reliability is improved because the wiring between the IC3 and the electrodes of the liquid crystal display element is shortened, and since the LSI chip is placed inside, wiring can be done on the upper and lower glass substrates separately, making it possible to connect terminals in multiple directions on the substrate. It is possible to connect from the other direction only in one direction without sending out the data.
