るという欠点をも有していた。<Prior Art> Conventionally, a general structure of a liquid crystal display unit which is formed by integrating a liquid crystal display element and a drive circuit board for the liquid crystal display element is as shown in FIG. That is, liquid crystal is sealed between two glass substrates,
A liquid crystal cell 1 with polarizing plates pasted on its upper and lower surfaces and a drive circuit board 2 on which a drive circuit for the liquid crystal cell 1 is mounted are electrically connected by a conductive rubber connector 3, and a metal angle 4, the liquid crystal cell 1 was fixed to the drive circuit board 2 and assembled. However, in the above-mentioned conventional liquid crystal display unit, especially in the case of a high-density display element using a large liquid crystal cell, misalignment between the electrode terminal of the liquid crystal cell 1 and the drive circuit board 2 is likely to occur. Therefore, it took a lot of effort to align and assemble. In particular, when connecting one end of the drive circuit board 2 to one electrode terminal of the liquid crystal cell 1, the connection can be made on the same plane. When connecting and integrating the remaining electrode terminals of the cell 1, it is required to connect and fix the drive circuit board 2 and the liquid crystal cell 1 after forming them in a laminated state, resulting in extremely poor workability. Another drawback is that leakage occurs at the interface between the electrode terminals of the liquid crystal cell 1 and the conductive rubber connector 3 due to moisture.

Reference numeral 5 denotes a liquid crystal cell in which liquid crystal is sealed between two glass substrates, and polarizing plates are attached to the upper and lower surfaces of the liquid crystal cell, and electrode terminals are provided at the ends of the segment side substrates of the liquid crystal cell 5. and the drive circuit board 6 are connected by heat sealing using a flexible printed circuit board 7 (such as an anisotropic conductive film manufactured by Sony Chemical). When the flexible printed circuit board 7 is bent, a chassis 8 made of plastic resin is held between the liquid crystal cell 5 and the drive circuit board 6. A plan view of the chassis 8 is shown in FIG. 2b, and a side view is shown in FIG. 2c. Protrusions 8a are provided at the four corners of the chassis 8 to align the drive circuit board 6 and prevent it from wobbling. Further, in the center of the chassis 8, there is a T-shaped protrusion 8 that engages with the drive circuit board 6.
b is provided. A taper is formed on the side of the T-shaped projection 8b to facilitate insertion of the drive circuit board 6.

FIG. 2 shows a perspective view of the display unit as seen from the oblique rear surface thereof. In the figure, 9 is a fixed angle, and a claw 9a is formed on the periphery of the fixed angle 9. The claw 9a of this fixed angle 9 is attached to two driving circuit boards 6,
