る。 FIG. 3 is a sectional view showing another embodiment of the present invention. This example is slightly different from the example shown in FIG. 2, in that the lower electrode substrate 8 has a periphery bent almost vertically downward like the upper electrode substrate 2 to form a vertical frame 8a, and a fixed frame 8a surrounding the outside of the vertical frame 8a. The structure is such that a liquid crystal layer 5 filled with liquid crystal is formed through an insulating adhesive layer 4 having a thickness of 100 mm, and is fitted into the vertical frame 2a of the upper electrode substrate 2. Therefore, the polarizing plate 1a is coated on the surface of the lower electrode substrate 8 opposite to the liquid crystal layer 5, and the reflecting plate 9 is further coated on the polarizing plate 1a.
As shown in the figure, the lower electrode substrate 2 is configured to fit within the vertical frame 8a, and in this example as well, the lower electrode substrate 2 is placed within the vertical frame 2a formed by bending the periphery of the upper electrode substrate 2 in the downward vertical direction. 8 is fitted, and the conductive rubber 7 is also disposed at the lowest position within the vertical frame 2a.As with the example shown in FIG. This allows display symbols, numbers, etc. to be displayed in a larger size, and if the display area is kept the same as before, the external size can be reduced and the device can be made smaller and lighter.

う利点もある。[Effects of the invention] As described above, the present invention, in a liquid crystal display panel of a liquid crystal display device, has both the upper and lower electrode substrates made of plastic plates, and the periphery of the upper electrode substrate is bent vertically downward to form a vertical frame. A lower electrode substrate is fitted onto the lower electrode substrate, and a conductive member is disposed below the lower end surface of the upper electrode substrate for connecting the transparent electrode of the upper electrode substrate to the electric circuit for driving the device. Therefore, if the external shape of the device is kept the same as before, the display area can be increased by expanding the area of the lower electrode substrate that faces the upper electrode substrate through the liquid crystal material, and the size of display symbols, numbers, etc. can be increased. On the other hand, if the display area is kept the same as before, the external size of the device can be reduced to make it smaller and lighter. Another advantage is that there is no risk of breakage compared to those using glass plates as electrode substrates.
