[Detailed Description of the Invention] The present invention! This invention relates to a nine-person screen O1l crystal panel in which the lead wires of a liquid crystal panel to which Trix is applied are integrated with a lower electrode support and taken out separately from the back surface thereof, and a method for manufacturing the same.

Conventionally, a plate-shaped substrate on which a large number of linear element electrodes are formed in parallel on its surface is arranged facing each other, especially when the electrodes cross at right angles, to form an upper electrode and a lower electrode, respectively.Furthermore, a nematic liquid crystal, for example, is placed between the lower electrodes. A liquid crystal display panel is used in which a liquid crystal display panel is encapsulated and a matrix voltage is applied to the element electrodes.

The driving of a conventional liquid crystal display panel of this quality will be explained by taking a character display having a 5.times.7 dot structure as an example, with reference to the plan view of the O panel in FIG.
