A color filter 43 is formed in a portion where a pixel is formed on a transparent electrode 42 such as ITO (tin oxide-doped indium oxide) which is selectively formed on the segment substrate 51, as shown in FIG. A structure in which a transparent electrode 53 such as ITO is selectively formed after the color filter 52 is formed thereon is generally used.

【発明が解決しようとする課題】しかしながら、カラー

ネルを駆動する際、カラーフィルタのない液晶パネルを
駆動する場合よりも高い電圧が必要となる問題点を有し
ていた。However, since the color filter is not conductive, the voltage actually applied to the liquid crystal is lower than the voltage applied to the transparent electrode in the former case due to the electric capacity due to its film thickness. Therefore, there is a problem that a higher voltage is required when driving the liquid crystal panel than when driving a liquid crystal panel without a color filter.

ＩＴＯが形成され、上記と同様に液晶パネルを駆動する
際、高い電圧が必要となるという問題点を有していた。In the latter case, since the transparent electrode 53 is on the color filter 52, the above-mentioned problem does not occur, but the color filter is destroyed at a high temperature (about 200 ° C. or higher). When a transparent electrode such as ITO is formed on the upper surface, it must be formed at a temperature lower than 200 ° C. However, since ITO has a lower resistance as it is formed at a higher temperature, ITO having a high resistance value is formed in this case, and a high voltage is required when driving the liquid crystal panel as in the above case. Was.
