A liquid crystal display device includes first and second electrodes and an insulating film. The first electrode is formed on a substrate as one of two electrodes of an accumulation capacitor and applied with a voltage. The insulating film is formed on the first electrode to cover the first electrode. The second electrode is formed on the first electrode via the insulating film as the other electrode of the accumulation capacitor and including a first conductive film and a second conductive film formed on the first conductive film.

Liquid crystal display device with less pixel error and method of manufacturing the same

A liquid crystal display panel is improved in production yield, production efficiency and in display quality due to its easiness of checking alignment of a polarizer with respect to its corresponding TFT substrate. The liquid crystal display panel is easily downsized. In the liquid crystal display panel, the TFT substrate is provided with alignment checking marks for checking alignment of the polarizer with respect to the TFT substrate. Each of these marks are formed by selectively removing a part of each of common electrode wiring layers, and disposed under a light shielding layer formed on a color filter substrate, which presents a sharp contrast between the light shielding layer and these wiring layers to enhance a visual checking operation of alignment of the polarizer. The light shielding layer prevents light leakage in these alignment checking marks.

Liquid crystal display panel with plurality of alignment marks within the wiring layer

A liquid-crystal display panel has a pair of transparent substrates for sandwiching liquid crystal. The outer periphery of the substrates are bonded together with an adhesive except for a liquid-crystal inlet. Electrodes disposed on both the substrates are electrically connected by a transfer electrode disposed at the liquid-crystal inlet. The transfer electrode includes first and second electrode sections disposed on first and second substrates, respectively, and a conductive paste for electrically connecting the first and second electrode sections together and for sealing the liquid crystal at the inlet.
