Abstract
A liquid crystal display having satisfactory visibility in a wide viewing angle range is provided. A TFT array substrate of the liquid crystal display includes scanning electrodes and signal electrodes arranged in a matrix shape, thin-film transistors respectively disposed at intersections between the scanning electrodes and the signal electrodes, first pixel electrodes respectively connected to the signal electrodes via the thin-film transistors, connecting capacitor electrodes formed in a layer including gate electrodes of the thin-film transistors, and second pixel electrodes capacitively connected to the first pixel electrodes via the connecting capacitor electrodes. It is not necessary to use any additional process to form the second electrodes, leading to advantages that the product yield is improved and production cost is lowered. Each pixel is divided into plural areas having different directions of orientation and into plural areas being applied with different voltages. Due to existence of the areas having different directions of orientation, there is attained a vertically symmetric transmittivity characteristic. Moreover, adjusting the surface ratio and the application voltage ratio between the areas to be applied with different voltages, there are attained an advantageous effect that viewing angle dependence is relaxed in the low gradation presentation and visibility is improved.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
