摘要： An active-matrix substrate includes: scanning signal lines; data signal lines; first storage capacitor wires; second storage capacitor wires; and pixels, disposed at intersections between the scanning signal lines and the data signal lines, each of which includes a plurality of sub-pixels. Each of the data signal lines is split into two parts at a region where the number of scanning signal lines intersecting the data signal line is ½ of the total number of scanning signal lines. A data signal line split section is formed on a region that does not overlap the second storage capacitor wires. This makes it possible to provide an active-matrix substrate, a display device, and a television receiver in each of which a data signal line split into two parts and a storage capacitor wire are hardly electrically short-circuited in the case of a combination of a split-screen structure and a multi-pixel structure.

摘要： Each picture element includes first and second sub-picture elements, each of which includes a liquid crystal capacitor and at least one storage capacitor. After a display voltage representing a certain grayscale level has been applied to the respective sub-picture element electrodes of the first and second sub-picture elements, a voltage difference ΔVα is produced between voltages to be applied to the respective liquid crystal capacitors of the first and second sub-picture elements by way of their associated storage capacitor(s). By setting the voltage difference ΔVα value of the blue and/or cyan picture element(s) to be smaller than that of the other color picture elements, shift toward the yellow range at an oblique viewing angle can be minimized.

摘要： A segmented-pixel liquid crystal display has a plurality of pixels of which each has three sub-pixels 10a-10c, namely one middle and two side sub-pixels, arranged next to one another in the column or row direction. The sub-pixels 10a-10c have different brightness levels when the pixel as a whole is in a given middle halftone state, and the middle sub-pixel 10a has the highest brightness level. This eliminates unnaturalness as is conventionally produced when an image with a straight border is displayed, and further improves the gamma characteristic.
