Abstract:
1. A transflective liquid crystal display device, comprising: a liquid crystal display panel including a pair of substrates and a liquid crystal layer held between the pair of substrates, the liquid crystal display panel having a plurality of sub-pixels each having a transmissive section and a reflective section, each of the sub-pixels having a first electrode of a first electrode type formed over one of the pair of substrates and a second electrode of a second electrode type formed over the one of the pair of the substrates, wherein the first electrode of the first electrode type is a planar electrode extending in a direction of a scan line, the second electrode is an electrode having a plurality of linear portions, and an insulating layer is disposed between the first electrode and the second electrode, a third electrode of the first electrode type extending in the direction of the scan line is located in a direction that is perpendicular to the direction of the scan line from the first electrode such that a gap exists between the first and third electrodes; a voltage applied to the first electrode is different from a voltage applied to the third electrode, the first electrode and the second electrode generate an electric field to drive a liquid crystal in the liquid crystal layer, the liquid crystal layer is of a positive type liquid crystal, an initial orientation direction of the liquid crystal in the liquid crystal layer is perpendicular to the direction in which the scan line extends or is angularly displaced within ±2 degrees clockwise with respect to the direction perpendicular to the direction in which the scan line extends, and the initial orientation direction of the liquid crystal in the liquid crystal layer forms an oblique angle with a direction of the linear portions of the second electrode.
