no. 1 Embodiment approach

[0035] Hereinafter, the liquid crystal device in the first embodiment of the present invention will be described with reference to the drawings. The liquid crystal device of this embodiment adopts a method called FFS (Fringe Field Switching, A liquid crystal device using a fringe field switching method.

[0036] Furthermore, the liquid crystal device of this embodiment is a color liquid crystal device provided with a color filter on a substrate, and one pixel is constituted by three sub-pixels that emit light of each color of R (red), G (green), and B (blue). Therefore, a display area constituting the smallest unit constituting a display is referred to as a "sub-pixel area", and a display area composed of a set of (R, G, B) sub-pixels is referred to as a "pixel display area".

[0037] FIG. 1 is a diagram showing a circuit configuration of a plurality of sub-pixel regions formed in a matrix and constituting a liquid crystal device according to the present embodiment. FIG. 2 i...

no. 2 Embodiment approach

[0100] Next, a second embodiment of the present invention will be described with reference to the drawings.

[0101] The difference between the liquid crystal device of this embodiment and the liquid crystal device of the first embodiment and the above-mentioned modified example is that the base portion 209a connecting the plurality of strip-shaped electrodes 209c is provided on adjacent strip-shaped electrodes 209c. The two ends of the shape electrode 209c. Therefore, constituent members such as the liquid crystal layer, the TFT array substrate 10 , the counter substrate 20 , the polarizing plates 14 and 24 constituting the liquid crystal device of the present embodiment are the same as those of the first embodiment described above. Therefore, in the following description, the description of the same parts as those of the first embodiment and the modified example will be omitted.

Abstract

The present invention provides a liquid crystal device which can do high-brilliance displaying in the FFS mode and the electronic device thereof. The invention comprises the following components: a first substrate and a second substrate facing each other with a liquid crystal layer held therebetween, a first electrode (19) and a second electrode (9) arranged at the side of the liquid crystal layer of the first substrate, the data line (6a) and the scanning line (3a) which are intersecting with one another at the side of the liquid crystal layer of the first substrate and a switching element (30); and the orientation of the liquid crystal molecule is controlled by the electric filed generated between the first electrode (19) and the second electrode (9). The first electrode (19) is arranged in the pixel displaying area surrounded by the data line and the scanning line; and the second electrode (9) comprises the following components: a plurality of electrodes extending in the direction intersecting to the data line (6a) and a connecting part (9a) which leads to that the end of at least one side of the adjacent branch electrode (9c) respectively electrically connects between each branch electrode (9c) openly; and an area which is plane-overlapped with the first electrode (19) in the pixel area.

Description

technical field [0001] The present invention relates to a liquid crystal device and electronic equipment. Background technique [0002] In liquid crystal devices using TN (Twisted Nematic, twisted nematic) liquid crystals, there has been a problem of narrow viewing angles in the past. In order to solve such problems, a fringe field switching (FFS) mode liquid crystal device has been proposed in which a first electrode and a second electrode are disposed on one of a pair of substrates sandwiching a liquid crystal layer, and The electric field (lateral electric field) between these first and second electrodes drives the liquid crystal layer. [0003] Patent Document 1 below discloses a liquid crystal device in which, in an FFS mode liquid crystal device, color shift is prevented by forming rectangular openings arranged at a predetermined inclination in a pixel electrode (second electrode). and the occurrence of disclination. [0004] [Patent Document 1] JP-A-2002-182230 ...
