no. 1 Embodiment approach
[0066] Returning to FIG. 3 , in the liquid crystal device of this embodiment, a pair of scanning lines 71 and 72 corresponding to a pair of pixel electrodes 91 and 92 adjacent to the extending direction of the first data line 61 are arranged on the first data line 61 . A pair of pixel electrodes 91, 92 are sandwiched in the extending direction of the first data line 61, and a plurality of TFT elements 31, 32, 33 corresponding to the plurality of pixel electrodes 91, 92, 93 arranged in the extending direction of the first data line 61 are arranged. The adjacent data lines 61 and 62 are alternately connected to one data line 61 and the other data line 62 along the extending direction of the data lines 61 and 62 on opposite sides of the adjacent data lines 61 and 62 .
[0067] Here, attention is paid to a pair of pixel electrodes 91 and 92 arranged adjacent to each other in the extending direction of the first data line 61 . In this embodiment, the first scanning line 71 correspo...
no. 2 Embodiment approach
[0078] Next, the liquid crystal device of the second embodiment will be described.
[0079] 9 is an explanatory diagram of a planar structure of a liquid crystal device according to a second embodiment. The liquid crystal device of the second embodiment is different from the first embodiment in that the second light shielding film 24 covering the region where the pixel electrodes are not formed is formed between the pair of pixel electrodes 91 and 92 . In addition, the detailed description of the part of the same structure as 1st Embodiment is abbreviate|omitted.
[0080] Also in the second embodiment, a pair of pixel electrodes 91 and 92 are adjacently arranged without interposing a scanning line. However, in the region where the pixel electrode is not formed between the pair of pixel electrodes 91 and 92 , the alignment control force of the liquid crystal at the time of application of the selection voltage becomes weak, and alignment disorder (disclination) occurs. As a re...
no. 3 Embodiment approach
[0083] Next, the liquid crystal device of the third embodiment will be described.
[0084] 10 is an explanatory diagram of a planar structure of a liquid crystal device according to a third embodiment. The liquid crystal device of the third embodiment differs from the first embodiment in that the second scanning lines 72 and the third scanning lines are arranged in layers so as to overlap in a planar view. In addition, detailed descriptions of parts having the same configuration as those in the above-described embodiments are omitted.
[0085] Fig. 11 is a side cross-sectional view taken along line B-B of Fig. 10 . FIG. 11 shows the cross-sectional structures of the third TFT element 33 and the fourth TFT element 34 . A third gate electrode 37 a and a fourth gate electrode 37 b are formed on the surface of the gate insulating film 2 . Furthermore, an interlayer insulating film 4a is formed so as to cover each gate electrode, and a third scanning line 73 is formed on the sur...
