[0029] figure 2 is a plan view illustrating the transflective LCD device 100 according to the first embodiment. image 3 is along figure 2 A cross-sectional view taken along the line I-I. Such as figure 2 and image 3 As shown, the transflective LCD device 100 includes: a first substrate 102 and a second substrate 110 facing each other at a predetermined interval; and a liquid crystal layer 150 formed between the first substrate 102 and the second substrate 110 . The first substrate 102 corresponds to a thin film transistor array substrate, and the second substrate 110 corresponds to a color filter array substrate. Each pixel area is divided into a reflective part and a transmissive part. And, the reflective portion is divided into a first region (reflective portion I) in which the pixel electrode is not formed and a second region (reflective portion II) in which the pixel electrode is formed. exist figure 2 , the second area 136 is located in the center of the upper le...

[0055] Figure 6 is a plan view illustrating a VA mode transflective LCD device 200 according to the second embodiment. combine with Figure 2 to Figure 5 Compared with the described first embodiment, the sizes of the reflective part and the transmissive part in the unit pixel area of the LCD device 200 are different. exist figure 2 , the pixel electrode 117 extends to about half of the pixel area. exist Figure 6 , the pixel electrode 117 extends to more than half of the pixel area.
[0056] The unit pixel area is divided into a reflective portion and a transmissive portion. Such as Figure 6 As shown, the reflective part occupies about 1 / 4 of the unit pixel area, and the transmissive part occupies about 3 / 4 of the unit pixel area. The pixel electrode 117 is formed in a predetermined portion of the reflective portion. The reflection part is divided into a first area and a second area, and the pixel electrode 117 is formed in the second area of the transmission par...

[0060] Figure 7 is a plan view illustrating a transflective LCD device 300 according to the third embodiment. Figure 8 is along Figure 7 A cross-sectional view taken along the line II-II. The transflective LCD device 300 has a VA mode (but it is not limited thereto), and is available in a normally black mode. In the third embodiment, a unit pixel area is divided into at least two areas, and the divided areas are rubbed in different directions, thereby forming a plurality of domains. In this embodiment, the opening pattern 117 a may not be formed in the pixel electrode 117 or the common electrode 115 . Alternatively or additionally, the rib 134 may not be formed on the pixel electrode 117 or the common electrode 115 .
[0061] Such as Figure 7 and Figure 8 As shown, the VA mode transflective LCD device 300 includes a first substrate 102 as a thin film transistor array substrate, a second substrate 110 as a color filter array substrate, and the first substrate 102 and...
