It is the schematic top plan view (position of 11 dotted line frame of corresponding diagram of the first substrate 50 of the present embodiment 4 please also refer to Figure 12 Set), wherein Figure 12 also clipped element (such as pixel electrode and third insulating layer) skill of the invention is presented to become apparent from Art feature.As shown in figure 12, embodiment 4 is similar to Example 1, and the first metal gasket 509 and the second metal gasket 510 pass through two second The semiconductor layer 503 is electrically connected in contact hole 511, and first contact hole 508 and two second contact hole 511 are located at this Between first scan line 505 and second scan line 505 '.The other elements structure of the present embodiment 4 and configuration and embodiment 1 are big The schematic cross-sectional view of similar, to be unfolded along the C-C ' cutting line of Figure 12 first substrate 50 is caused to be the same as Fig. 5, it herein will no longer It repeats.

Figure 13 A is please referred to, is the pixel polarity schematic diagram using the first substrate 50 ' of known line structure design.Such as figure Shown in 13A, since same data line 507 ' is to input electric signal with fixed positive-negative polarity to each pixel, therefore every row pixel It is polarity having the same, and the pixel between not going together has different polarity.Due to adjacent same column pixel polarity that This is on the contrary, each pixel is easy to produce crosstalk (cross-talk) to each other.It is the embodiment of the present invention conversely, please referring to Figure 13 B The pixel polarity schematic diagram of 4 first substrate 50.Though the data line 507 of the present embodiment 4 still inputs news with fixed positive-negative polarity Number to each pixel, so because being designed using the line configuring of the present embodiment 4, driven in a manner of row reversion (column inversion) Dynamic pixel, the pixel polarity of adjacent same column is mutually the same, is not likely to produce crosstalk.Therefore, the first substrate 50 of the present embodiment 4 has The advantages of low-power consumption, low crosstalk.

It is the second substrate 60 of the first substrate 50 of corresponding diagram 11 please continue to refer to Figure 14, wherein Figure 14 is to be overlapped The second substrate 60 is presented in the mode of 50 local line of first substrate of Figure 11, with the black square to become apparent from display the second substrate Relative positional relationship between battle array layer and pixel group and the route of first substrate.Since the present embodiment 4 is by adjusting first base Plate 50 matches line position and its structure, reduces the active member of sub-pixel switch, therefore as shown in figure 14, as colorized optical filtering The second substrate 60 of plate base can appropriate adjustment have in the corresponding first substrate 50 it is black at the opaque active member such as this The position of color matrix layer, and the corresponding pixel unit of the sub-pixel of adjacent and unshared same first contact hole switch is configured For homochromy pixel group, ratio shared by integral black matrix layer is reduced and the function of the aperture opening ratio that improves display panel to reach Effect.Therefore as shown in figure 14, in embodiment 4, the second substrate 60 as colored filter substrate does not include at least three not The pixel group 601 of same color (such as red, green, blue), each pixel group 601 include two adjacent to each other and same colors and along this The pixel unit (601A, 601B and 601C) of one direction arrangement, wherein in Yu Suoshu pixel group 601, first black matrix" Layer I-I ' is positioned at the pixel group 601 between and along a first direction (X-direction in such as figure) extension, and second black matrix" Layer II-II ' is between two sets of adjacent pixels 601.Further, since adjacent pixel unit (601A, 601B or 601C) is phase Same color is not required to avoid colour mixture, therefore can be not required to be arranged between adjacent and homochromy pixel unit (601A, 601B or 601C) Second black-matrix layer II-II ' (such as between pixel unit 601A) reaches and reduces ratio shared by integral black matrix layer, mentions The aperture opening ratio of high display panel.Furthermore though the present embodiment 4 is to be painted pixel unit 601A with rectangle, as long as can so reach known The demand and the present invention of black-matrix layer improve the effect of aperture opening ratio, and the black-matrix layer of any shape all can be used, therefore this hair The bright shape for being not specially limited pixel unit.Furthermore pixel group included by the second substrate 60 of the present embodiment 4 is removed Outside red, green and blue three-color pixel group, fields tool usually intellectual also can be adjusted to red, green, blue according to demand And the pixel group of white four kinds of colors, the present invention are not specifically limited thereto.

It is only for the sake of illustration for above-described embodiment, and the interest field that the present invention is advocated certainly should be with right Subject to described in claimed range, not just the above examples.
