Please refer to Fig. 1, Fig. 2 and Fig. 4, it is worth mentioning that, when in order to one of adjacent two pel arrays 120 showing different colours activation during another not activation when wish does not show with the color that the second filter pattern 234 is corresponding for the display color corresponding with the first filter pattern 232 (display panel 1000), part display dielectric layer 130 in the R1 of region is driven, and the part display dielectric layer 130 in the R2 of region is not driven, by the design of W1≤W2>W3, the exhausted major part of light beam L by the part display dielectric layer 130 in the R1 of region and to the second filter pattern 234 transmission all can be stopped by conductive shading 140 and shielding pattern layer 220.Thus, the light beam L through the pel array 120 of activation just not easily passes second filter pattern 234 corresponding with the pel array 120 of non-activation, thus the colour mixture problem in known technology can be improved.In addition, in the embodiment in figure 1, because conductive shading 140 and the first transparency electrode 150 first is 152 in electrical contact, therefore the first transparency electrode 150 of common electrode is used as and the equivalent distances between the set of conductive shading 140 and data line DL increases, thus the stray capacitance between common electrode and data line DL can reduce, and contribute to the performance boost of display panel 1000.
Fig. 5 illustrates the NTSC ratio of the display panel of NTSC (the National Television System Committee) ratio of the display panel of Fig. 1 when shielding pattern layer produces colour cast with great visual angle and a comparative example when shielding pattern layer produces colour cast with great visual angle.The difference of the display panel of comparative example and the display panel of Fig. 1 is mainly: the display panel of comparative example does not have the conductive shading 140 of the display panel of Fig. 1.Please refer to Fig. 5, curve S 100 represents the NTSC ratio of the display panel 1000 of Fig. 1 under each visual angle, and curve S 200 represents the NTSC ratio of the display panel of comparative example under each visual angle.Comparison curves S100, S200 are known, the display panel 1000 of Fig. 1 when producing colour cast with great visual angle the NTSC ratio of (being such as greater than the visual angle of 30 degree) apparently higher than the display panel of comparative example at the NTSC ratio of the situation of colour cast with great visual angle of corresponding angle.Specifically, under identical angle with great visual angle, such as, at visual angle when 40 degree, the NTSC ratio of the display panel 1000 of Fig. 1 is greater than more than 75%, and the NTSC ratio of the display panel of comparative example is then less than 75%.It can thus be appreciated that the setting of the conductive shading 140 of one embodiment of the invention can improve the problem of colour mixture in known technology significantly, and still can maintain higher NTSC ratio when colour cast with great visual angle.
In sum, in the display panel of one embodiment of the invention, the width of the first light shielding part of light-shielding pattern is W1, and the width of conductive shading is W2, and the live width of data line is W3, and W1≤W2>W3.By the design of W1≤W2>W3, by being transmitted to the light beam of second filter pattern corresponding with the pel array of closing with part display medium corresponding to pel array opened, exhausted major part can be stopped by conductive shading and shielding pattern layer and not easily pass the second filter pattern, thus the colour mixture problem in known technology can be improved.
