first embodiment

[0026]FIG. 1 illustrates a PSVA mode LCD panel according to the first embodiment of the present disclosure. A display panel includes a first substrate S1, a second substrate S2 disposed oppositely to the first substrate S1, and a liquid crystal layer LC disposed between the first substrate S1 and the second substrate S2. For example, the first substrate S1 and the second substrate S2 are a TFT substrate and a CF substrate, and this structure is taken for illustrating the related configuration of the embodiment. However, the disclosure is not limited to this structure and illustrated details.

[0027]In one embodiment, the first substrate S1 comprises a first base plate 11, a first transparent conductive layer13 formed on the first base plate 11, an insulating layer 14 formed on the first transparent conductive layer 13, and a second transparent conductive layer 15 formed on the insulating layer 14, as shown in FIG. 1. The first substrate S1 also comprises a plurality of transistors, an...

second embodiment

[0040]This disclosure can be applied to a low color shift (LCS) mode LCD panel. Please refer to FIG. 5A, which illustrates a single pixel region of a convention LCS mode LCD panel. As shown in FIG. 5A, there is a bright region A and a dark region B in each pixel region for compensating the color shifting when the display panel is viewed from the side. In the second embodiment, the bright region and the dark region in each pixel region of the LCS mode LCD panel are created by partially overlapping the upper and lower electrodes. FIG. 5B and FIG. 5C illustrate a single pixel region of a LCS mode LCD panel according to the second embodiment of the present disclosure, respectively. Please refer to FIG. 1 and related descriptions above for the three-electrode design (i.e. configuration of the first transparent conductive layer 13 / the second transparent conductive layer 15 / the third transparent conductive layer 23) of the embodiment. As shown in FIG. 5B and FIG. 5C, the full MITO film (i....

third embodiment

[0048]In the first and second embodiments, the full MITO film is exemplified for illustrating the electrode design. However, the disclosure is not limited thereto. The MITO film positioned below the patterned TITO film (i.e. the second transparent conductive layer 15) can be a patterned ITO film with plural slits. FIG. 10 depicts the top views of an MITO pattern and a TITO pattern in a single pixel region of a display panel according to the third embodiment of the disclosure. As shown in FIG. 10, the first transparent conductive layer 13′ has several first slits 13S, the second transparent conductive layer 15′ has several second slits 15S, and the positions of the first slits 13S are staggered from the positions of the second slits 15S. Also, the extending directions of the first slits 13S are identical to the extending directions of the second slits 15S.

[0049]According to the aforementioned descriptions, the three-electrode design of the embodiment (i.e. the first transparent condu...

Abstract

A display panel includes a first substrate, a second substrate opposite to the first substrate, and a liquid crystal layer positioned between the first substrate and the second substrate. The first substrate includes a first base plate, plural scan lines and plural data lines formed on the first base plate and intersected each other, wherein two adjacent scan lines and two adjacent data lines define a pixels region. Each pixel region includes a first transparent conductive layer formed above the first base plate, an insulating layer formed on the first transparent conductive layer, and a second transparent conductive layer formed on the insulating layer. The second substrate includes a second base plate and a third transparent conductive layer formed on the second base plate.
