In addition, the display panel 100 may further include a counter substrate 150 and a display medium layer 160 , wherein the display medium layer 160 is located between the substrate 110 and the opposite substrate 150 . The display medium layer 160 may change its dumping state according to the potential difference between the first electrode 20 and the second electrode 30, thereby causing the display panel 100 to display different gray scales. For example, the display medium layer 160 is, for example, a liquid crystal layer.

Furthermore, the display panel 100 may further include a color filter layer 170, a black matrix 180, and a protective layer 190. In this embodiment, the black matrix 180, the color filter layer 170, and the protective layer 190 are sequentially disposed on the opposite substrate 150, for example, and the black matrix 180, the color filter layer 170, and the protective layer 190 are located on the display medium layer. 160 is between the opposite substrate 150. The black matrix 180 partially overlaps the first electrode 20 and the second electrode 30 in each pixel region P on the vertical projection of the substrate 110, and the black matrix 180 shields the scan lines 122 and the data lines 124 in the pixel array 120. And the surrounding lines that are not shown.

The color filter layer 170 is disposed on the black matrix 180 and the opposite substrate 150, and the protective layer 190 covers the color filter layer 170 over the entire surface to protect the color filter layer 170. The color filter layer 170 includes, for example, a plurality of color filter patterns of different colors to achieve full colorization. For example, the color filter layer 170 includes a plurality of red filter patterns (not shown), a plurality of green filter patterns 172, and a plurality of blue filter patterns 174, wherein the red filter patterns correspond to the first sub-pixels. 126A is set, the green filter pattern 172 is set corresponding to the second sub-pixel 126B, and the blue filter pattern 174 is corresponding to the third sub-pixel 126C. The first sub-pixel 126A is a red sub-pixel, the second sub-pixel 126B is a green sub-pixel, and the third sub-pixel 126C is a blue sub-pixel.

The first side S1 of the first portion 32 of the first sub-pixel 126A, the second sub-pixel 126B, and the second sub-pixel 126C of the third sub-pixel 126C and the first electrode 20 are adjacent to the second portion of the first portion 32 The side S2 has a first pitch I1, a second pitch I2, and a third pitch I3 in the vertical projection direction, respectively. In the prior art, the first pitch I1, the second pitch I2, and the third pitch I3 are all the same. However, when the display panel is equipped with a white light backlight, there is a problem that the display color is yellowish. Therefore, it is required to be used with a blue backlight, and the yellow light is mixed by the blue light to obtain white light conforming to the white point specification. However, this architecture tends to drastically reduce the overall light transmittance of the liquid crystal display.

In view of this, the first pitch I1 and the second pitch I2 are the same, and the third pitch I3 is smaller than the first pitch I1. The white point is blue-shifted by reducing the third pitch I3 of the first electrode 20 of the third sub-pixel 126C and the first portion 32 in the vertical projection direction. Therefore, the display panel 100 can be free from the limitation of the backlight with a bluish blue, thereby improving the problem that the luminous efficiency is greatly reduced due to the backlight from the bluish. On the other hand, the liquid crystal display to which the display panel 100 of the present embodiment is applied can pass through a backlight with a high luminous efficiency, such as a backlight of a light-emitting diode of the Lextar PS06W13 V2, to effectively improve the overall light transmittance. . In this embodiment, the third pitch I3 may be greater than or equal to zero. That is, the first side S1 of the first portion 32 may be aligned with the first side 20 of the first portion 32 adjacent to the second side S2 of the first portion 32.

In practice, the above method of reducing the third pitch I3 can increase the third sub- The width of the first electrode 20 of the pixel 126C is parallel to the extending direction D1 of the scanning line 122 to reduce the distance between the first side S1 and the second side S2 in the vertical projection direction. As such, the width W20C of the first electrode 20 of the third sub-pixel 126C in the extending direction D1 parallel to the scan line 122 will be greater than the second sub-pixel 126B (or the first sub-pixel 126A) in parallel with the scan line 122. The width W20B in the direction of extension D1. Here, the first electrode 20 of the third sub-pixel 126C may simultaneously extend toward the extending direction D1 and the first portion 32 of the third sub-pixel 126C extends (ie, extends in the opposite direction of the extending direction D1).

The above embodiment is to reduce the white point by shifting the third pitch I3, but the present invention is not limited thereto. 4 is a partial cross-sectional view of a display panel in accordance with a second embodiment of the present invention. Specifically, FIG. 4 is only a schematic cross-sectional view of the third sub-pixel. Referring to FIG. 4, the display panel 100A of the present embodiment is substantially the same as the display panel 100 of FIG. 3, and the same components are denoted by the same reference numerals, and the relative arrangement relationship between the components or the functions and functions thereof will not be described herein. .

The main difference from the first embodiment is that the present embodiment shifts the white point blue by increasing the thickness of the insulating layer 130A in the third sub-pixel 126C. In detail, the first pitch I1 (indicated in FIG. 1), the second pitch I2, and the third pitch I3 of the embodiment are the same, and the width W20C of the first electrode 20 of the third sub-pixel 126C is the same as the second. The sub-pixel 126B (or the first sub-pixel 126A) has a width W20B. However, the insulating layer 130A between the first electrode 20 of the third sub-pixel 126C and the substrate 110 has a first thickness H1, the first electrode 20 of the first sub-pixel 126A and the first of the second sub-pixel 126B. Each insulating layer 130A between the electrode 20 and the substrate 110 has a second thickness H2, and the first thickness H1 is greater than the second thickness H2. For example, the difference in thickness between the first thickness H1 and the second thickness H2 is between 0.1 and 0.6 microns.

The material of the insulating layer 130A may be an inorganic material (for example, yttria, tantalum nitride, yttrium oxynitride, lanthanum aluminum oxide or a stacked layer of at least two materials described above), an organic material, or a combination thereof. Further, the insulating layer 130A may be a single layer structure, or as shown in FIG. 5, the insulating layer 130B may also be a multilayer stacked structure.

The display panels of Table 1 and Figure 4 will be described below. The values in Table 1 are measured after the display panel is combined with a backlight to form a liquid crystal display, wherein (Rx, Ry), (Gx, Gy), (Bx, By) are respectively a liquid crystal display displaying a red screen, a green screen, and The color coordinate values measured in the blue screen, RY, GY, and BY are the luminance values of the red screen, the green screen, and the blue screen, respectively. (Wx, Wy) are the color coordinate values measured by the liquid crystal display displaying the white screen. And WY is the brightness value of the white screen. TR% is the light transmittance of the display panel as a whole. Eff _BL is the power of the backlight, and Eff _D is the overall light transmittance of the liquid crystal display. In the comparative example, the first pitch I1 (see FIG. 1), the second pitch I2, and the third pitch I3 are both 2 micrometers, and the first sub-pixel 126A (see FIG. 1), the second sub-pixel 126B, and the first The insulating layer 130A in the three sub-pixels 126C has the same thickness. Experimental Example 1, Experimental Example 2, and Experimental Example 3 were the same pitch design as the comparative examples, but the first thickness H1 of Experimental Example 1, Experimental Example 2, and Experimental Example 3 was 0.2 μm and 0.4 μm more than the second thickness H2, respectively. 0.6 microns.

It is apparent from Table 1 that when the first thickness H1 is greater than the second thickness H2, the white point is blue-shifted, and when the thickness difference between the first thickness H1 and the second thickness H2 is in the range of 0.1 to 0.6 μm, The greater the difference in thickness, the more pronounced the white point blue shift phenomenon. In addition, the light transmittance of the liquid crystal display of the experimental examples 1, 2, and 3 can be effectively improved by using a backlight with high luminous efficiency.

The first embodiment of FIGS. 1 to 3 is to modulate the distance between the first electrode of the third sub-pixel and the first portion in the vertical projection direction to shift the white point blue. The second embodiment of Figures 4 and 5 is to increase the thickness of the insulating layer in the third sub-pixel to shift the white point blue. However, the invention is not limited to the above. Figure 6 is a partial cross-sectional view showing a display panel in accordance with a third embodiment of the present invention. Specifically, FIG. 6 is only a schematic cross-sectional view of the second and third sub-pixels. Referring to FIG. 6 , the display panel 100C of the present embodiment is substantially the same as the display panel 100 of FIG. 3 and the display panel 100A of FIG. 4 , and the same components are denoted by the same reference numerals, and the relative relationship between the components will not be described herein. Configuration relationship or its role, efficacy.

The main difference from the first and second embodiments is that the third interval I3 of the first electrode 20 and the first portion 32 in the vertical projection direction and the third increase are simultaneously reduced by simultaneously reducing the third sub-pixel 126C. The thickness of the insulating layer 130A in the sub-pixel 126C (so that the first thickness H1 is greater than the second thickness H2) causes the white point to be blue-shifted.

The display panels of Table 2 and Figure 6 will be described below. In the comparative example, the first pitch I1 (see FIG. 1), the second pitch I2, and the third pitch I3 are both 2 micrometers, and the first sub-pixel 126A (see FIG. 1), the second sub-pixel 126B, and the first The insulating layer 130A in the three sub-pixels 126C has the same thickness. Experimental Example 1, Experimental Example 2, and Experiment The first thickness H1 of Example 3 was 0.2 μm more than the second thickness H2, and the difference was that the third pitch I3 was gradually decreased from Experimental Example 1 to Experimental Example 3. Specifically, Experimental Example 1 and the comparative example were designed with the same pitch, and the third pitch I3 of Experimental Example 2 was 1 μm, and the third pitch of Experimental Example 3 was 0.

As is apparent from Table 2, when the first thickness H1 is larger than the second thickness H2, the white point is blue-shifted, and as the third pitch I3 is smaller, the brightness of the blue screen is brighter (see BY line). In addition, through the backlights with high luminous efficiency, the liquid crystal displays of the experimental examples 1, 2, and 3 can effectively improve the overall light transmittance of the liquid crystal display.

In summary, the display panel of the present invention reduces the distance between the first electrode of the third sub-pixel and the first portion in the vertical projection direction, or increases the thickness of the insulating layer in the third sub-pixel, or The white point is blue-shifted by reducing the distance between the first electrode of the third sub-pixel and the first portion in the vertical projection direction and increasing the thickness of the insulating layer in the third sub-pixel. Therefore, the display panel of the present invention can be unconstrained with a bluish backlight to conform to the white point specification, thereby improving the problem that the light transmittance is greatly reduced due to the blue light from the bluish backlight. On the other hand, the liquid crystal display to which the display panel of the present invention is applied can pass through a backlight with high luminous efficiency to effectively improve the overall light transmittance.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and any one of ordinary skill in the art can make some changes and refinements without departing from the spirit and scope of the present invention.
