Description

Display device TECHNICAL FIELD

[0001] The present disclosure relates to a display device, and particularly relates to a cholesteric liquid crystal display device. BACKGROUND

[0002] Cholesteric liquid crystal (ChLCD) technology is compatible with the existing liquid crystal display (LCD) manufacturing method, and has become the mainstream of display technology in recent years because of its advantages of easy realization of full color, high reflectivity, power saving, eye protection and the like.

[0003] In the application of active array cholesteric liquid crystal display, the liquid crystal is mainly controlled by the electric field generated between the common electrode of the upper substrate and the pixel electrode of the lower substrate to rotate the liquid crystal molecules. However, there is a voltage difference between the scanning line, the data line and the pixel electrode, which forms an electric field to rotate the liquid crystal molecules, causing the problem of light leakage of the pixel in the dark state. Therefore, in order to improve the contrast ratio, a black matrix (BM) must be used for shading. Because there is a large overlapping area between the black matrix and the pixel electrode, the improvement of the aperture ratio is greatly limited.

[0004] In addition, since the full-color cholesteric liquid crystal display is formed by sequentially bonding three display panels of red, green and blue through optical clear adhesive (OCA), the improvement of the aperture ratio of the active array cholesteric liquid crystal display is more important than that of the traditional liquid crystal display.

[0005] Therefore, there is a lack of a high-aperture full-color active array cholesteric liquid crystal display device in the market, and relevant manufacturers are seeking solutions. SUMMARY

[0006] The purpose of the present disclosure is to provide a display device which can minimize the shading width of the black matrix by the setting of the electric field shielding electrode, and further improve the aperture ratio of the display device.

[0077] Embodiments of the present disclosure will be described below with reference to the accompanying drawings. For the sake of clear description, many practical details will be described in the following description. However, it should be understood that these practical details are not intended to limit the present disclosure. That is, in some embodiments of the present disclosure, these practical details are not necessary. In addition, for the sake of simplifying the drawings, some conventional structures and elements will be shown in a simple schematic manner in the drawings; and repeated elements can be indicated using the same reference numerals.

[0078] Furthermore, when an element (or unit or module etc.) is referred to as being "connected" to another element, it can be directly connected to the other element or indirectly connected to the other element with intervention of other elements therebetween. When it is specifically stated that an element is "directly connected" to another element, there is no other element therebetween. The terms first, second, third etc. are merely used to describe different elements and do not limit the elements themselves. Thus, a first element can also be referred to as a second element. The combination of elements / units / circuits in the present disclosure is not a combination of elements / units / circuits commonly known in the art, and the combination of elements / units / circuits cannot be easily completed by one of ordinary skill in the art based on whether the elements / units / circuits are existing or not.

[0079] Referring to FIG. 1, which is a schematic diagram of a display device according to a first embodiment of the present disclosure. The display device 100 comprises a first display panel B, a second display panel G and a third display panel R.

The first display panel B, the second display panel G and the third display panel R are sequentially stacked, and the first color, the second color and the third color are different from each other. In the first embodiment, any one of the first display panel B, the second display panel G and the third display panel R is a cholesteric liquid crystal panel, and the first color, the second color and the third color are a blue color, a green color and a red color respectively, but the present disclosure is not limited thereto.

[0080] As shown in FIG. 1, the first display panel B comprises a first black matrix 5a, the second display panel G comprises a second black matrix 5b, and the third display panel R comprises a third black matrix 5c. In addition, any one of the first display panel B, the second display panel G and the third display panel R further comprises an upper substrate 1, a protective layer 2, an upper plate common electrode 3, a frame glue 4, a plurality of pixel modules (not labeled), a lower substrate 12 and a light absorption plate 13. Each pixel module comprises a black matrix (i.e. the first black matrix 5a, the second black matrix 5b and the third black matrix 5c), a cholesteric liquid crystal 6, a pixel electrode 7, a passivation layer 8, a data line 9, a scan line 10 (not shown in the figure) and a field shielding electrode 11. The upper substrate 1, the protective layer 2 and the upper plate common electrode 3 are sequentially stacked on one side of the plurality of pixel modules along a direction (i.e. the z-axis direction z of FIG. 1), the lower substrate 12 is arranged on the other side of the plurality of pixel modules relative to the upper substrate 1 along the z-axis direction z, and the frame glue 4 is arranged at both ends of the plurality of pixel modules along an x-axis direction x. In the first embodiment, the upper substrate 1 and the lower substrate 12 can be glass or a flexible soft substrate such as plastic; the frame glue 4 can have various anisotropic conductive gold balls; and the passivation layer 8 can be a gate passivation layer, but the present disclosure is not limited thereto.

[0081] The pixel electrode 7 is disposed below one of the first black matrix 5a, the second black matrix 5b and the third black matrix 5c, the data line 9 and the scan line 10 are disposed below the pixel electrode 7, the scan line 10 is perpendicular to the data line 9 (as shown in FIG. 3A), and the electric field shielding electrode 11 is partially disposed below the data line 9. The pixel module is an active array, and the switching element (not labeled separately) of the active array is a thin film transistor (TFT), including but not limited to an amorphous silicon (a-Si) TFT, an oxide semiconductor TFT (such as IGZO), or a low-temperature polysilicon TFT.

[0082] Referring to FIGS. 1, 2A and 2B, wherein FIG. 2A is a top view showing the first black matrix of the first embodiment of the present disclosure, and FIG. 2B is a top view showing the second black matrix and the third black matrix of the first embodiment of the present disclosure. The first black matrix 5a completely shields the data line 9, the scan line 10 and the electric field shielding electrode 11 of the first display panel B along the z-axis direction z (as shown in FIGS. 4A, 5A and 6A, the first black matrix 5a shields the first electric field shielding electrode 11a, the second electric field shielding electrode 11b and the third electric field shielding electrode 11c). The second black matrix 5b and the third black matrix 5c respectively shield a part of the data line 9 and a part of the electric field shielding electrode 11 of the second display panel G along the z-axis direction z (as shown in FIGS. 7A, 8A and 9A, the second black matrix 5b and the third black matrix 5c shield a part of the first electric field shielding electrode 11a, the second electric field shielding electrode 11b and the third electric field shielding electrode 11c), and completely shield the scan line 10.

[0083] The first black matrix 5a, the second black matrix 5b and the third black matrix 5c are used to avoid the photo-induced leakage current formed after the TFT channel is irradiated by light, which causes the switching element to fail. The electric field shielding electrode 11 is used to reduce the electric field intensity of the data line 9 on the pixel electrode 7. Specifically, the patterns of the first black matrix 5a, the second black matrix 5b and the third black matrix 5c can completely shield or partially shield the data line 9, the scan line 10 and the electric field shielding electrode 11, and the electric field shielding electrode 11 can reduce the electric field intensity while providing a light transmission area to increase the aperture ratio. In this way, the width and degree of light leakage are reduced, and the aperture ratio and contrast are greatly improved.

[0084] It should be particularly pointed out that in the first embodiment, the electric field shielding electrode 11 can be a penetrating type, a reflective type or a semi-penetrating and semi-reflective type. According to the above embodiment, the following specific embodiments are proposed in detail with reference to the accompanying drawings.

[0085] Referring to FIG. 3A, FIG. 3B and FIG. 3C, FIG. 3A is a top view showing a first electric field shielding electrode of the present disclosure; FIG. 3B is a top view showing a second electric field shielding electrode of the present disclosure; and FIG. 3C is a top view showing a third electric field shielding electrode of the present disclosure. As shown in FIG. 3A, the first electric field shielding electrode 11a is a transmissive type, made of a light-transmissive conductive material, and the light-transmissive conductive material can be indium tin oxide (ITO) or indium zinc oxide (IZO). As shown in FIG. 3B, the second electric field shielding electrode 11b is a reflective type, made of a metal material, and the metal material is not light-transmissive. As shown in FIG. 3C, the third electric field shielding electrode 11c is a semi-transmissive and semi-reflective type, and the third electric field shielding electrode 11c comprises a horizontal electrode portion 111 and a vertical electrode portion 112.

The vertical electrode portion 112 is perpendicular to the horizontal electrode portion 111, and parallel to the data line 9, and the vertical electrode portion 112 is made of a light-transmissive conductive material, and the light-transmissive conductive material can be indium tin oxide (ITO) or indium zinc oxide (IZO).

[0086] Referring to FIG. 1, FIG. 3A, FIG. 4A, FIG. 4B and FIG. 4C, FIG. 4A is a schematic view showing a first pixel module of the present disclosure; FIG. 4B is a schematic view showing a cross-sectional view along line A-A of FIG. 4A; and FIG. 4C is a schematic view showing a cross-sectional view along line B-B of FIG. 4A. The first display panel B can comprise a first pixel module m1, and the first pixel module m1 comprises a first black matrix 5a and a first electric field shielding electrode 11a which is a transmissive type. In the first pixel module m1, the first black matrix 5a completely shields the data line 9, the scan line 10 and the first electric field shielding electrode 11a along the z-axis direction z.

[0087] Further explanation, referring to FIG. 4B and FIG. 4C, the solid arrowed line is the path of the incident light, and the dashed arrowed line is the path of the reflected light. As shown in FIG. 4B and FIG. 4C, the incident light can only enter and exit from the edge of the first black matrix 5a. In addition, the width of the projection overlapping portion between the pixel electrode 7 and the first electric field shielding electrode 11a is ≥1.5 microns, and the pattern edge distance of the projection overlapping area between the data line 9 and the partial first electric field shielding electrode 11a is ≥1.5 microns, but the present disclosure is not limited thereto.

[0088] Referring to FIG. 4A, the first black matrix 5a, the pixel electrode 7, the data line 9, and the first electric field shielding electrode 11a are stacked along the z-axis direction z to form a first light passing hole P1. The first light passing hole P1 has a first light passing hole diameter Pa1 along a first radial direction (i.e., the x-axis direction x) and a second light passing hole diameter Pa2 along a second radial direction (i.e., the y-axis direction y). The first radial direction is perpendicular to the second radial direction, and both the first radial direction and the second radial direction are perpendicular to the z-axis direction z. The first light passing hole diameter Pa1 and the second light passing hole diameter Pa2 are determined by the first black matrix 5a.

[0089] In this way, by adjusting the first light passing hole diameter Pa1 and the second light passing hole diameter Pa2 to increase the size of the first light passing hole P1 and to recycle the reflected light, a higher aperture ratio can be provided.

[0090] Referring to FIGS. 1, 3B, 5A, 5B, and 5C, FIG. 5A is a schematic diagram illustrating a second pixel module of the present disclosure, FIG. 5B is a schematic diagram illustrating a cross-sectional view along line A-A of FIG. 5A, and FIG. 5C is a schematic diagram illustrating a cross-sectional view along line B-B of FIG. 5A. The first display panel B can further include a second pixel module m2 including the first black matrix 5a and a reflective second electric field shielding electrode 11b. In the second pixel module m2, the first black matrix 5a completely shields the data line 9, the scan line 10, and the second electric field shielding electrode 11b along the z-axis direction z.

[0091] Further, referring to FIGS. 5B and 5C, the solid arrowed line is the path of the incident light, and the dashed arrowed line is the path of the reflected light. As shown in FIGS. 5B and 5C, the incident light can only enter and exit from the edge of the first black matrix 5a. In addition, the width of the projection overlap between the pixel electrode 7 and the second electric field shielding electrode 11b is greater than or equal to 1.5 microns, and the pattern edge distance of the projection overlap between the data line 9 and the second electric field shielding electrode 11b is greater than or equal to 1.5 microns, but the present disclosure is not limited thereto.

[0092] Referring to FIGS. 1, 3C, 6A, 6B, and 6C, FIG. 6A is a schematic diagram illustrating a third pixel module of the present disclosure, FIG. 6B is a schematic diagram illustrating a cross-sectional view along line A-A of FIG. 6A, and FIG. 6C is a schematic diagram illustrating a cross-sectional view along line B-B of FIG. 6A. The first display panel B can further include a third pixel module m3 including the first black matrix 5a and a semi-transmissive and semi-reflective third electric field shielding electrode 11c. In the third pixel module m3, the first black matrix 5a completely shields the data line 9, the scan line 10, and the third electric field shielding electrode 11c along the z-axis direction z.

[0093] Further explanation, referring to FIG. 6B and FIG. 6C, the arrowed solid line is the path of the incident light, and the arrowed dashed line is the path of the reflected light. As shown in FIG. 6B and FIG. 6C, the incident light can only enter and exit from the edge of the first black matrix 5a. In addition, the width of the projection overlapping portion between the pixel electrode 7 and the first black matrix 5a is ≥1.5 microns, and the edge distance of the projection overlapping area between the data line 9 and the partial third electric field shielding electrode 11c is ≥1.5 microns, but the present disclosure is not limited thereto.

[0094] Referring to FIG. 1, FIG. 3A, FIG. 7A, FIG. 7B, and FIG. 7C, wherein FIG. 7A is a schematic diagram illustrating a fourth pixel module of the present disclosure; FIG. 7B is a schematic diagram illustrating a cross-sectional view along line A-A in FIG. 7A; and FIG. 7C is a schematic diagram illustrating a cross-sectional view along line B-B in FIG. 7A. The second display panel G or the third display panel R can further include a fourth pixel module m4 including a second black matrix 5b or a third black matrix 5c and a first electric field shielding electrode 11a in a transmissive mode. In the fourth pixel module m4, the second black matrix 5b or the third black matrix 5c shields a portion of the data line 9 (as shown in block S of FIG. 7A) and a portion of the first electric field shielding electrode 11a (as shown in the long side L of FIG. 7A, which is parallel to the scan line 10) along the z-axis direction z.

[0095] Further explanation, referring to FIG. 7B and FIG. 7C, the arrowed solid line is the path of the incident light, and the arrowed dashed line is the path of the reflected light. The arrow on the surface of the data line 9 indicates the reflection of the light by the metal, and the arrow size represents the relative intensity. As shown in FIG. 7B and FIG. 7C, because the first electric field shielding electrode 11a of the fourth pixel module m4 is in a transmissive mode, the incident light can be reflected on the surface of the data line 9 in addition to entering and exiting from the edge of the second black matrix 5b or the third black matrix 5c. In addition, the first electric field shielding electrode 11a under the data line 9 (as shown in FIG. 7B) and the first electric field shielding electrode 11a parallel to the scan line 10 (as shown in FIG. 7C) can transmit light. In addition, in the projection overlapping area between the data line 9 and the first electric field shielding electrode 11a, the edge distance between the data line 9 and the first electric field shielding electrode 11a is ≥1.5 microns, but the present disclosure is not limited thereto.

[0096] Referring to FIG. 7A, the second black matrix 5b, the pixel electrode 7, the data line 9, and the first electric field shielding electrode 11a are stacked along the z-axis direction z to form a second light passing hole P2, the second light passing hole P2 has a third light passing hole diameter Pa3 along the first radial direction (i.e., the x-axis direction x), and the second light passing hole P2 has a fourth light passing hole diameter Pa4 along the second radial direction (i.e., the y-axis direction y), the third light passing hole diameter Pa3 is determined by a width of the data line 9, and the fourth light passing hole diameter Pa4 is determined by a width of the first electric field shielding electrode 11a or the second black matrix 5b. The third black matrix 5c, the pixel electrode 7, the data line 9, and the first electric field shielding electrode 11a are stacked along the z-axis direction z to form a third light passing hole P3, the third light passing hole P3 has a fifth light passing hole diameter Pa5 along the first radial direction (i.e., the x-axis direction x), and the third light passing hole P3 has a sixth light passing hole diameter Pa6 along the second radial direction (i.e., the y-axis direction y), the fifth light passing hole diameter Pa5 is determined by a width of the data line 9, and the sixth light passing hole diameter Pa6 is determined by a width of the first electric field shielding electrode 11a or the third black matrix 5c. In the first embodiment, the area of the second light passing hole P2 is greater than the area of the first light passing hole P1, and the area of the second light passing hole P2 is equal to the area of the third light passing hole P3, but the present disclosure is not limited thereto.

[0097] In this way, by adjusting the third light passing hole diameter Pa3, the fourth light passing hole diameter Pa4, the fifth light passing hole diameter Pa5, and the sixth light passing hole diameter Pa6, the size of the second light passing hole P2 and the third light passing hole P3 is increased, and the recycling of the incident light is improved, so that a higher aperture ratio can be provided.

[0098] Referring to FIGS. 1, 3B, 8A, 8B, and 8C, FIG. 8A is a schematic diagram illustrating a fifth pixel module of the present disclosure, FIG. 8B is a schematic diagram illustrating a cross-sectional view along line A-A in FIG. 8A, and FIG. 8C is a schematic diagram illustrating a cross-sectional view along line B-B in FIG. 8A. The second display panel G or the third display panel R can include a fifth pixel module m5, the fifth pixel module m5 including the second black matrix 5b or the third black matrix 5c and a reflective second electric field shielding electrode 11b. In the fifth pixel module m5, the second black matrix 5b or the third black matrix 5c shields a portion of the data line 9 (e.g., block S in FIG. 8A) and a portion of the second electric field shielding electrode 11b (e.g., long side L in FIG. 8A) along the z-axis direction z.

[0099] Further explanation, referring to FIG. 8B and FIG. 8C, the arrowed solid line is the path of the incident light, the arrowed dotted line is the path of the reflected light, the arrow of the data line 9 surface represents the metal reflecting light, and the arrow size represents the relative intensity. As can be seen from FIG. 8B and FIG. 8C, because the second electric field shielding electrode 11b of the fifth pixel module m5 is reflective, in addition to the incident light entering and exiting from the edge of the second black matrix 5b or the third black matrix 5c, the incident light can be reflected by the data line 9 without the light shielding part of the second black matrix 5b or the third black matrix 5c, and the part of the second electric field shielding electrode 11b under the data line 9 can also reflect the incident light (as shown in FIG. 8B) to improve the size of the light transmission hole (not shown). At the same time, the part of the second electric field shielding electrode 11b that is partially shielded by the second black matrix 5b or the third black matrix 5c parallel to the scan line 10 can also reflect the incident light (as shown in FIG. 8C). Therefore, compared with the design that the metal line is completely shielded by the aforementioned first black matrix 5a, not only the size of the light transmission hole of the pixel is improved, but also the recycling rate of the reflected incident light is improved, thereby a higher aperture ratio and contrast can be obtained. In addition, in the projection overlap area between the data line 9 and the second electric field shielding electrode 11b, the edge distance of the data line 9 and the second electric field shielding electrode 11b is ≥1.5 microns, but the present disclosure is not limited thereto.

[0100] Referring to FIG. 1, FIG. 3C, FIG. 9A, FIG. 9B and FIG. 9C, wherein FIG. 9A is a schematic diagram showing a sixth pixel module of the present disclosure; FIG. 9B is a schematic diagram showing a cross-sectional view along line A-A in FIG. 9A; and FIG. 9C is a schematic diagram showing a cross-sectional view along line B-B in FIG. 9A. The second display panel G or the third display panel R can further comprise a sixth pixel module m6, the sixth pixel module m6 comprising a second black matrix 5b or a third black matrix 5c and a third electric field shielding electrode 11c which is semi-transmissive and semi-reflective. In the sixth pixel module m6, the second black matrix 5b or the third black matrix 5c shields a part of the data line 9 (as shown in block S of FIG. 9A) and a part of the third electric field shielding electrode 11c (as shown in the long side L of FIG. 9A) along the z-axis direction z.

[0101] Further explanation, referring to FIG. 9B and FIG. 9C, the arrowed solid line is the path of the incident light, the arrowed dotted line is the path of the reflected light, the arrow of the data line 9 surface represents the metal reflecting light, and the arrow size represents the relative intensity. As shown in FIG. 9B and FIG. 9C, because the third electric field shielding electrode 11c of the sixth pixel module m6 is a half-transmission half-reflection type, in addition to the incident light entering and exiting from the edge of the second black matrix 5b or the third black matrix 5c, the incident light can be reflected by the data line 9 without the light shielding part of the second black matrix 5b or the third black matrix 5c, and the part of the third electric field shielding electrode 11c under the data line 9 can also transmit light (as shown in FIG. 9B) to increase the size of the light transmission hole (not labeled separately). At the same time, the part of the third electric field shielding electrode 11c that is partially shielded by the second black matrix 5b or the third black matrix 5c and is parallel to the scan line 10 can also reflect the incident light (as shown in FIG. 9C). Therefore, compared with the design in which the metal line is completely shielded by the first black matrix 5a, not only is the size of the light transmission hole of the pixel increased, but also the recycling rate of the reflected incident light is improved, thereby obtaining a higher aperture ratio and contrast. In addition, in the projection overlap area between the data line 9 and the third electric field shielding electrode 11c, the edge distance between the data line 9 and the third electric field shielding electrode 11c is ≥1.5 microns, but the present disclosure is not limited thereto.

[0102] Referring to FIG. 1 and FIG. 10, wherein FIG. 10 is a schematic diagram showing a display device of a second embodiment of the present disclosure. The display device 200 comprises a plurality of display panels, and each display panel also comprises the upper substrate 1, the protective layer 2, the upper plate common electrode 3, the frame glue 4, a plurality of pixel modules, the lower substrate 12 and the light absorption plate 13 of the display panel of the first embodiment of FIG. 1, and the difference between the display device 200 of the second embodiment and the display device 100 of the first embodiment is that the pixel module of the display device 200 can further comprise an organic layer 14. Specifically, the organic layer 14 is arranged between the pixel electrode 7 and the data line 9, and is connected to the pixel electrode 7.

[0103] It should be particularly pointed out that in the manufacture of the display device 200, the use of the organic layer 14 can reduce the number of masks of the array substrate, thereby reducing the production cost and also reducing the transmission loss of light passing through the organic layer 14.

[0104] Referring to FIG. 1 and FIG. 11, FIG. 11 is a schematic diagram showing a display device of a third embodiment of the present disclosure. The display device 300 comprises a plurality of display panels, each of which comprises the upper substrate 1, the protective layer 2, the upper plate common electrode 3, the frame glue 4, the plurality of pixel modules, the lower substrate 12 and the light absorption plate 13 of the display panel of the second embodiment of FIG. 10. The difference between the display device 300 of the third embodiment and the display device 200 of the aforementioned second embodiment is that the electric field shielding electrode 11 (not labeled separately) of the pixel module of the display device 300 can further comprise a hole h. Specifically, the electric field shielding electrode 11 comprises a first shielding electrode part 113 and a second shielding electrode part 114, and the hole h is formed between the first shielding electrode part 113 and the second shielding electrode part 114. The hole h is located below the data line 9.

[0105] Referring to FIG. 11, FIG. 12A, FIG. 12B, FIG. 12C and FIG. 12D, FIG. 12A is a schematic diagram showing that the hole type electric field shielding electrode and the data line are cut flush; FIG. 12B is a schematic diagram showing that the hole type electric field shielding electrode and the data line are double-sided overlapping; FIG. 12C is a schematic diagram showing that the hole type electric field shielding electrode and the data line are not overlapping; and FIG. 12D is a schematic diagram showing that the hole type electric field shielding electrode and the data line are single-sided overlapping. When the hole type electric field shielding electrode 11 (not labeled separately) is adopted, the projection of the hollowed electric field shielding electrode 11 part and the data line 9 can form various relative projection relationships. As shown in FIG. 12A, the projections of the two ends of the data line 9 are cut flush with the first shielding electrode part 113 and the second shielding electrode part 114, respectively. As shown in FIG. 12B, the projections of the two ends of the data line 9 partially overlap with the first shielding electrode part 113 and the second shielding electrode part 114, respectively. As shown in FIG. 12C, the projections of the two ends of the data line 9 do not overlap with the first shielding electrode part 113 and the second shielding electrode part 114. As shown in FIG. 12D, one end of the projection of the data line 9 partially overlaps with the first shielding electrode part 113.

[0106] It should be particularly pointed out that the hole h of the electric field shielding electrode 11 can reduce the parasitic capacitance between the data line 9 and the electric field shielding electrode 11, thereby reducing the electrostatic shock injury occurring in the preparation process. Through the relative projection relationship between the projection of the part of the electric field shielding electrode 11 and the data line 9, the parasitic capacitance between the data line 9 and the electric field shielding electrode 11 can be adjusted to a different degree, so as to be more suitable for the application of large-size display panels. In addition, the area of the projection of the pixel electrode 7 on the electric field shielding electrode 11 can be used as a storage capacitor.

[0107] It should be particularly pointed out that each of the technical features in the display device of the present disclosure described above can be combined to achieve the corresponding technical effects.

[0108] Referring to FIGS. 1, 4A, 5A, 6A, 7A, 8A, 9A, 10, 11, and 13, wherein FIG. 13 is a tree diagram showing various different electric field shielding electrode category display panel combinations of the present disclosure. First, according to the technical features that the first black matrix 5a completely shields the data lines 9, the scan lines 10, and the electric field shielding electrodes 11 of the first display panel B, while the second black matrix 5b and the third black matrix 5c shield part of the data lines 9 and part of the electric field shielding electrodes 11, and completely shield the scan lines 10, the display devices 100, 200, 300 are all categorized as display device type M, and are represented by code "M" in the first code. Next, the second code represents the category of the electric field shielding electrodes 11 of the first display panel B, the third code represents the category of the electric field shielding electrodes 11 of the second display panel G, and the fourth code represents the category of the electric field shielding electrodes 11 of the third display panel R.

[0109] In detail, according to the category of the electric field shielding electrodes 11 as the coding rule, code "1" represents that the electric field shielding electrodes 11 are of the penetrating type (i.e., the first electric field shielding electrodes 11a), and is represented by the electric field shielding electrode type TR in FIG. 13; code "2" represents that the electric field shielding electrodes 11 are of the reflective type (i.e., the second electric field shielding electrodes 11b), and is represented by the electric field shielding electrode type RE in FIG. 13; and code "3" represents that the electric field shielding electrodes 11 are of the semi-penetrating semi-reflective type (i.e., the third electric field shielding electrodes 11c), and is represented by the electric field shielding electrode type TF in FIG. 13. In this way, the tree diagram of all categories categorized as display device type M can be obtained through the above coding.

[0110] For example, assuming that the display device 100 of category display device type M has the electric field shielding electrodes 11 of the first display panel B of the semi-penetrating semi-reflective type, the electric field shielding electrodes 11 of the second display panel G of the penetrating type, and the electric field shielding electrodes 11 of the third display panel R of the reflective type, this display device 100 can be represented as category "M.3.1.2".

[0111] According to the above embodiments, the following specific examples are proposed and are described in detail with reference to the accompanying drawings.

[0112] Referring to FIGS. 1 to 13, FIG. 14A, FIG. 14B, and FIG. 14C, FIG. 14A is a top view schematic diagram illustrating the first embodiment of the first embodiment of the first embodiment, FIG. 14B is a sectional view schematic diagram illustrating the section along the line A-A in FIG. 14A, and FIG. 14C is a sectional view schematic diagram illustrating the section along the line B-B in FIG. 14A. As illustrated in FIGS. 14A, 14B, and 14C in combination with FIG. 13, the first embodiment of the first embodiment is the display device 100a of the categories M.1.1.1, M.1.1.2, and M.1.1.3. It should be particularly noted that, in the first embodiment of the first embodiment, in order to facilitate comparison of the light paths of the light passing through the aperture and the incident light and the reflected light, the pixel modules of different types of the electric field shielding electrodes 11 (the first electric field shielding electrode 11a, the second electric field shielding electrode 11b, and the third electric field shielding electrode 11c) are juxtaposed in the display panel of the same color; in fact, the same type of the electric field shielding electrode 11 is used in the display panel of the same color.

[0113] In FIG. 14A, the top view schematic diagrams of the first display panel B, the second display panel G, and the third display panel R are separately illustrated from top to bottom. As illustrated in FIG. 14A, the first display panel B of the category M.1.1.1 is the first pixel module m1, the second display panel G and the third display panel R are the fourth pixel module m4, and all of them use the first electric field shielding electrode 11a of the category of the transmissive type; the first display panel B of the category M.1.1.2 is the first pixel module m1, the second display panel G is the fourth pixel module m4, and the third display panel R is the fifth pixel module m5, the first display panel B and the second display panel G use the first electric field shielding electrode 11a of the category of the transmissive type, and the third display panel R uses the second electric field shielding electrode 11b of the category of the reflective type; the first display panel B of the category M.1.1.3 is the first pixel module m1, the second display panel G is the fourth pixel module m4, and the third display panel R is the sixth pixel module m6, the first display panel B and the second display panel G use the first electric field shielding electrode 11a of the category of the transmissive type, and the third display panel R uses the third electric field shielding electrode 11c of the category of the semi-transmissive and semi-reflective type.

[0114] In FIG. 14B, from top to bottom are cross-sectional views of the first display panel B, the second display panel G, and the third display panel R at the position of the data line 9. As shown in FIG. 14B, the three types of electric field shielding electrodes 11 (the first electric field shielding electrode 11a, the second electric field shielding electrode 11b, and the third electric field shielding electrode 11c) are all located below the data line 9. The first electric field shielding electrodes 11a of the first display panel B and the second display panel G, the first electric field shielding electrodes 11a and the third electric field shielding electrodes 11c of the third display panel R of the M.1.1.1, M.1.1.3 types are all light-transmissive, while the second electric field shielding electrodes 11b of the third display panel R of the M.1.1.2 type are metal layers that are not light-transmissive.

[0115] Further, the solid arrows represent the paths of the incident light, the dashed arrows represent the paths of the reflected light, the arrows on the surface of the data line 9 represent the reflection of the light by the metal, and the sizes of the arrows represent the relative intensities. The light-transmissive holes (not labeled) of the first display panel B of the three types are limited by the widths of the first black matrix 5a. Except for the light-transmissive holes of the third display panel R of the M.1.1.2 type, which are determined by the widths of the second electric field shielding electrodes 11b, the sizes of the light-transmissive holes are all determined by the widths of the data line 9. In the first embodiment of the first embodiment, the widths of the first electric field shielding electrodes 11a, the second electric field shielding electrodes 11b, and the third electric field shielding electrodes 11c are all greater than the width of the data line 9.

[0116] The metal lines of the three types that are not shielded by the first black matrix 5a can all reflect the incident light, thereby improving the recycling rate of the incident light. Among the three types, the third display panel R has the following relationship in terms of the intensity of the reflected light: M.1.1.2 > M.1.1.1 = M.1.1.3, and the following relationship in terms of the size of the light-transmissive hole: M.1.1.1 = M.1.1.3 > M.1.1.2.

[0117] In FIG. 14C, from top to bottom are cross-sectional views of the first display panel B, the second display panel G, and the third display panel R at the position of the scan line 10. As shown in FIG. 14C, the first electric field shielding electrodes 11a of the first display panel B and the second display panel G of the three types are all light-transmissive, the first electric field shielding electrodes 11a of the third display panel R of the M.1.1.1 type are also light-transmissive, while the second electric field shielding electrodes 11b and the third electric field shielding electrodes 11c of the third display panel R of the M.1.1.2 and M.1.1.3 types are metal layers that are not light-transmissive.

[0118] Further explanation, the solid line with arrow is the path of incident light, dotted line with arrow is the path of reflected light, the arrow on the surface of data line 9 indicates that the metal reflects light, and the arrow size indicates the relative intensity. The light transmission hole (not labeled separately) of the first display panel B of the three categories of M.1.1.1, M.1.1.2 and M.1.1.3 is limited by the width of the first black matrix 5a. Except that the size of the light transmission hole of the third display panel R of the two categories of M.1.1.2 and M.1.1.3 is determined by the width of the second electric field shielding electrode 11b and the third electric field shielding electrode 11c, the others are determined by the width of the second black matrix 5b and the third black matrix 5c. The metal lines not shielded by the first black matrix 5a, the second black matrix 5b and the third black matrix 5c can reflect the incident light and thereby improve the recycling rate of the incident light; among the three categories, the intensity of the reflected light of the third display panel R is: M.1.1.2 = M.1.1.3 > M.1.1.1; the size relationship of the light transmission hole is: M.1.1.1 > M.1.1.2 = M.1.1.3.

[0119] In this way, in addition to minimizing the width of the first black matrix 5a, the second black matrix 5b and the third black matrix 5c, only partially shielding the data line 9 and the second electric field shielding electrode 11b and the third electric field shielding electrode 11c can improve the size of the light transmission hole and the recycling rate of the incident light to different degrees, and when the first display panel B, the second display panel G and the third display panel R are aligned, the degree of influence of the width of the first black matrix 5a, the second black matrix 5b and the third black matrix 5c is greatly reduced, thereby greatly improving the aperture ratio and contrast of the display device 100a.

[0120] Referring to FIGS. 1 to 13, FIGS. 15A, 15B and 15C, FIG. 15A is a top view of a first embodiment of the second embodiment of the display device 200a according to FIG. 10, FIG. 15B is a sectional view of FIG. 15A along the line A-A, and FIG. 15C is a sectional view of FIG. 15A along the line B-B. As shown in FIGS. 15A, 15B and 15C in combination with FIG. 13, the first embodiment of the second embodiment is the display device 200a of the categories M.1.1.1, M.1.1.2 and M.1.1.3. The display device 200a of the first embodiment of the second embodiment is different from the display device 100a of the first embodiment of the first embodiment in that the plurality of pixel modules of the display device 200a further include the organic layer 14. It should be noted that in the first embodiment of the second embodiment, in order to facilitate comparison of the light paths of the light passing through the aperture and the incident light and the reflected light, the pixel modules of different types of the electric field shielding electrode 11 (the first electric field shielding electrode 11a, the second electric field shielding electrode 11b and the third electric field shielding electrode 11c) are juxtaposed in the display panel of the same color; in fact, the same type of electric field shielding electrode 11 is used in the display panel of the same color.

[0121] In FIG. 15A, the top views of the first display panel B, the second display panel G and the third display panel R are shown separately from top to bottom. In the first embodiment of the second embodiment, the types of the pixel modules provided in the first display panel B, the second display panel G and the third display panel R are the same as those of the first display panel B, the second display panel G and the third display panel R of FIG. 14A, respectively, and thus no further description is given herein.

[0122] In FIG. 15B, the sectional views of the first display panel B, the second display panel G and the third display panel R at the positions of the data lines 9 are shown separately from top to bottom. In FIG. 15C, the sectional views of the first display panel B, the second display panel G and the third display panel R at the positions of the scan lines 10 are shown separately from top to bottom. In the first embodiment of the second embodiment, the paths of the incident light, the paths of the reflected light, the metal reflection of the surfaces of the data lines 9 and the relative intensities thereof of the three categories M.1.1.1, M.1.1.2 and M.1.1.3 are the same as those of FIGS. 14B and 14C, respectively, and thus no further description is given herein.

[0123] Therefore, in addition to minimizing the width of the first black matrix 5a, the second black matrix 5b, and the third black matrix 5c, only the partial shielding of the data line 9 and the second electric field shielding electrode 11b and the third electric field shielding electrode 11c can improve the size of the light aperture and the recycling rate of the incident light to different degrees. When the first display panel B, the second display panel G, and the third display panel R are aligned, the degree of influence of the width of the first black matrix 5a, the second black matrix 5b, and the third black matrix 5c is greatly reduced, thereby greatly improving the aperture ratio and contrast of the display device 200a.

[0124] In addition, the number of masks of the array substrate can be reduced by the organic layer 14, which can reduce the production cost and reduce the transmission loss of light passing through the organic layer 14.

[0125] Referring to FIGS. 1 to 13, 16A, and 16B, wherein FIG. 16A is a top view schematic diagram of the first embodiment of the third embodiment according to FIG. 11; and FIG. 16B is a cross-sectional view schematic diagram along line A-A in FIG. 16A. As shown in FIGS. 16A and 16B in combination with the classification in FIG. 13, the first embodiment of the third embodiment is a display device 300a of the M.1.1.1, M.1.1.2, and M.1.1.3 categories. The difference between the display device 300a of the first embodiment of the third embodiment and the display device 200a of the first embodiment of the second embodiment is that the first electric field shielding electrode 11a, the second electric field shielding electrode 11b, and the third electric field shielding electrode 11c of the plurality of pixel modules of the display device 300a further include a hole h. It should be particularly noted that in the first embodiment of the third embodiment, in order to facilitate the comparison of the light aperture and the light paths of the incident light and the reflected light, the pixel modules of different electric field shielding electrodes 11 (the first electric field shielding electrode 11a, the second electric field shielding electrode 11b, and the third electric field shielding electrode 11c) are arranged side by side in the display panel of the same color; in fact, the same color display panel uses the same type of electric field shielding electrode 11.

[0126] In FIG. 16A, the top view schematic diagrams of the first display panel B, the second display panel G, and the third display panel R are separately shown from top to bottom. In the first embodiment of the third embodiment, the types of the pixel modules provided by the first display panel B, the second display panel G, and the third display panel R are the same as those of the first display panel B, the second display panel G, and the third display panel R in FIG. 14A, and will not be described again here.

[0127] In FIG. 16B, from top to bottom are cross-sectional views of the first display panel B, the second display panel G, and the third display panel R at the position of the data line 9. In the first embodiment of the third implementation, the paths of the incident light, the reflected light, and the metal-reflected light of the data line 9 surface and their relative intensities of the three types of incident light M.1.1.1, M.1.1.2, and M.1.1.3 are the same as those of FIG. 14B, and thus are not described again.

[0128] In this way, in addition to minimizing the shielding widths of the first black matrix 5a, the second black matrix 5b, and the third black matrix 5c, the partial shielding of the data line 9 and the second field shielding electrode 11b and the third field shielding electrode 11c can improve the light hole size and the recycling rate of the incident light to different degrees. When the first display panel B, the second display panel G, and the third display panel R are aligned, the degree of influence of the widths of the first black matrix 5a, the second black matrix 5b, and the third black matrix 5c is greatly reduced, thereby greatly improving the aperture ratio and the contrast of the display device 300a.

[0129] In addition, the holes h of the first field shielding electrode 11a, the second field shielding electrode 11b, and the third field shielding electrode 11c can reduce the parasitic capacitance of the data line 9 and the first field shielding electrode 11a, the second field shielding electrode 11b, and the third field shielding electrode 11c, and reduce the electrostatic shock injury that occurs during the preparation process.

[0130] Referring to FIGS. 1 to 13, 17A, 17B, and 17C, wherein FIG. 17A is a top view, FIG. 17B is a cross-sectional view along line A-A of FIG. 17A, and FIG. 17C is a cross-sectional view along line B-B of FIG. 17A. As shown in FIGS. 17A, 17B, and 17C in combination with the classification description of FIG. 13, the second embodiment of the first implementation is the display device 100b including the M.2.3.1, M.2.3.2, and M.2.3.3 types. It should be particularly noted that, in the second embodiment of the first implementation, in order to facilitate the comparison of the light hole and the light paths of the incident light and the reflected light, the pixel modules of different types of field shielding electrodes 11 (the first field shielding electrode 11a, the second field shielding electrode 11b, and the third field shielding electrode 11c) are arranged side by side in the display panel of the same color; in fact, the same type of field shielding electrode 11 is used in the display panel of the same color.

[0131] In FIG. 17A, the top view schematic diagrams of the first display panel B, the second display panel G and the third display panel R are separately shown from top to bottom.

[0132] In FIG. 17B, the cross-sectional schematic diagrams of the first display panel B, the second display panel G and the third display panel R at the position of the data line 9 are separately shown from top to bottom. As shown in FIG. 17B, the electric field shielding electrodes 11 (the first electric field shielding electrode 11a, the second electric field shielding electrode 11b and the third electric field shielding electrode 11c) of the M.2.3.1, M.2.3.2 and M.2.3.3 categories are all located below the data line 9, and the second electric field shielding electrodes 11b of the first display panel B of the three categories are all metal layers that are not transparent to light, the third electric field shielding electrodes 11c of the second display panel G are all transparent, the first electric field shielding electrodes 11a and the third electric field shielding electrodes 11c of the third display panel R of the M.2.3.1 and M.2.3.3 categories are both transparent, and the second electric field shielding electrodes 11b of the third display panel R of the M.2.3.2 category are metal layers that are not transparent to light.

[0133] Further, the solid arrowed line is the path of the incident light, the dotted arrowed line is the path of the reflected light, the arrow on the data line 9 surface indicates the metal reflects the light, and the arrow size indicates the relative intensity. The light transmission hole (not labeled) of the first display panel B of the three categories M.2.3.1, M.2.3.2 and M.2.3.3 is limited by the width of the first black matrix 5a. The light transmission hole size of the second display panel G of the three categories M.2.3.1, M.2.3.2 and M.2.3.3 and the third display panel R of the categories M.2.3.1 and M.2.3.3 is determined by the width of the data line 9, and the light transmission hole size of the category M.2.3.2 is determined by the width of the second field shielding electrode 11b. In the second embodiment of the first embodiment, the widths of the first field shielding electrode 11a, the second field shielding electrode 11b and the third field shielding electrode 11c are greater than the width of the data line 9.

[0134] The metal lines of the three categories M.2.3.1, M.2.3.2 and M.2.3.3 that are not shielded by the first black matrix 5a can reflect the incident light and improve the recycling rate of the incident light. In the three categories, the intensity of the reflected light of the third display panel R is in the order of M.2.3.2 > M.2.3.1 = M.2.3.3, and the size of the light transmission hole is in the order of M.2.3.1 = M.2.3.3 > M.2.3.2.

[0135] In FIG. 17C, from top to bottom are the cross-sectional schematic views of the first display panel B, the second display panel G and the third display panel R at the position of the scanning line 10. As shown in FIG. 17C, except that the first field shielding electrode 11a of the third display panel R of the category M.2.3.1 is light-transmissive, the other second field shielding electrode 11b and third field shielding electrode 11c are metal layers that are not light-transmissive.

[0136] Further, the solid arrowed line is the path of the incident light, the dotted arrowed line is the path of the reflected light, the arrow on the surface of the data line 9 indicates that the metal reflects light, and the arrow size indicates the relative intensity. The light transmission holes (not labeled) of the three types of first display panel B are limited by the width of the first black matrix 5a. Except for the third display panel R of the M.2.3.1 type, the size of the light transmission hole is determined by the width of the third black matrix 5c. The width of the first electric field shielding electrode 11a, the second electric field shielding electrode 11b, and the third electric field shielding electrode 11c. The metal lines not shielded by the first black matrix 5a, the second black matrix 5b, and the third black matrix 5c can reflect the incident light and improve the recycling rate of the incident light; among the three types, the reflected light intensity of the third display panel R is: M.2.3.2 = M.2.3.3 > M.2.3.1; the size relationship of the light transmission hole is: M.2.3.1 > M.2.3.2 = M.2.3.3.

[0137] In this way, in addition to minimizing the width of the first black matrix 5a, the second black matrix 5b, and the third black matrix 5c, only partially shielding the data line 9 and the second electric field shielding electrode 11b and the third electric field shielding electrode 11c can improve the size of the light transmission hole and the recycling rate of the incident light to varying degrees. When the first display panel B, the second display panel G, and the third display panel R are aligned, the degree of influence of the width of the first black matrix 5a, the second black matrix 5b, and the third black matrix 5c is greatly reduced, thereby greatly improving the aperture ratio and contrast of the display device 100b.

[0138] Referring to FIGS. 1 to 13, FIG. 18A, FIG. 18B, and FIG. 18C, wherein FIG. 18A is a top view schematic diagram showing a second embodiment of the second embodiment according to the second embodiment of FIG. 10; FIG. 18B is a cross-sectional view schematic diagram showing the line A-A of FIG. 18A; and FIG. 18C is a cross-sectional view schematic diagram showing the line B-B of FIG. 18A. As shown in FIGS. 18A, 18B, and 18C in combination with FIG. 13, the second embodiment of the second embodiment is a display device 200b belonging to the categories of M.2.3.1, M.2.3.2, and M.2.3.3. The difference between the display device 200b of the second embodiment of the second embodiment and the display device 100b of the second embodiment of the first embodiment is that the plurality of pixel modules of the display device 200b further comprises an organic layer 14. It should be noted that in the second embodiment of the second embodiment, in order to facilitate comparison of the light paths of the light passing through the aperture and the incident light and the reflected light, the pixel modules of different types of electric field shielding electrodes 11 (the first electric field shielding electrode 11a, the second electric field shielding electrode 11b, and the third electric field shielding electrode 11c) are juxtaposed in the display panel of the same color; in fact, the same type of electric field shielding electrode 11 is used in the display panel of the same color.

[0139] In FIG. 18A, the top view schematic diagrams of the first display panel B, the second display panel G, and the third display panel R are shown separately from top to bottom. In the second embodiment of the second embodiment, the types of pixel modules provided by the first display panel B, the second display panel G, and the third display panel R are the same as those of the first display panel B, the second display panel G, and the third display panel R of FIG. 17A, respectively, and will not be described again.

[0140] In FIG. 18B, from top to bottom are the cross-sectional view schematic diagrams of the first display panel B, the second display panel G, and the third display panel R at the position of the data line 9. In FIG. 18C, from top to bottom are the cross-sectional view schematic diagrams of the first display panel B, the second display panel G, and the third display panel R at the position of the scan line 10. In the second embodiment of the second embodiment, the paths of the incident light, the paths of the reflected light, and the metal reflection of the surface of the data line 9 and their relative intensities of the three categories of M.2.3.1, M.2.3.2, and M.2.3.3 are the same as those of FIGS. 17B and 17C, respectively, and will not be described again.

[0141] Therefore, in addition to minimizing the width of the first black matrix 5a, the second black matrix 5b, and the third black matrix 5c, only the partial shielding of the data line 9 and the second electric field shielding electrode 11b and the third electric field shielding electrode 11c can improve the size of the light aperture and the recycling rate of the incident light to different degrees. When the first display panel B, the second display panel G, and the third display panel R are aligned, the degree of influence of the width of the first black matrix 5a, the second black matrix 5b, and the third black matrix 5c is greatly reduced, thereby greatly improving the aperture ratio and contrast of the display device 200b.

[0142] In addition, the number of masks of the array substrate can be reduced by the organic layer 14, which can reduce the production cost and reduce the transmission loss of light passing through the organic layer 14.

[0143] Referring to FIGS. 1 to 13, 19A, and 19B, wherein FIG. 19A is a top view schematic diagram of the second embodiment of the third embodiment according to FIG. 11, and FIG. 19B is a sectional view schematic diagram along the line A-A in FIG. 19A. As shown in FIGS. 19A and 19B in combination with the classification in FIG. 13, the second embodiment of the third embodiment is the display device 300b of the M.2.3.1, M.2.3.2, and M.2.3.3 categories. The difference between the display device 300b of the second embodiment of the third embodiment and the display device 200b of the second embodiment of the second embodiment is that the first electric field shielding electrode 11a, the second electric field shielding electrode 11b, and the third electric field shielding electrode 11c of the plurality of pixel modules of the display device 300b further include a hole h. It should be particularly pointed out that in the second embodiment of the third embodiment, in order to facilitate the comparison of the light aperture and the light paths of the incident light and the reflected light, the pixel modules of different electric field shielding electrodes 11 (the first electric field shielding electrode 11a, the second electric field shielding electrode 11b, and the third electric field shielding electrode 11c) are arranged side by side in the display panel of the same color; in fact, the same color display panel uses the same type of electric field shielding electrode 11.

[0144] In FIG. 19A, the top view schematic diagrams of the first display panel B, the second display panel G, and the third display panel R are separately shown from top to bottom. In the second embodiment of the third embodiment, the types of the pixel modules provided by the first display panel B, the second display panel G, and the third display panel R are the same as those of the first display panel B, the second display panel G, and the third display panel R in FIG. 17A, which will not be described again.

In the second embodiment of the third embodiment of the first embodiment, the paths of the incident light, the reflected light, and the metal-reflected light from the surface of the data line 9, and the relative intensity of the metal-reflected light of the three types of incident light, M.2.3.1, M.2.3.2, and M.2.3.3, are the same as the paths of the incident light, the reflected light, and the metal-reflected light from the surface of the data line 9, and the relative intensity of the metal-reflected light of FIG. 17B, and are not described again here.

[0146] In this way, in addition to minimizing the shielding width of the first black matrix 5a, the second black matrix 5b, and the third black matrix 5c, partially shielding the data line 9 and the second electric field shielding electrode 11b and the third electric field shielding electrode 11c can improve the size of the light passing hole and the recycling rate of the incident light to different degrees. When the first display panel B, the second display panel G, and the third display panel R are aligned, the degree of influence of the width of the first black matrix 5a, the second black matrix 5b, and the third black matrix 5c is greatly reduced, thereby greatly improving the aperture ratio and the contrast of the display device 300b.

[0147] In addition, the holes h of the first electric field shielding electrode 11a, the second electric field shielding electrode 11b, and the third electric field shielding electrode 11c can reduce the parasitic capacitance of the data line 9 and the first electric field shielding electrode 11a, the second electric field shielding electrode 11b, and the third electric field shielding electrode 11c, and reduce the electrostatic shock that occurs during the preparation process.

[0148] Referring to FIGS. 1 to 13, 20A, 20B, and 20C, wherein FIG. 20A is a top view schematic diagram of the third embodiment according to the first embodiment of FIG. 1; FIG. 20B is a cross-sectional schematic view along the line A-A in FIG. 20A; and FIG. 20C is a cross-sectional schematic view along the line B-B in FIG. 20A. As can be seen from the classification description of FIGS. 20A, 20B, and 20C in conjunction with FIG. 13, the third embodiment of the first embodiment is the display device 100c including the M.3.2.1, M.3.2.2, and M.3.2.3 categories. It should be particularly pointed out that, in the third embodiment of the first embodiment, in order to facilitate the comparison of the light passing hole and the light paths of the incident light and the reflected light, the pixel modules of different types of electric field shielding electrodes 11 (the first electric field shielding electrode 11a, the second electric field shielding electrode 11b, and the third electric field shielding electrode 11c) are juxtaposed in the display panel of the same color; in fact, the same color display panel is all using the same type of electric field shielding electrode 11.

[0149] In FIG. 20A, the top view schematic diagrams of the first display panel B, the second display panel G and the third display panel R are shown separately from top to bottom.

[0150] In FIG. 20B, the cross-sectional schematic diagrams of the first display panel B, the second display panel G and the third display panel R at the position of the data line 9 are shown from top to bottom. As shown in FIG. 20B, the first electric field shielding electrode 11a and the third electric field shielding electrode 11c of the third display panel R of the M.3.2.1, M.3.2.2 and M.3.2.3 categories are all located below the data line 9, the third electric field shielding electrode 11c of the first display panel B of the three categories is a light-transmissive layer, the second electric field shielding electrode 11b of the second display panel G is a metal layer, and the first electric field shielding electrode 11a and the third electric field shielding electrode 11c of the third display panel R of the M.3.2.1 and M.3.2.3 categories are light-transmissive.

[0151] Further, the solid arrowed line is the path of the incident light, the dashed arrowed line is the path of the reflected light, the arrow on the surface of the data line 9 indicates the reflection of the metal, and the arrow size represents the relative intensity. The first display panel B of the M.3.2.1, M.3.2.2 and M.3.2.3 categories (not labeled) is limited by the width of the first black matrix 5a. Except that the light-transmissive hole size of the third display panel R of the M.3.2.1 and M.3.2.3 categories is determined by the width of the data line 9, the light-transmissive hole size of the other is determined by the width of the second electric field shielding electrode 11b and the third electric field shielding electrode 11c.

[0152] The metal lines in the three categories M.3.2.1, M.3.2.2 and M.3.2.3 that are not shielded by the first black matrix 5a can reflect the incident light and thereby improve the recycling rate of the incident light; among the three categories, the intensity of the reflected light of the third display panel R is in the order of M.3.2.2 > M.3.2.1 = M.3.2.3; the size of the light transmission hole is in the order of M.3.2.1 = M.3.2.3 > M.3.2.2.

[0153] In FIG. 20C, from top to bottom are the cross-sectional schematic diagrams of the first display panel B, the second display panel G and the third display panel R at the position of the scanning line 10. As can be seen from FIG. 20C, except that the first electric field shielding electrode 11a of the third display panel R in the category M.3.2.1 is light-transmissive, the other second electric field shielding electrodes 11b and third electric field shielding electrodes 11c are all metal layers that are not light-transmissive.

[0154] Further explanation, the solid line with arrow is the path of the incident light, the dotted line with arrow is the path of the reflected light, the arrow on the surface of the data line 9 indicates that the metal reflects light, and the arrow size indicates the relative intensity. The light transmission hole (not labeled separately) of the first display panel B in the three categories M.3.2.1, M.3.2.2 and M.3.2.3 is limited by the width of the first black matrix 5a. Except that the size of the light transmission hole of the third display panel R in the category M.3.2.1 is determined by the width of the third black matrix 5c, the other is determined by the width of the second electric field shielding electrode 11b and the third electric field shielding electrode 11c. The metal lines that are not shielded by the first black matrix 5a, the second black matrix 5b and the third black matrix 5c can reflect the incident light and thereby improve the recycling rate of the incident light; among the three categories, the intensity of the reflected light of the third display panel R is in the order of M.3.2.2 = M.3.2.3 > M.3.2.1; the size of the light transmission hole is in the order of M.3.2.1 > M.3.2.2 = M.3.2.3.

[0155] In this way, in addition to minimizing the width of the first black matrix 5a, the second black matrix 5b and the third black matrix 5c, only partially shielding the data line 9 and the second electric field shielding electrode 11b and the third electric field shielding electrode 11c can improve the size of the light transmission hole and the recycling rate of the incident light to different degrees. When the first display panel B, the second display panel G and the third display panel R are aligned, the degree of influence of the width of the first black matrix 5a, the second black matrix 5b and the third black matrix 5c is greatly reduced, thereby greatly improving the aperture ratio and contrast of the display device 100c.

As shown in FIGS. 21A, 21B and 21C in combination with FIG. 13, the third embodiment of the second embodiment is a display device 200c belonging to the categories of M.3.2.1, M.3.2.2 and M.3.2.3. The display device 200c of the third embodiment of the second embodiment differs from the display device 100c of the third embodiment of the first embodiment in that the pixel module of the display device 200c further includes an organic layer 14. It should be noted that in the third embodiment of the second embodiment, in order to facilitate comparison of the light paths of the light passing through the aperture and the incident light and the reflected light, the pixel modules of different types of electric field shielding electrodes 11 (the first electric field shielding electrode 11a, the second electric field shielding electrode 11b and the third electric field shielding electrode 11c) are juxtaposed in the display panel of the same color; in fact, the same type of electric field shielding electrode 11 is used in the display panel of the same color.

[0157] In FIG. 21A, the top views of the first display panel B, the second display panel G and the third display panel R are shown separately from top to bottom. In the third embodiment of the second embodiment, the types of the pixel modules provided in the first display panel B, the second display panel G and the third display panel R are the same as those of the first display panel B, the second display panel G and the third display panel R of FIG. 20A, respectively, and thus no further description is given herein.

[0158] In FIG. 21B, the sectional views of the first display panel B, the second display panel G and the third display panel R at the positions of the data lines 9 are shown separately from top to bottom. In FIG. 21C, the sectional views of the first display panel B, the second display panel G and the third display panel R at the positions of the scan lines 10 are shown separately from top to bottom. In the third embodiment of the second embodiment, the paths of the incident light, the paths of the reflected light, the metal reflection of the surfaces of the data lines 9 and their relative intensities of the three categories of M.3.2.1, M.3.2.2 and M.3.2.3 are the same as those of FIGS. 20B and 20C, respectively, and thus no further description is given herein.

[0159] Therefore, in addition to minimizing the width of the first black matrix 5a, the second black matrix 5b, and the third black matrix 5c, only the partial shielding of the data line 9 and the second electric field shielding electrode 11b and the third electric field shielding electrode 11c can improve the size of the light aperture and the recycling rate of the incident light to different degrees. When the first display panel B, the second display panel G, and the third display panel R are aligned, the degree of influence of the width of the first black matrix 5a, the second black matrix 5b, and the third black matrix 5c is greatly reduced, thereby greatly improving the aperture ratio and contrast of the display device 200c.

[0160] In addition, the number of masks of the array substrate can be reduced by the organic layer 14, which can reduce the production cost and reduce the transmission loss of light passing through the organic layer 14.

[0161] Referring to FIGS. 1 to 13, 22A, and 22B, wherein FIG. 22A is a top view schematic diagram of the third embodiment according to the third embodiment of the third embodiment of FIG. 11; and FIG. 22B is a cross-sectional view schematic diagram along the line A-A in FIG. 22A. As shown in FIGS. 22A and 22B in combination with the classification of FIG. 13, the third embodiment of the third embodiment of the third embodiment is a display device 300c including the M.3.2.1, M.3.2.2, and M.3.2.3 categories. The display device 300c of the third embodiment of the third embodiment is different from the display device 200c of the third embodiment of the second embodiment in that the first electric field shielding electrode 11a, the second electric field shielding electrode 11b, and the third electric field shielding electrode 11c of the plurality of pixel modules of the display device 300c further include a hole h. It should be particularly noted that in the third embodiment of the third embodiment, in order to facilitate comparison of the light aperture and the light paths of the incident light and the reflected light, the pixel modules of different electric field shielding electrodes 11 (the first electric field shielding electrode 11a, the second electric field shielding electrode 11b, and the third electric field shielding electrode 11c) are arranged side by side in the display panel of the same color; in fact, the same color display panel uses the same type of electric field shielding electrode 11.

[0162] In FIG. 22A, the top view schematic diagrams of the first display panel B, the second display panel G, and the third display panel R are separately shown from top to bottom. In the second embodiment of the third embodiment, the types of pixel modules provided by the first display panel B, the second display panel G, and the third display panel R are the same as those of the first display panel B, the second display panel G, and the third display panel R of FIG. 20A, and will not be described again here.

[0163] In FIG. 22B, from top to bottom are respectively the cross-sectional schematic diagrams of the first display panel B, the second display panel G and the third display panel R at the position of the data line 9. In the third embodiment of the third embodiment, the paths of the three types of incident light M.3.2.1, M.3.2.2 and M.3.2.3, the paths of the reflected light, the metal reflection of the data line 9 surface and their relative intensity are the same as those of FIG. 20B, and will not be described again here.

[0164] In this way, in addition to minimizing the shielding width of the first black matrix 5a, the second black matrix 5b and the third black matrix 5c, only partially shielding the data line 9 and the second electric field shielding electrode 11b and the third electric field shielding electrode 11c can improve the light hole size and the recycling rate of the incident light to different degrees, and when the first display panel B, the second display panel G and the third display panel R are aligned, the degree of influence of the width of the first black matrix 5a, the second black matrix 5b and the third black matrix 5c is greatly reduced, thereby greatly improving the aperture ratio and contrast of the display device 300c.

[0165] In addition, the holes h of the first electric field shielding electrode 11a, the second electric field shielding electrode 11b and the third electric field shielding electrode 11c can reduce the parasitic capacitance of the data line 9 and the first electric field shielding electrode 11a, the second electric field shielding electrode 11b and the third electric field shielding electrode 11c, and reduce the static electricity injury that occurs during the preparation process.

[0166] As can be seen from the above embodiments, the present disclosure has the following advantages: by adjusting the light hole diameter to improve the light hole size and the recycling rate of the reflected incident light, a display device with higher aperture ratio and contrast can be provided. In addition, the first display panel, the second display panel and the third display panel with different optical reflection and transmission characteristics are variously combined, which not only can greatly reduce the aperture ratio loss caused by the large shielding width of the black matrix or the insufficient alignment accuracy during the display panel alignment process, but also can obtain various full-color active cholesteric liquid crystal display devices with different degrees of improvement in aperture ratio and contrast.

[0167] Although the present disclosure has been disclosed as above with embodiments, it is not intended to limit the present disclosure, and any person skilled in the art can make some changes and modifications without departing from the concept and scope of the present disclosure, and therefore the protection scope of the present disclosure shall be subject to the definition of the claims.
