Description

Technical Field

[0001] The present invention relates to a display panel, and in particular to a display panel provided with spacers. Background Art

[0002] Generally speaking, to form a cavity filled with liquid crystal material, most LCD panels use spacers to separate the upper and lower substrates by a specific distance. In reflective LCD panels, given the high flatness of the film layer on the substrate that supports the spacers, one current approach is to place the spacers above the color filter pattern. However, this design significantly affects the transmittance of the color filter pattern, resulting in poor color performance in the reflective LCD panel, such as color shift or a reduced color gamut. Summary of the Invention

[0003] The present invention is directed to a display panel, wherein the arrangement of spacers has a relatively slight effect on display colors.

[0004] According to an embodiment of the present invention, a display panel includes a first substrate, a second substrate, a plurality of pixel structures, a plurality of color filter patterns, a plurality of spacers, and a liquid crystal layer. The first substrate and the second substrate are arranged to overlap each other. A plurality of pixel structures are arranged on the first substrate, and each includes a reflective electrode. A plurality of color filter patterns overlap the plurality of reflective electrodes of the pixel structures, respectively. A plurality of spacers are arranged between the first substrate and the second substrate. A liquid crystal layer is arranged between the first substrate and the second substrate. The pixel structures include a first pixel structure, the spacers include a first spacer, and the color filter patterns include a first color filter pattern. The reflective electrode of the first pixel structure overlaps the first spacer and the first color filter pattern, and at least a portion of the first spacer does not overlap the first color filter pattern.

[0005] In an embodiment according to the present invention, the display panel further includes a plurality of light-transmitting patterns.

These light-transmitting patterns include a first light-transmitting pattern, the reflective electrode of the first pixel structure overlaps the first light-transmitting pattern, and the first spacer overlaps the first light-transmitting pattern.

[0006] In the display panel according to the embodiment of the present invention, an orthographic projection of the first spacer on the substrate surface of the second substrate is located within an orthographic projection of the reflective electrode of the first pixel structure on the substrate surface of the second substrate.

[0008] In an embodiment according to the present invention, the display panel further includes a first alignment layer and a second alignment layer, disposed on the first substrate and the second substrate, respectively, and sandwiching a liquid crystal layer. The first alignment layer has a first alignment direction, and the second alignment layer has a second alignment direction. The orthographic projection of the first spacer on the substrate surface of the second substrate is an elongated strip, and the extension direction of the first spacer is parallel to the first alignment direction or the second alignment direction.

[0010] In the display panel according to the embodiment of the present invention, an orthographic projection area of the first spacer on the substrate surface is different from an orthographic projection area of the second spacer on the substrate surface.

[0011] In the display panel according to the embodiment of the present invention, the first spacer has a first height along the normal direction of the substrate surface, the second spacer has a second height along the normal direction of the substrate surface, and the first height is different from the second height.

[0012] In a display panel according to an embodiment of the present invention, the pixel structures further include a second pixel structure, and the second pixel structure is adjacent to the first pixel structure. The color filter patterns further include a second color filter pattern. The reflective electrode of the second pixel structure overlaps the second color filter pattern. The orthographic projection of the first spacer on the substrate surface of the second substrate is in the shape of an elongated strip or a dot, and the first spacer partially overlaps the region between the reflective electrode of the first pixel structure and the reflective electrode of the second pixel structure.

[0013] In an embodiment according to the present invention, the display panel further includes a first alignment layer and a second alignment layer, disposed on the first substrate and the second substrate, respectively, and sandwiching a liquid crystal layer. The first alignment layer has a first alignment direction, and the second alignment layer has a second alignment direction. The orthographic projection of the first spacer on the substrate surface of the second substrate is in the shape of an elongated strip. The extension direction of the first spacer is parallel to the first alignment direction or the second alignment direction, and the width of the end of the first spacer gradually decreases toward the first alignment direction or the second alignment direction.

[0014] In an embodiment according to the present invention, the display panel further comprises a first alignment layer and a second alignment layer, which are respectively arranged on the first substrate and the second substrate, and sandwiched with a liquid crystal layer. The first alignment layer has a first alignment direction, and the second alignment layer has a second alignment direction. These pixel structures further comprise a second pixel structure, and the second pixel structure is adjacent to the first pixel structure. These color filter patterns further comprise a second color filter pattern, and the reflective electrode of the second pixel structure overlaps the second color filter pattern. The orthographic projection outline of the first spacer on the substrate surface of the second substrate is a rhombus, and the extension direction of the virtual connection line of the two relative corners of the four corners of the rhombus is parallel to the first alignment direction or the second alignment direction, and the first spacer partially overlaps the area between the reflective electrode of the first pixel structure and the reflective electrode of the second pixel structure.

[0015] In the display panel according to the embodiment of the present invention, a first portion of the reflective electrode of the first pixel structure overlaps the first color filter pattern but does not overlap the first spacer, and a second portion of the reflective electrode of the first pixel structure overlaps the first spacer but does not overlap the first color filter pattern.

[0016] In an embodiment according to the present invention, the display panel further includes a plurality of light-transmitting patterns that respectively overlap the plurality of reflective electrodes of the pixel structures. The light-transmitting patterns include a first light-transmitting pattern. A first portion and a second portion of the reflective electrode of the first pixel structure do not overlap the first light-transmitting pattern, and a third portion of the reflective electrode of the first pixel structure overlaps the first light-transmitting pattern but does not overlap the first color filter pattern and the first spacer.

[0017] In a display panel according to an embodiment of the present invention, the first pixel structure further includes an insulating layer and an active device. The spacers further include a second spacer. The active device is disposed on the first substrate, and the insulating layer is disposed over the active device and has an opening that overlaps with the reflective electrode of the first pixel structure. The reflective electrode of the first pixel structure is disposed on the insulating layer and extends into the opening to electrically connect to the active device, and the opening of the insulating layer overlaps with the second spacer.

[0018] In a display panel according to an embodiment of the present invention, the pixel structures further include a second pixel structure, the color filter patterns further include a second color filter pattern, and the reflective electrode of the second pixel structure overlaps the second color filter pattern. An orthographic projection area of the first color filter pattern on the substrate surface of the second substrate is different from an orthographic projection area of the second color filter pattern on the substrate surface.

[0019] Based on the above, in a display panel according to one embodiment of the present invention, multiple spacers are disposed between the first and second substrates to control the thickness of the liquid crystal layer. Because at least a portion of these spacers does not overlap with the multiple color filter patterns, the effect on the transmittance of the color filter patterns is effectively reduced, thereby ensuring the color performance of the display panel.

The claims and the specification may not use the same terminology; thus, the first element in the specification may be the second element in the claim.

[0076] Figure 1 and Figure 2 FIG. 1 is a schematic front view of a portion of film layers of a display panel according to a first embodiment of the present invention. Figure 3 yes Figure 1 Schematic cross-sectional view of a display panel. Figure 3 Corresponding to Figure 1 and Figure 2 For clarity, Figure 1 Only shown Figure 3 Part of the film layer on the first substrate 101, and Figure 2 Only shown Figure 3 Part of the film layer on the second substrate 102.

[0077] Please refer to Figures 1 to 3 The display panel 10 includes a first substrate 101, a second substrate 102, a plurality of data lines DL, a plurality of scan lines GL, a plurality of pixel structures PX, and a liquid crystal layer LCL. The first substrate 101 and the second substrate 102 are arranged to overlap each other, and the liquid crystal layer LCL is arranged between the first substrate 101 and the second substrate 102. The overlapping relationship here, for example, refers to the overlap of the first substrate 101 and the second substrate 102 along the normal direction of the substrate surface 102s of the second substrate 102 (for example, direction D3). Unless otherwise specified below, the overlapping relationship between the two components is defined in this manner, and the overlapping direction will not be repeated.

[0078] In this embodiment, a plurality of data lines DL are arranged on the first substrate 101 at intervals along a direction D1 and extend in a direction D2, while a plurality of scan lines GL are arranged on the first substrate 101 at intervals along a direction D2 and extend in the direction D1. More specifically, the scan lines GL intersect with the data lines DL and define a plurality of pixel regions of the display panel 10.

[0079] A plurality of pixel structures PX are disposed within the pixel regions and are each electrically connected to a scan line GL and a data line DL. For example, the pixel structures PX may be arranged in a plurality of rows and columns along directions D1 and D2, respectively. In other words, the pixel structures PX are arranged in an array on the first substrate 101.

[0080] In detail, each of these pixel structures PX may include an active device T and a reflective electrode RE electrically connected to each other. In this embodiment, the method for forming the active device T may include the following steps: forming a gate electrode GE, a gate insulating layer 110, a semiconductor pattern SC, a source electrode SE, and a drain electrode DE in sequence on a first substrate 101. The semiconductor pattern SC is arranged to overlap the gate electrode GE. The source electrode SE and the drain electrode DE overlap the semiconductor pattern SC and are in electrical contact with two different regions of the semiconductor pattern SC. In this embodiment, the gate electrode GE of the active device T may optionally be arranged below the semiconductor pattern SC to form a bottom-gate thin film transistor (TFT), but is not limited to this. In other embodiments, the gate electrode of the active device may also be optionally arranged above the semiconductor pattern to form a top-gate thin film transistor (TFT).

[0081] Furthermore, the active element T may be sequentially covered with an insulating layer 120 and an insulating layer 130. In this embodiment, the insulating layer 120 is, for example, a passivation layer, and the insulating layer 130 is, for example, a planarization layer. For example, in this embodiment, the pixel structure PX may further include a common electrode CE, a capacitor electrode CPE, and a conductive pattern CP that overlap with each other, but is not limited to this. The common electrode CE is disposed between the first substrate 101 and the gate insulating layer 110. The capacitor electrode CPE is disposed between the gate insulating layer 110 and the insulating layer 120. Therefore, the capacitor electrode CPE, the common electrode CE, and the gate insulating layer 110 sandwiched therebetween may form a storage capacitor. In other embodiments, the pixel structure PX may not include the common electrode CE and the capacitor electrode CPE that overlap with each other. The conductive pattern CP is disposed between the insulating layer 120 and the insulating layer 130.

[0082] In this embodiment, the insulating layer 130 has an opening OP, and this opening OP exposes a portion of the surface of the conductive pattern CP. The reflective electrode RE of the pixel structure PX is disposed on the surface of the insulating layer 130 and is electrically connected to the conductive pattern CP through the opening OP of the insulating layer 130. The conductive pattern CP is electrically connected to the capacitor electrode CPE through the contact hole TH of the insulating layer 120, and the capacitor electrode CPE may extend from the drain DE of the active device T (i.e., the drain DE and the capacitor electrode CPE are coupled to each other), but is not limited to this. In other embodiments, the pixel structure PX may not include the conductive pattern CP, and the reflective electrode RE may be electrically connected to the drain DE of the active device T through a through-hole penetrating the insulating layer 130 and the insulating layer 120.

[0083] It should be noted that the gate GE, source SE, drain DE, semiconductor pattern SC, gate insulating layer 110, passivation layer (i.e., insulating layer 120) and planarization layer (i.e., insulating layer 130) can be respectively realized by any gate, any source, any drain, any semiconductor pattern, any gate insulating layer, any passivation layer and any planarization layer for a reflective display panel known to any person skilled in the art, and the gate GE, source SE, drain DE, semiconductor pattern SC, gate insulating layer 110, passivation layer and planarization layer can be respectively formed by any method known to any person skilled in the art, and therefore will not be described in detail here.

[0084] Furthermore, the display panel 10 further includes a plurality of color filter patterns disposed on the second substrate 102 and respectively overlapping the plurality of reflective electrodes RE of the plurality of pixel structures PX. In this embodiment, the plurality of color filter patterns include, for example, a color filter pattern CFP1, a color filter pattern CFP2, and a color filter pattern CFP3, and each of the three color filter patterns filters different colors. For example, the color filter pattern CFP1 is adapted to allow red light to pass through, the color filter pattern CFP2 is adapted to allow green light to pass through, and the color filter pattern CFP3 is adapted to allow blue light to pass through (i.e., the color filter pattern CFP1 may include a red color resist, the color filter pattern CFP2 may include a green color resist, and the color filter pattern CFP3 may include a blue color resist).

[0085] The color filter pattern CFP1, the color filter pattern CFP2 and the color filter pattern CFP3 respectively overlap the pixel structure PX1, the pixel structure PX2 and the pixel structure PX3 of the plurality of pixel structures PX. In the present embodiment, each pixel unit P includes three pixel structures PX, that is, the pixel structure PX1, the pixel structure PX2 and the pixel structure PX3, wherein the pixel structure PX1, the pixel structure PX2 and the pixel structure PX3 respectively overlap the color filter pattern CFP1, the color filter pattern CFP2 and the color filter pattern CFP3 of different colors to display different colors, but not limited to this. For example, each pixel structure PX may be a pixel structure of a subpixel, and each pixel unit P may be a pixel structure of a pixel, which includes a pixel structure of three subpixels. In other embodiments, the number of pixel structures PX in each pixel unit P may be greater than 3 or less than 3. It is particularly noted that, Figure 1 Only a front view schematic diagram of a pixel unit P is shown. The display panel 10 may have a plurality of pixel units P arranged along the direction D1 and the direction D2. The front view schematic diagram of each pixel unit P can be referred to. Figure 1 The percentage value (also referred to as the first percentage value) of the orthographic projection area of the color filter pattern CFP1 on the reflective surface RS (i.e., the first reflective surface) of the reflective electrode RE of the pixel structure PX1 to the area of the first reflective surface, the percentage value (also referred to as the second percentage value) of the orthographic projection area of the color filter pattern CFP2 on the reflective surface RS (i.e., the second reflective surface) of the reflective electrode RE of the pixel structure PX2 to the area of the second reflective surface, and the percentage value (also referred to as the third percentage value) of the orthographic projection area of the color filter pattern CFP3 on the reflective surface RS (i.e., the third reflective surface) of the reflective electrode RE of the pixel structure PX3 to the area of the third reflective surface can be different from each other, or two of the first to third percentage values can be the same and different from the other percentage value, so as to meet specific color performance requirements. From another perspective, the orthographic projection areas of the color filter patterns CFP1, CFP2, and CFP3 on the substrate surface 102s of the second substrate 102 may be different from each other, or two of the orthographic projection areas of the color filter patterns CFP1, CFP2, and CFP3 on the substrate surface 102s of the second substrate 102 may be the same and different from the other orthographic projection area.

[0086] For example, in this embodiment, the color filter patterns are ranked according to their orthographic projection areas on the substrate surface 102s of the second substrate 102, in descending order: color filter pattern CFP3, color filter pattern CFP1, and color filter pattern CFP2, but this is not limiting. For example, in other embodiments, the orthographic projection area of color filter pattern CFP1 on the substrate surface 102s of the second substrate 102 may be equal to the orthographic projection area of color filter pattern CFP2 on the substrate surface 102s of the second substrate 102, and the orthographic projection area of color filter pattern CFP3 on the substrate surface 102s of the second substrate 102 may be larger than the orthographic projection areas of color filter pattern CFP1 and color filter pattern CFP2 on the substrate surface 102s of the second substrate 102, but this is not limiting.

[0087] Furthermore, in this embodiment, the display panel 10 may optionally include a plurality of light-transmitting patterns disposed on the second substrate 102, and these light-transmitting patterns may overlap with the plurality of reflective electrodes RE of the plurality of pixel structures PX, but is not limited thereto. Figures 1 to 3 As shown, the multiple light-transmitting patterns include, for example, light-transmitting pattern TP1, light-transmitting pattern TP2, and light-transmitting pattern TP3, and light-transmitting pattern TP1, light-transmitting pattern TP2, and light-transmitting pattern TP3 overlap pixel structure PX1, pixel structure PX2, and pixel structure PX3 of the multiple pixel structures PX, respectively. In a pixel structure PX that overlaps a color filter pattern and a light-transmitting pattern, a portion of the reflective electrode RE of pixel structure PX overlaps the color filter pattern but does not overlap the light-transmitting pattern, and another portion of the reflective electrode RE overlaps the light-transmitting pattern but does not overlap the color filter pattern. It is particularly noted that the light-transmitting pattern is suitable for allowing light of multiple colors to pass through, for example, red light, green light, and blue light to pass through the light-transmitting pattern. In some embodiments, the light-transmitting pattern may, for example, comprise transparent photoresist, but is not limited thereto. In the present embodiment, each pixel structure PX in a pixel unit P is correspondingly provided with a light-transmitting pattern, that is, the pixel structure PX1, the pixel structure PX2, and the pixel structure PX3 overlap the light-transmitting pattern TP1, the light-transmitting pattern TP2, and the light-transmitting pattern TP3, respectively, but the present invention is not limited thereto. In other embodiments, one or two of the pixel structures PX1, the pixel structure PX2, and the pixel structure PX3 in a pixel unit P are correspondingly provided with a light-transmitting pattern, while the others are not provided with a light-transmitting pattern. For example, the pixel structure PX1 and the pixel structure PX2 may both overlap the light-transmitting pattern, but the pixel structure PX3 does not overlap the light-transmitting pattern. In the present embodiment, the light-transmitting patterns are sorted according to the size of the orthographic projection area on the substrate surface 102s of the second substrate 102, and are arranged from largest to smallest in the order of light-transmitting pattern TP2, light-transmitting pattern TP1, and light-transmitting pattern TP3, but the present invention is not limited thereto.

[0088] It should be noted that in this embodiment, the color filter pattern and the light-transmitting pattern are both disposed on the second substrate 102 and located between the substrate surface 102s of the second substrate 102 and the liquid crystal layer LCL, but this is not limiting. In other embodiments, the color filter pattern and the light-transmitting pattern may be disposed on the second substrate 102 and located on the substrate surface of the second substrate 102 facing away from the liquid crystal layer LCL (i.e., the substrate surface of the second substrate 102 opposite to the substrate surface 102s). In still other embodiments, the color filter pattern and the light-transmitting pattern may be disposed on the first substrate 101 and located between the reflective electrode RE of the pixel structure PX and the liquid crystal layer LCL.

[0089] In this document, one, another, and the remaining one of the pixel structure PX1, the pixel structure PX2, and the pixel structure PX3 may be referred to as the first pixel structure, the second pixel structure, and the third pixel structure, respectively; one, another, and the remaining one of the color filter patterns CFP1, CFP2, and CFP3 may be referred to as the first color filter pattern, the second color filter pattern, and the third color filter pattern, respectively; and one, another, and the remaining one of the light-transmitting patterns TP1, TP2, and TP3 may be referred to as the first light-transmitting pattern, the second light-transmitting pattern, and the third light-transmitting pattern, respectively. Figure 2 The color filter patterns CFP1, CFP2, and CFP3 are sequentially arranged along the direction D1, and the light-transmitting patterns TP1, TP2, and TP3 are sequentially arranged along the direction D1 as an example. However, the arrangement order of the color filter patterns CFP1, CFP2, and CFP3 and the light-transmitting patterns TP1, TP2, and TP3 in this embodiment is not limited to this.

[0090] To create a cavity between the first substrate 101 and the second substrate 102 capable of accommodating the liquid crystal layer LCL, the display panel 10 further includes a plurality of spacers SP. In this embodiment, these spacers SP may be disposed on the second substrate 102 (i.e., the spacers SP are located between the second substrate 102 and the second alignment layer AL2) and overlap the plurality of reflective electrodes RE (i.e., the orthographic projections of these spacers SP on the substrate surface 102s of the second substrate 102 are located within the orthographic projections of the plurality of reflective electrodes RE on the substrate surface 102s). However, the present invention is not limited to this. In other embodiments, the spacers SP may be disposed on the first substrate 101 (i.e., the spacers SP are located between the first substrate 101 and the first alignment layer AL1).

[0091] In this embodiment, a plurality of spacers SP are respectively overlapped with a plurality of light-transmitting patterns (e.g., light-transmitting pattern TP1, light-transmitting pattern TP2, and light-transmitting pattern TP3). More specifically, the orthographic projections of these spacers SP on the substrate surface 102s of the second substrate 102 are within the orthographic projections of the plurality of light-transmitting patterns on the substrate surface 102s. That is, each spacer SP can completely overlap with a corresponding light-transmitting pattern (e.g., Figure 2 As shown in FIG. 1 , the problem of reduced transmittance of the color filter pattern caused by the provision of the spacer SP can be avoided, thereby ensuring the color performance of the display panel 10 .

[0092] For example, in this embodiment, a common electrode layer CEL and a coating layer 150 may also be provided on the second substrate 102, but the present invention is not limited thereto. In other embodiments, the common electrode layer may be provided on the first substrate 101, that is, between the first substrate 101 and the liquid crystal layer LCL. The common electrode layer CEL may be a transparent conductive layer, which includes a transparent conductive material. For example, the common electrode layer CEL may include an indium oxide, such as but not limited to indium tin oxide (ITO). The coating layer 150 covers a plurality of color filter patterns and light-transmitting patterns, and the common electrode layer CEL is provided on the coating layer 150. The electric field generated between the common electrode layer CEL and the reflective electrode RE is suitable for driving the plurality of liquid crystal molecules (not shown) of the liquid crystal layer LCL to rotate and form an arrangement state corresponding to the direction and intensity of the electric field. By changing the arrangement state of these liquid crystal molecules, the polarization state of the light passing through the liquid crystal layer LCL is changed to form a light output brightness corresponding to the arrangement state.

[0093] In order to orient the arrangement of the multiple liquid crystal molecules in the liquid crystal layer LCL in a natural state (i.e., without being affected by external forces), a first alignment layer AL1 covering the multiple reflective electrodes RE may be further provided on the first substrate 101, and a second alignment layer AL2 covering the common electrode layer CEL may be further provided on the second substrate 102. The liquid crystal layer LCL is sandwiched between the first alignment layer AL1 and the second alignment layer AL2. For example, in this embodiment, the first alignment direction AD1 of the first alignment layer AL1 may be antiparallel to the second alignment direction AD2 of the second alignment layer AL2, for example, the liquid crystal layer LCL may be driven in an electrically controlled birefringence (ECB) mode. However, the present invention is not limited thereto. In other embodiments, the first alignment direction AD1 may be perpendicular to the second alignment direction AD2, for example, the liquid crystal layer LCL may be driven in a twisted nematic (TN) mode.

[0094] In this embodiment, the display panel 10 may be a reflective display panel, and the reflective electrode RE may reflect ambient light or light from the front light module to display the corresponding image. Since the incident light and the reflected light each pass through the common electrode layer CEL once, the image may appear yellowish. For example, when the common electrode layer CEL includes indium tin oxide and the thickness of the common electrode layer CEL is 1200 angstroms to 1700 angstroms, the b* value of the color coordinate of the light passing through the common electrode layer CEL may be approximately 2 to 11, which may cause the image to appear yellowish. The yellowish problem can be solved by configuring the area of the color filter pattern described above and matching it with the complementary color of the translucent pattern. In addition, in this embodiment, the spacer SP is overlapped with the translucent pattern to avoid affecting the penetration area of the color filter pattern, thereby maintaining the NTSC (National Television System Committee) range of the display panel 10.

[0095] Other embodiments will be listed below to illustrate the present disclosure in detail, wherein the same components will be marked with the same symbols, and the description of the same technical content will be omitted. For the omitted parts, please refer to the above embodiments and will not be repeated below.

[0096] Figure 4 and Figure 5 FIG. 1 is a schematic front view of a portion of film layers of a display panel according to a second embodiment of the present invention. Figure 6 yes Figure 4 Schematic cross-sectional view of a display panel. Figure 6 Corresponding to Figure 4 and Figure 5 For clear presentation, Figure 4 Only shown Figure 6 Part of the film layer on the first substrate 101, and Figure 5 Only shown Figure 6 Part of the film layer on the second substrate 102.

[0097] Please refer to Figures 4 to 6 The display panel 11 of this embodiment is Figure 1 and Figure 2 The difference between the display panel 10 and the display panel 11 lies in the different configuration of the spacers. For example, in this embodiment, a portion of the spacers in the display panel 11 may be arranged to overlap the color filter pattern, and another portion of the spacers in the display panel 11 may be arranged to overlap the light-transmitting pattern. More specifically, the multiple spacers in the display panel 11 may include spacers SP1, SP2, and SP3 that overlap the pixel structure PX1, pixel structure PX2, and pixel structure PX3, respectively. One or two of the spacers SP1, SP2, and SP3 in a pixel unit P overlap the light-transmitting pattern, and the remaining spacers SP1, SP2, and SP3 in the pixel unit overlap the color filter pattern.

[0098] It is particularly noted that in this embodiment, the following configuration is used as an example, that is, the spacers SP1 and SP3 are respectively arranged to overlap the light-transmitting pattern TP1 and the light-transmitting pattern TP3, and do not overlap the color filter pattern CFP1 and the color filter pattern CFP3. However, the spacer SP2 is arranged to overlap the color filter pattern CFP2 and does not overlap the light-transmitting pattern TP2. The position configuration of the spacers in this embodiment is not based on Figure 5 Limited to.

[0099] Furthermore, the orthographic projection areas of at least two of the spacers SP1, SP2, and SP3 on the substrate surface 102s of the second substrate 102 may be different from one another. Specifically, in this embodiment, the following configuration is used as an example, where the orthographic projection areas of the spacer SP1, the spacer SP2, and the spacer SP3 on the substrate surface 102s may be different from one another. For example, in this embodiment, since the spacer SP2 is disposed overlapping the second color filter pattern CFP2, the orthographic projection area of the spacer SP2 on the substrate surface 102s may be smaller than the orthographic projection areas of the spacer SP1 and the orthographic projection areas of the spacer SP3 on the substrate surface 102s to reduce the effect of the spacer SP2 on the transmittance of the second color filter pattern CFP2. Furthermore, the orthographic projection area of the spacer SP1 on the substrate surface 102s may be larger than the orthographic projection area of the spacer SP3 on the substrate surface 102s to adjust the color gamut of the display panel 11, but the present invention is not limited thereto.

[0100] Furthermore, the heights of at least two of the spacers SP1, SP2, and SP3 along the normal direction (e.g., direction D3) to the substrate surface 102s may differ from each other. Specifically, in this embodiment, the following configuration is used as an example: a first height H1 of the spacer SP1 along the normal direction (e.g., direction D3) may differ from a second height H2 of the spacer SP3 along the normal direction to the substrate surface 102s. For example, the first height H1 of the spacer SP1 may be greater than the second height H2 of the spacer SP2. The height configuration of the spacers in this embodiment is not limited to the above description. By designing at least two of the spacers SP1, SP2, and SP3 to have different heights, the cell gaps in regions with spacers of different heights can be slightly different, thereby further adjusting the color gamut of the display panel 11.

[0101] By designing the spacers at different heights, areas, and positions, the color gamut performance of the display panel 11 can be adjusted with greater flexibility, thereby adjusting the optimal NTSC range and transmittance of the display panel 11 to meet different product application requirements.

[0102] Figure 7 is a schematic front view of a portion of the film layers of a display panel according to a third embodiment of the present invention. Figure 7 Except for the film layers shown, the film layer structure of the display panel 12 on the first substrate and the remaining film layer structures on the second substrate are similar to those shown in FIG. Figure 1 Therefore, for the illustration and description of these film layer structures, please refer to the relevant paragraphs and corresponding drawings of the aforementioned embodiments.

[0103] Please refer to Figure 1 、 Figure 3 and Figure 7 , the display panel 12 of this embodiment and Figure 2 The difference between the display panel 10 and the display panel 10 is that the configuration profile of the spacer is different. For example, in this embodiment, the orthographic projection profile of each of the multiple spacers SP-A on the substrate surface 102s of the second substrate 102 is in the shape of an elongated strip, and the extension direction of each spacer SP-A is parallel to the second alignment direction AD2 of the second alignment layer AL2. Accordingly, the shape of the spacer SP-A of this embodiment can effectively reduce the poor alignment area of the second alignment layer AL2 caused by the setting of the spacer SP-A (for example, during the friction alignment, a weak alignment area is formed near the spacer due to the setting of the spacer), which helps to reduce the dark state light leakage of the display panel 12, thereby improving the display contrast and the NTSC of the display panel 12. In particular, Figure 1 、 Figure 3 and Figure 7 The example of the spacers SP-A being disposed on the second substrate 102 (i.e., the spacers SP-A are located between the second substrate 102 and the second alignment layer AL2) is used, but is not limited thereto. In other embodiments, the spacers SP-A may be disposed on the first substrate 101 (i.e., the spacers SP-A are located between the first substrate 101 and the first alignment layer AL1). The orthographic projection of each of the multiple spacers SP-A on the surface of the first substrate 101 facing the liquid crystal layer LCL is elongated, and the extension direction of each spacer SP-A is parallel to the first alignment direction AD1 of the first alignment layer AL1. This effectively reduces the misaligned areas in the first alignment layer AL1 caused by the spacers.

[0104] Figure 8 FIG. 4 is a schematic front view of a portion of film layers of a display panel according to a fourth embodiment of the present invention. Figure 9 yes Figure 8A front view schematic diagram of a modified embodiment of a partial film layer of a display panel. Figure 10 yes Figure 8 A front view schematic diagram of another variant embodiment of a partial film layer of a display panel. First, it is explained that, in addition to Figure 8 Except for the film layers shown, the film layer structure of the display panel 13 on the first substrate and the remaining film layer structures on the second substrate are similar to Figure 1 Therefore, for the illustration and description of these film layer structures, please refer to the relevant paragraphs and corresponding drawings of the aforementioned embodiments.

[0105] Please refer to Figure 1 、 Figure 3 and Figure 8 The display panel 13 of this embodiment is Figure 2 The difference between the display panel 10 and the display panel 10 is that the configuration profile and position of the spacer are different. For example, in this embodiment, the orthographic projection profile of each of the plurality of spacers SP-B on the substrate surface 102s of the second substrate 102 is in the shape of a long strip. It is particularly noteworthy that each of these spacers SP-B is partially disposed between the reflective electrodes RE of two adjacent pixel structures PX (i.e., the spacer SP-B partially overlaps the area between the reflective electrodes RE of two adjacent pixel structures PX in the direction D3), and each spacer SP-B also overlaps the reflective electrode RE of at least one of the two adjacent pixel structures PX ( Figure 1 and Figure 8 (For example, each of these spacers SP-B also overlaps with the reflective electrodes RE of two adjacent pixel structures PX.) More specifically, a portion of a spacer SP-B is disposed between the reflective electrodes RE of two adjacent pixel structures PX, and another portion of the spacer SP-B overlaps with the reflective electrode of at least one of the two adjacent pixel structures PX. In addition, the other portion of the spacer SP-B also overlaps with at least one of two adjacent color filter patterns (e.g., color filter patterns CFP1 to CFP3) and at least one of two adjacent light-transmitting patterns (e.g., light-transmitting patterns TP1 to TP3). Figure 8 (This is exemplified by the case where the other portion of the spacer SP-B also overlaps two adjacent color filter patterns and two adjacent light-transmitting patterns.) Thus, the effect on the transmittance of the color filter patterns can be effectively reduced, thereby ensuring the color performance of the display panel 13.

[0106] For example, dark-state light leakage can occur because the alignment of at least a portion of the liquid crystal layer LCL located between two adjacent pixel structures PX (i.e., the area between two adjacent reflective electrodes RE) cannot be controlled by the reflective electrodes RE. Furthermore, in this embodiment, the voltage polarities of the two adjacent reflective electrodes RE arranged along direction D1 can be opposite within the same frame period. That is, the reflective display panel 13 is driven, for example, using a row inversion or dot inversion electrical architecture, but is not limited thereto. The liquid crystal layer LCL driven based on the aforementioned electrical architecture is susceptible to liquid crystal molecule alignment inversion in the area between two adjacent pixel structures PX, leading to dark-state light leakage. Therefore, by disposing spacers SP-B between two adjacent pixel structures PX, light leakage can be significantly improved when the reflective display panel 13 is operating in the dark state, thereby enhancing its display contrast. From another perspective, this increases the flexibility in selecting the driving electrical architecture for the reflective display panel 13.

[0107] On the other hand, in this embodiment, the extension direction of each spacer SP-B is parallel to the second alignment direction AD2 of the second alignment layer AL2. Therefore, the poor alignment area of the second alignment layer AL2 caused by the provision of the spacer SP-B can be effectively reduced, which helps to reduce the dark state light leakage of the display panel 13, thereby improving the display contrast. In particular, Figure 1 、 Figure 3 and Figure 8 The example in which the spacers SP-B are disposed on the second substrate 102 (i.e., the spacers SP-B are located between the second substrate 102 and the second alignment layer AL2) is used, but the present invention is not limited thereto. In other embodiments, the spacers SP-B may be disposed on the first substrate 101 (i.e., the spacers SP-B are located between the first substrate 101 and the first alignment layer AL1), with the extension direction of each spacer SP-B parallel to the first alignment direction AD1 of the first alignment layer AL1. This effectively reduces the misaligned areas in the first alignment layer AL1 caused by the spacers.

[0108] However, the present invention is not limited thereto. Figure 1 、 Figure 3 and Figure 9 In a display panel 13A of a modified embodiment, in addition to the extension direction of the spacer SP-C being parallel to the second alignment direction AD2, the width W of at least one end SPe along the extension direction gradually decreases toward the second alignment direction AD2 or a direction antiparallel to the second alignment direction AD2. Figure 9In the embodiment, the widths W of the two ends SPe of the spacer SP-C on opposite sides of the extension direction gradually decrease toward the second alignment direction AD2 and toward the direction antiparallel to the second alignment direction AD2. This can further reduce the misaligned area of the second alignment layer AL2 caused by the spacer SP-C, helping to reduce dark-state light leakage of the display panel 13A, thereby improving display contrast. In particular, Figure 1 、 Figure 3 and Figure 9 The example of spacers SP-C disposed on the second substrate 102 is used, but the present invention is not limited thereto. In other embodiments, the spacers SP-C may be disposed on the first substrate 101, with each spacer SP-C extending in a direction parallel to the first alignment direction AD1 of the first alignment layer AL1. Furthermore, the widths of the two opposite ends of the spacer SP-C along the extension direction gradually decrease toward the first alignment direction AD1 and in a direction antiparallel to the first alignment direction AD1, respectively. This effectively reduces the misalignment region in the first alignment layer AL1 caused by the spacers.

[0109] Please refer to Figure 1 、 Figure 3 and Figure 10 In another variant embodiment of the display panel 13B, the orthographic projection profile of each of the plurality of spacers SP-D on the second substrate 102 is dot-shaped. Each of these spacers SP-D is partially disposed between the reflective electrodes RE of two adjacent pixel structures PX (i.e., the spacer SP-D partially overlaps the region between the reflective electrodes RE of two adjacent pixel structures PX in the direction D3), and each spacer SP-D also overlaps the reflective electrode RE of at least one of the two adjacent pixel structures PX ( Figure 10 (This is taken as an example in which each of these spacers SP-D also overlaps with the reflective electrodes RE of two adjacent pixel structures PX.) More specifically, a portion of each spacer SP-D is disposed between the reflective electrodes RE of two adjacent pixel structures PX, and another portion of each spacer SP-D overlaps with the reflective electrode of at least one of the two adjacent pixel structures PX. A portion of each of these spacers SP-D disposed between two adjacent pixel structures PX also overlaps with at least one of two adjacent color filter patterns (e.g., color filter patterns CFP1 to CFP3), and another portion of each spacer SP-D also overlaps with at least one of two adjacent light-transmitting patterns (e.g., light-transmitting patterns TP1 to TP3). Figure 10In this example, a portion of the spacers SP-D disposed between two adjacent pixel structures PX overlaps with two adjacent color filter patterns, while another portion overlaps with two adjacent light-transmitting patterns. This effectively reduces the effect on the transmittance of the color filter patterns, thereby ensuring the color performance of the display panel 13B.

[0110] Figure 11 and Figure 12 FIG. 4 is a schematic front view of a portion of film layers of a display panel according to a fifth embodiment of the present invention. Figure 13 yes Figure 11 Schematic cross-sectional view of a display panel. Figure 13 Corresponding to Figure 11 and Figure 12 For clear presentation, Figure 11 Only shown Figure 13 Part of the film layer on the first substrate 101, and Figure 12 Only shown Figure 13 Part of the film layer on the second substrate 102.

[0111] Please refer to Figures 11 to 13 The display panel 14 of this embodiment is Figures 1 to 3 The difference between the display panel 10 and the display panel 14 lies in the different spacer configurations. For example, in this embodiment, in addition to the multiple spacers SP arranged in an overlapping light-transmitting pattern, the display panel 14 may further include multiple spacers SP". Of particular note, these spacers SP" may overlap with the opening OP of the insulating layer 130 in direction D3. More specifically, the orthographic projection of the opening OP on the first substrate 101 overlaps with the orthographic projection of the spacer SP" on the first substrate 101, or the orthographic projection of the opening OP on the second substrate 102 overlaps with the orthographic projection of the spacer SP" on the second substrate 102. Because the first alignment layer AL1 is recessed near the opening OP due to the shape of the opening OP, the alignment process of the first alignment layer AL1 results in weak alignment near the opening OP, leading to light leakage in the dark state. Furthermore, the alignment of the liquid crystal layer LCL near the opening OP is affected by the surface topography of the insulating layer 130 defining the opening OP, which can easily lead to poor alignment of the liquid crystal molecules, resulting in light leakage in the dark state. Therefore, by disposing the spacers SP", the light leakage range of the display panel 14 can be reduced. In addition, the disposition of these spacers SP" can further increase the distribution density of the spacers to improve the anti-pressing ability of the display panel 14. It is particularly noted that the spacers SP" of this embodiment can also be applied to the second embodiment. For example, Figure 5 A spacer SP" may also be included, the position of which corresponds to Figure 4 The opening of OP.

[0112] Figure 14 is a schematic front view of a portion of the film layers of a display panel according to a sixth embodiment of the present invention. Figure 14 Except for the film layers shown, the film layer structure of the display panel 15 on the first substrate and the remaining film layer structures on the second substrate are similar to those shown in FIG. Figure 1 Therefore, for the illustration and description of these film layer structures, please refer to the relevant paragraphs and corresponding drawings of the aforementioned embodiments.

[0113] Please refer to Figure 1 、 Figure 3 and Figure 14 The display panel 15 of this embodiment is Figures 1 to 3 The difference of the display panel 10 is that the configuration profile and position of the spacer are different. In this embodiment, a plurality of spacers SP-E overlap with a plurality of reflective electrodes RE, and do not overlap with a plurality of color filter patterns and a plurality of light-transmitting patterns. In this embodiment, the pixel structures PX1, PX2, and PX3 of a pixel unit P have color filter patterns CFP1, CFP2, and CFP3, respectively, and at least one of the pixel structures PX1, PX2, and PX3 also has a spacer SP-E and a light-transmitting pattern that do not overlap with each other. More specifically, these spacers SP-E can be used to replace Figure 2 The light-transmitting pattern in the middle part is formed as Figure 14 The configuration diagram of the color filter pattern, the light-transmitting pattern and the spacer is shown. It is particularly noted that in this embodiment, the following configuration is used as an example, for example: Figure 2 Part of the area where the light-transmitting patterns TP1 and TP3 are set is replaced by the spacer SP-E of this embodiment to form the following Figure 14 In a configuration, pixel structure PX1 is provided with non-overlapping color filter pattern CFP1, transmissive pattern TP1-A, and spacer SP-E, and pixel structure PX3 is provided with non-overlapping color filter pattern CFP3, transmissive pattern TP3-A, and spacer SP-E, respectively. However, this configuration is not limiting. From another perspective, the reflective electrode RE of a pixel structure PX includes a first portion, a second portion, and a third portion that do not overlap. The first portion of the reflective electrode RE overlaps the color filter pattern in direction D3 but does not overlap the transmissive pattern or spacer SP-E. The second portion of the reflective electrode RE overlaps the spacer SP-E in direction D3 but does not overlap the color filter pattern or transmissive pattern. The third portion of the reflective electrode RE overlaps the transmissive pattern in direction D3 but does not overlap the color filter pattern or spacer SP-E. This configuration not only improves the transmittance reduction of the transmissive pattern caused by the spacer, thereby increasing brightness, but also enhances the NTSC and color performance of the display panel 15.

[0114] Figure 15FIG. 1 is a schematic front view of a portion of the film layers of a display panel according to a seventh embodiment of the present invention. Figure 15 Except for the film layers shown, the film layer structure of the display panel 16 on the first substrate and the remaining film layer structures on the second substrate are similar to Figure 1 Therefore, for the illustration and description of these film layer structures, please refer to the relevant paragraphs and corresponding drawings of the aforementioned embodiments.

[0115] Please refer to Figure 1 、 Figure 3 and Figure 15 The display panel 16 of this embodiment is Figures 1 to 3 The difference between the display panel 10 and the display panel 16 is that at least one of the pixel structures PX1, PX2, and PX3 of the display panel 10 is provided with a corresponding light-transmitting pattern, while none of the pixel structures PX1, PX2, and PX3 of the display panel 16 are provided with corresponding light-transmitting patterns, and spacers are provided in the areas of the pixel structures PX1, PX2, and PX3 of the display panel 16 that do not correspond to the color filter pattern. In this embodiment, multiple pixel structures have color filter patterns but no light-transmitting patterns, and multiple spacers overlap the multiple reflective electrodes RE and do not overlap the multiple color filter patterns. More specifically, these spacers can be used to replace all of the light-transmitting patterns in the first embodiment, for example: Figure 2 The light-transmitting pattern TP1, light-transmitting pattern TP2, and light-transmitting pattern TP3 in the embodiment can be replaced by the spacers SP1-F, spacer SP2-F, and spacer SP3-F of the present embodiment, respectively. From another perspective, the reflective electrode RE of a pixel structure PX has a first portion and a second portion that do not overlap. The first portion of the reflective electrode RE overlaps the color filter pattern in direction D3 but does not overlap the spacer, and the second portion of the reflective electrode RE overlaps the spacer in direction D3 but does not overlap the color filter pattern. This not only improves the transmittance reduction of the light-transmitting pattern caused by the spacer, thereby increasing brightness, but also enhances the NTSC and color performance of the display panel 16.

[0116] Figure 16 FIG. 1 is a schematic front view of a portion of the film layers of a display panel according to an eighth embodiment of the present invention. Figure 16 Except for the film layers shown, the film layer structure of the display panel 17 on the first substrate and the remaining film layer structures on the second substrate are similar to Figure 1 Therefore, for the illustration and description of these film layer structures, please refer to the relevant paragraphs and corresponding drawings of the aforementioned embodiments.

[0117] Please refer to Figure 1 、 Figure 3 and Figure 16 The display panel 17 of this embodiment is Figures 1 to 3The difference between the display panel 10 and the display panel 10 is that the configuration profile and position of the spacer are different. For example, in this embodiment, the orthographic projection profile of each of the plurality of spacers SP-G on the substrate surface 102s of the second substrate 102 is a diamond shape. It is particularly noteworthy that each of these spacers SP-G is partially disposed between the reflective electrodes RE of two adjacent pixel structures PX (i.e., the spacer SP-G partially overlaps the area between the reflective electrodes RE of two adjacent pixel structures PX in the direction D3), and each spacer SP-G also overlaps the reflective electrode RE of at least one of the two adjacent pixel structures PX ( Figure 16 (This is an example in which each of these spacers SP-G also overlaps with the reflective electrodes RE of two adjacent pixel structures PX.) More specifically, a portion of each spacer SP-G is disposed between two adjacent pixel structures PX, and another portion of each spacer SP-G overlaps with the reflective electrode RE of at least one of the two adjacent pixel structures PX. In addition, at least a portion of each of these spacers SP-G disposed between two adjacent pixel structures PX may also overlap with at least one of two adjacent color filter patterns (e.g., color filter patterns CFP1 to CFP3), or may also overlap with at least one of two adjacent light-transmitting patterns (e.g., light-transmitting patterns TP1 to TP3). Figure 16 For example, at least a portion of the spacers SP-G disposed between two adjacent pixel structures PX overlaps with two adjacent color filter patterns, or overlaps with two adjacent light-transmitting patterns. This effectively reduces the effect on the transmittance of the color filter patterns, thereby increasing brightness and improving the NTSC and color performance of the display panel 17.

[0118] On the other hand, in this embodiment, the virtual line VC extending from two of the four corners of the orthographic projection profile (i.e., a diamond shape) of each spacer SP-G on the substrate surface 102s of the second substrate 102 is parallel to the second alignment direction AD2 of the second alignment layer AL2. Therefore, the misaligned area of the second alignment layer AL2 caused by the provision of the spacers SP-G can be effectively reduced, which helps reduce dark-state light leakage of the display panel 17, thereby improving the display contrast. In particular, Figure 1 、 Figure 3 and Figure 16The example of the spacers SP-G being disposed on the second substrate 102 is used, but the present invention is not limited thereto. In other embodiments, the spacers SP-G may be disposed on the first substrate 101, and the virtual line connecting two of the four corners of the orthographic projection profile (i.e., a diamond shape) of each spacer SP-G on the substrate surface of the first substrate 101 extends parallel to the first alignment direction AD1 of the first alignment layer AL1. This effectively reduces the misaligned regions in the first alignment layer AL1 caused by the spacers.

[0119] It is particularly noted that the above embodiments may be combined arbitrarily. For example, Figure 8 The interstitial material SP-B, Figure 9 The interstitial material SP-C, Figure 10 Interstitial material SP-D or Figure 16 The interstitial material SP-G can also be used for Figure 2 、 Figure 5 、 Figure 7 、 Figure 12 、 Figure 14 or Figure 15 In the embodiment, Figure 12 The interstitial material SP" can also be applied to Figure 2 、 Figure 5 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 14 、 Figure 15 or Figure 16 In the embodiment of .

[0120] In each of the above-described embodiments, the display panels 10-17 may be reflective display panels, and the reflective electrode RE defines a reflective region of the reflective display panel. Specifically, the reflective display panel of the present invention may be a fully reflective display panel having only a reflective region, or a transflective display panel having both a reflective region and a transmissive region (not shown).

[0121] In summary, in a display panel according to one embodiment of the present invention, multiple spacers are disposed between the first and second substrates to control the thickness of the liquid crystal layer. Because at least a portion of these spacers does not overlap with the multiple color filter patterns, their effect on the transmittance of the color filter patterns is effectively reduced, thereby ensuring optimal color performance of the display panel.

[0122] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
