[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This application claims priority from Japanese Patent Application No. 2023-179973, filed on October 19, 2023, the entire disclosure of which is incorporated herein by reference. Technical Field
[0003] The present disclosure generally relates to liquid crystal display devices. Background Art
[0004] In the related art, a liquid crystal display device having a plurality of liquid crystal display panels stacked on each other is known. For example, unexamined Japanese patent application publication No. 2023-000275 discloses a display device having a color display element (color liquid crystal element) and a liquid crystal display panel stacked with color display elements.
[0005] In Unexamined Japanese Patent Application Publication No. 2023-000275, a TFT substrate of a liquid crystal display panel has a plurality of first bus lines extending in a first direction and a plurality of second bus lines extending in a second direction intersecting the first direction. At least one of the plurality of first bus lines and at least one of the plurality of second bus lines overlap with sub-pixels of all colors included in a color liquid crystal element.
[0006] In Unexamined Japanese Patent Application Publication No. 2023-000275, a first bus extends while being bent toward a first direction, and a second bus extends while being bent toward a second direction, so that the first bus and the second bus overlap with sub-pixels of all colors of a color liquid crystal element. This suppresses the occurrence of moiré.
[0007] In the liquid crystal display panel of unexamined Japanese patent application publication No. 2023-000275, the switching element (thin film transistor) is located near the intersection of the first bus and the second bus. The area of the display unit (pixel) of the liquid crystal display panel is an integer multiple of the area of the pixel of the multiple sub-pixels including the color display element. Therefore, the switching elements of the liquid crystal display panel are arranged in the first direction and the second direction with wide intervals, and block the light incident on the color liquid crystal element from the backlight (when the color liquid crystal element is arranged on the observer side) or the light emitted from the color liquid crystal element (when the liquid crystal display panel is arranged on the observer side). When the switching element blocks light at wide intervals, the switching element protrudes, and the dark area caused by the switching element may be recognized by the observer as display inconsistency.
[0008] The present disclosure has been made in view of the above-described circumstances, and an object of the present disclosure is to provide a liquid crystal display device that suppresses moiré and also suppresses display non-uniformity caused by a light shielding member. Summary of the invention
[0009] In order to achieve the above object, the liquid crystal display device disclosed in the present invention includes:
[0010] a first liquid crystal display panel that displays a color display element and in which a first main pixel including a plurality of sub-pixels of different colors is arranged; and
[0011] a second liquid crystal display panel, which overlaps with the first liquid crystal display panel and displays a monochrome display element, and in which second primary pixels corresponding to the plurality of first primary pixels are arranged, wherein:
[0012] The second liquid crystal display panel includes a switch element driving a second main pixel and having a light-blocking property, a first light-blocking pattern extending along a predetermined first direction and repeatedly arranged and having a light-blocking property, a second light-blocking pattern extending along a predetermined second direction perpendicular to the first direction and repeatedly arranged and having a light-blocking property, and a plurality of light-shielding members having a light-blocking property.
[0013] The first light-blocking pattern includes a first light-blocking line and a second light-blocking line, the first light-blocking line extending in a first direction and including a first inclined portion inclined relative to the first direction and a second inclined portion inclined relative to the first direction in a direction opposite to the first inclined portion, and the second light-blocking line is adjacent to the first light-blocking line and is line-symmetrical with the first light-blocking line relative to the first direction,
[0014] The plurality of light-shielding members are each located in a region between a cross line and a symmetry axis of the first light-blocking pattern, the cross line connects the intersection of the first light-blocking pattern and the second light-blocking pattern and extends in the first direction, the region is surrounded by the first light-blocking pattern and the second light-blocking pattern, and the spacing between the first light-blocking line and the second light-blocking line continuously widens from both ends of the region in the first direction, and
[0015] At least one of the first blocking line and the second blocking line is formed by a scanning wiring of the second liquid crystal display panel.
[0016] It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are not restrictive of the disclosure.
[0017] According to the present disclosure, the first light-blocking pattern includes a first light-blocking line and a second light-blocking line, the first light-blocking line includes a first inclined portion inclined relative to a first direction and a second inclined portion inclined relative to the first direction in a direction opposite to the first inclined portion, and the second light-blocking line is adjacent to the first light-blocking line and is line-symmetrical with the first light-blocking line relative to the first direction. Therefore, moiré can be suppressed. In addition, each of the light-blocking members is located in a region between a cross line and an axis of symmetry of the first light-blocking pattern, the cross line connecting the intersection of the first light-blocking pattern and the second light-blocking pattern and extending in the first direction, the region being a region surrounded by the first light-blocking pattern and the second light-blocking pattern, and wherein the spacing between the first light-blocking line and the second light-blocking line is continuously widened in the first direction from both ends of the region. As a result, the spacing between the dark areas caused by the switching element and the light-blocking member is narrowed, and therefore, the display inconsistency caused by the dark areas can be suppressed.

[0046] Hereinafter, a liquid crystal display device according to various embodiments is described with reference to the accompanying drawings.
[0047] Example 1
[0048] Reference Figures 1 to 13 A liquid crystal display device 10 according to the present embodiment is described. The liquid crystal display device 10 displays color display elements (characters, images, patterns, and the like) using a first liquid crystal display panel 100 and a second liquid crystal display panel 200 described later.
[0049] like Figure 1 As shown, the liquid crystal display device 10 includes a panel portion 50, a backlight 300, and a display controller 400. The panel portion 50 includes a first liquid crystal display panel 100 and a second liquid crystal display panel 200. The backlight 300 is a light source that emits light on the first liquid crystal display panel 100 and the second liquid crystal display panel 200. The display controller 400 controls the display of the first liquid crystal display panel 100 and the second liquid crystal display panel 200. Note that in this specification, for ease of understanding, Figure 1 In the liquid crystal display device 10, the right direction (right direction on paper) is referred to as the “+X direction”, the upper direction (upper direction on paper) is represented as the “+Y direction”, and the direction perpendicular to the +X direction and the +Y direction (forward direction on paper) is referred to as the “+Z direction”.
[0050] Panel section
[0051] The panel section 50 includes a first liquid crystal display panel 100 and a second liquid crystal display panel 200. The first liquid crystal display panel 100 is positioned on the observer side (+Z side) and displays color display elements. The second liquid crystal display panel 200 is positioned on the side of the first liquid crystal display panel 100 opposite to the observer side surface (the rear surface side of the first liquid crystal display panel 100) and overlaps with the first liquid crystal display panel 100. The second liquid crystal display panel 200 displays monochrome display elements.
[0052] First liquid crystal display panel
[0053] In one example, the first liquid crystal display panel 100 is implemented as a known transmissive horizontal electric field type liquid crystal display panel. The first liquid crystal display panel 100 is an active matrix driven by a thin film transistor (TFT) element.
[0054] like Figure 2 As shown, the first liquid crystal display panel 100 includes first main pixels 102 arranged in a matrix form. The first main pixel 102 includes a red pixel 104R emitting red light, a green pixel 104G emitting green light, and a blue pixel 104B emitting blue light, which are defined by a black matrix BM. Note that the red pixel 104R, the green pixel 104G, and the blue pixel 104B may be collectively referred to as "sub-pixels 104".
[0055] like Figure 3 As shown, the first liquid crystal display panel 100 includes a first TFT substrate 110, a first counter substrate 120, a first liquid crystal 130, a first polarizing plate 132, a second polarizing plate 134, and a first driving circuit 136. The first TFT substrate 110 and the first counter substrate 120 sandwich the first liquid crystal 130. The first polarizing plate 132 is provided to the first TFT substrate 110. The second polarizing plate 134 is provided to the first counter substrate 120.
[0056] In one example, the first TFT substrate 110 is implemented as a glass substrate. On the main surface 110a of the first liquid crystal 130 side of the first TFT substrate 110, a TFT element for selecting the sub-pixel 104, a common electrode, a pixel electrode, and an alignment film for aligning the first liquid crystal 130 (all not shown in the drawings) are provided.
[0057] In addition, a plurality of common wirings, a plurality of signal wirings, and a plurality of scanning wirings (none of which is shown in the figure) are formed on the main surface 110a of the first TFT substrate 110. The common wiring supplies a common potential to the common electrode, and the common electrode applies a voltage to the first liquid crystal 130. The signal wiring supplies a voltage to the pixel electrode via the TFT element, and the pixel electrode applies a voltage to the first liquid crystal 130. The signal wiring extends in the Y direction and bends along the shape of the sub-pixel 104. The scanning wiring supplies a voltage for operating the TFT element. The scanning wiring extends in a straight line in the Y direction. The sub-pixel 104 is surrounded by the signal wiring and the scanning wiring. The TFT element is arranged at the intersection of the scanning wiring and the signal wiring. The first polarizer 132 is arranged on the main surface 110b of the first TFT substrate 110 on the side opposite to the main surface 110a.
[0058] like Figure 3 As shown, the first counter substrate 120 is opposite to the first TFT substrate 110 and adhered to the first TFT substrate 110 by a sealing material 138. In one example, the first counter substrate 120 is implemented as a glass substrate. A color filter 122, a black matrix BM, an alignment film for aligning the first liquid crystal 130, and the like are arranged on the main surface 120a of the first counter substrate 120 on the first liquid crystal 130 side. In one example, the color filter 122 is implemented as a striped color filter, in which color filters of the same color are arranged in the Y direction (wherein the striped direction is the color filter in the Y direction). The red color filter, the green color filter, and the blue color filter of the color filter 122 are all surrounded by the black matrix BM, and correspond to the red pixel 104R, the green pixel 104G, and the blue pixel 104B, respectively. As shown in FIG. Figure 2 As shown, the black matrix BM defines each first main pixel 102 and each sub-pixel 104. The second polarizing plate 134 is disposed on the main surface 120b of the first counter substrate 120 opposite to the main surface 120a. Note that for ease of understanding, Figure 3 The black matrix BM, alignment film and the like are omitted.
[0059] like Figure 3 As shown, the first liquid crystal 130 is sandwiched between the first TFT substrate 110 and the first counter substrate 120. In one example, the first liquid crystal 130 is implemented as a positive nematic liquid crystal. The first liquid crystal 130 is aligned in a direction parallel to the main surface 110a of the first TFT substrate 110 by the alignment film. In addition, due to the applied voltage, the first liquid crystal 130 rotates in a plane parallel to the main surface 110a of the first TFT substrate 110.
[0060] The first polarizing plate 132 is disposed on the main surface 110b of the first TFT substrate 110. The second polarizing plate 134 is disposed on the main surface 120b of the first counter substrate 120. Either of the transmission axis of the first polarizing plate 132 and the transmission axis of the second polarizing plate 134 is arranged to be parallel to the alignment direction of the first liquid crystal 130, and the transmission axis of the first polarizing plate 132 and the transmission axis of the second polarizing plate 134 are orthogonal to each other. The first polarizing plate 132 is adhered to the second counter substrate 220 described below of the second liquid crystal display panel 200 by a light-transmitting adhesive layer 150. In one example, the adhesive layer 150 is implemented as an optically clear adhesive (OCA).
[0061] The first drive circuit 136 is provided on the main surface 110a of the first TFT substrate 110. The first drive circuit 136 supplies voltages to the scan wirings, the signal wirings, and the common wirings based on the color signals supplied from the display controller 400.
[0062] Second liquid crystal display panel
[0063] like Figure 3 As shown, the second liquid crystal display panel 200 is positioned at the back side (-Z side) of the first liquid crystal display panel 100. The second liquid crystal display panel 200 is attached to the first liquid crystal display panel 100 through an adhesive layer 150. The second liquid crystal display panel 200 displays a monochrome display element.
[0064] In this embodiment, the second liquid crystal display panel 200 is implemented as a transmissive horizontal electric field type liquid crystal display panel using positive nematic liquid crystal. The second liquid crystal display panel 200 is an active matrix driven by a switching element 240 described below. Figure 4 As shown, the second liquid crystal display panel 200 includes second main pixels 202 arranged in a matrix. In this embodiment, one second main pixel 202 of the second liquid crystal display panel 200 corresponds to 16 (4×4) first main pixels 102 of the first liquid crystal display panel 100. One second main pixel 202 of the second liquid crystal display panel 200 emits light on the 16 first main pixels 102 of the first liquid crystal display panel 100. Note that Figure 4 In the drawings referred to below, the scan wiring GL and the signal wiring DL may be shown as a dotted line or a solid line.
[0065] like Figure 3As shown, the second liquid crystal display panel 200 includes a second TFT substrate 210, a second counter substrate 220, a second liquid crystal 230, a third polarizing plate 232, and a second driving circuit 236. The second TFT substrate 210 and the second counter substrate 220 sandwich the second liquid crystal 230. The third polarizing plate 232 is disposed on the second TFT substrate 210. In this embodiment, the first polarizing plate 132 of the first liquid crystal display panel 100 is also used as a polarizing plate of the second liquid crystal display panel 200 on the light emitting side.
[0066] In one example, the second TFT substrate 210 is implemented as a glass substrate. A plurality of scan wirings GL are formed on the main surface 210a on the second liquid crystal 230 side of the second TFT substrate 210; a plurality of signal wirings DL; a common wiring (not shown); a switching element 240, a pixel electrode 250 and a common electrode CE of the second main pixel 202; an alignment film (not shown) for aligning the second liquid crystal 230; and the like (all described later). The common wiring supplies a common potential to the common electrode CE, and the common electrode CE applies a voltage to the second liquid crystal 230. The signal wiring DL supplies a voltage to the pixel electrode 250 via the switch element 240, and the pixel electrode 250 applies a voltage to the second liquid crystal 230. The scan wiring GL supplies a voltage for operating the switch element 240. The third polarizing plate 232 is disposed on the main surface 210b on the side opposite to the main surface 210a of the second TFT substrate 210.
[0067] In the present embodiment, the scanning wiring GL forms a first light-blocking pattern 260 described below. The signal wiring DL forms a second light-blocking pattern 270 described below. As described below, the switching element 240 has a light-blocking property. In addition, the end of the drain 248 of the switching element 240 connected to the pixel electrode 250 forms a light shielding member 280. The configuration of the scanning wiring GL, the signal wiring DL, the second main pixel 202 (the switching element 240, the pixel electrode 250, etc.), and the like will be described later.
[0068] The second counter substrate 220 is opposite to the second TFT substrate 210 and adhered to the second TFT substrate 210 through the sealing material 238. In one example, the second counter substrate 220 is implemented as a glass substrate. An alignment film (not shown) for aligning the second liquid crystal 230 is provided on the main surface 220a of the second liquid crystal 220 side of the second counter substrate 230. The adhesive layer 150 is provided on the main surface 220b of the second counter substrate 220 on the side opposite to the main surface 220a. The second counter substrate 220 is adhered to the first liquid crystal display panel 100 (first polarizing plate 132) via the adhesive layer 150.
[0069] The second liquid crystal 230 is sandwiched between the second TFT substrate 210 and the second counter substrate 220. In one example, the second liquid crystal 230 is implemented as a positive nematic liquid crystal. The second liquid crystal 230 is initially aligned in the Y direction by the alignment film. Due to the applied voltage, the second liquid crystal 230 rotates in a plane parallel to the main surface 210a of the second TFT substrate 210.
[0070] The third polarizing plate 232 is disposed on the main surface 210b of the second TFT substrate 210. The transmission axis of the third polarizing plate 232 is arranged to be parallel to the alignment direction of the second liquid crystal 230. Note that the transmission axis of the third polarizing plate 232 and the transmission axis of the first polarizing plate 132 (the polarizing plate on the light emitting side of the second liquid crystal display panel 200) of the first liquid crystal display panel 100 are orthogonal to each other. The second liquid crystal display panel 200 operates in a normally black mode.
[0071] The second drive circuit 236 is provided on the main surface 210a of the second TFT substrate 210. The second drive circuit 236 supplies voltages to the scanning wiring GL, the signal wiring DL, and the common wiring based on the monochrome signal supplied from the display controller 400.
[0072] Next, refer to Figure 4 and Figure 5 The scan wiring GL, the signal wiring DL, the first light-blocking pattern 260, and the second light-blocking pattern 270 are described.
[0073] The scanning wiring GL and the first light blocking pattern 260 are described. The scanning wiring GL has a light blocking property. The scanning wiring GL is formed of a metal (aluminum (Al), molybdenum (Mo), or the like). Figure 4 and Figure 5 As shown, the scanning wiring GL extends in the X direction and is arranged in the Y direction. In addition, a pair of scanning wirings GL adjacent to each other form a first light blocking pattern 260 extending in the X direction and having a light blocking property. The first light blocking pattern 260 is repeatedly arranged in the Y direction. Here, the term "light blocking property" means blocking at least a portion of incident light. In addition, in the present embodiment, the X direction corresponds to a predetermined first direction.
[0074] like Figure 5 As shown, one scanning wiring GL (hereinafter also referred to as "first blocking line 262") in a pair of scanning wirings GL adjacent to each other includes a first inclined portion 262a, a second inclined portion 262b and a first flat portion 262c. The first inclined portion 262a is inclined at an acute angle in the counterclockwise direction relative to the +X direction. The second inclined portion 262b is inclined at an acute angle in the direction opposite to the first inclined portion 262a (clockwise direction) relative to the +X direction. The first flat portion 262c extends parallel to the X direction and connects the first inclined portion 262a and the second inclined portion 262b to each other.
[0075] The other scanning wiring GL (hereinafter also referred to as "second blocking line 264") in a pair of scanning wirings GL adjacent to each other is line-symmetrical with one scanning wiring GL (first blocking line 262) with respect to the X direction. The second blocking line 264 includes a third inclined portion 264a, a fourth inclined portion 264b, and a second flat portion 264c. The third inclined portion 264a is opposite to the first inclined portion 262a of the first blocking line 262, and is inclined at an acute angle in the clockwise direction relative to the +X direction. The fourth inclined portion 264b is opposite to the second inclined portion 262b of the first blocking line 262, and is inclined at an acute angle in the direction opposite to the third inclined portion 264a (counterclockwise direction) relative to the +X direction. The second flat portion 264c extends parallel to the X direction, is opposite to the first flat portion 262c of the first blocking line 262, and connects the third inclined portion 264a and the fourth inclined portion 264b to each other.
[0076] In this embodiment, the first blocking line 262 includes a first inclined portion 262a and a second inclined portion 262b inclined in a direction opposite to the first inclined portion 262a. In addition, the first blocking line 262 and the second blocking line 264 are line-symmetrical with respect to the X direction. Figure 5 As shown, the spacing (spacing L1) between the first blocking line 262 and the second blocking line 264 varies continuously along the X direction between the first inclined portion 262a of the first blocking line 262 and the third inclined portion 264a of the second blocking line 264. In addition, the spacing (spacing L2) between the first blocking line 262 and the second blocking line 264 also varies continuously along the X direction between the second inclined portion 262b of the first blocking line 262 and the fourth inclined portion 264b of the second blocking line 264. In addition, the spacing (spacing L3 and spacing L4) between the first flat portion 262c of the first blocking line 262 and the second flat portion 264c of the second blocking line 264 varies along the Y direction. Due to these configurations, even when the second liquid crystal display panel 200 and the first liquid crystal display panel 100 overlap, the spatial frequency interference between the second liquid crystal display panel 200 and the first liquid crystal display panel 100 can be suppressed, so that the moiré of the liquid crystal display device 10 can be suppressed.
[0077] Next, the signal wiring DL and the second light blocking pattern 270 are described. Like the scanning wiring GL, the signal wiring DL has a light blocking property. The signal wiring DL is formed of a metal (aluminum (Al), molybdenum (Mo), or the like). Figure 4 and Figure 5As shown, the signal wirings DL extend in the Y direction and are arranged in the X direction. In addition, a pair of signal wirings DL adjacent to each other form a second light blocking pattern 270 extending in the Y direction and having a light blocking property. In this embodiment, the Y direction corresponds to a predetermined second direction.
[0078] like Figure 5 As shown, one of the pair of signal wirings DL adjacent to each other (hereinafter also referred to as "third blocking line 272") includes a fifth inclined portion 272a and a sixth inclined portion 272b. The fifth inclined portion 272a is inclined at an acute angle in the counterclockwise direction relative to the +Y direction. The sixth inclined portion 272b is inclined at an acute angle in the direction opposite to the fifth inclined portion 272a (clockwise direction) relative to the +Y direction.
[0079] The other signal wiring DL (hereinafter also referred to as "the fourth blocking line 274") of a pair of signal wirings DL adjacent to each other is line-symmetrical with respect to the Y direction with respect to one signal wiring DL (the third blocking line 272). The fourth blocking line 274 includes a seventh inclined portion 274a and an eighth inclined portion 274b. The seventh inclined portion 274a is opposite to the fifth inclined portion 272a of the third blocking line 272, and is inclined at an acute angle in the clockwise direction relative to the +Y direction. The eighth inclined portion 274b is opposite to the sixth inclined portion 272b of the third blocking line 272, and is inclined at an acute angle in the direction opposite to the seventh inclined portion 274a (counterclockwise direction) relative to the +Y direction.
[0080] In this embodiment, the third blocking line 272 includes a fifth inclined portion 272a and a sixth inclined portion 272b inclined in a direction opposite to the fifth inclined portion 272. In addition, the third blocking line 272 and the fourth blocking line 274 are line-symmetrical with respect to the Y direction. Figure 5 As shown, the interval L5 between the third blocking line 272 and the fourth blocking line 274 changes continuously. Due to these configurations, even when the second liquid crystal display panel 200 and the first liquid crystal display panel 100 overlap, the spatial frequency interference between the second liquid crystal display panel 200 and the first liquid crystal display panel 100 can be suppressed, so that the moiré pattern of the liquid crystal display device 10 can be suppressed.
[0081] Next, refer to Figures 6 to 11 The scan wiring GL (the first blocking line 262 and the second blocking line 264 ), the signal wiring DL (the third blocking line 272 and the fourth blocking line 274 ), and the second main pixel 202 are described. Figure 6 The scanning wiring GL and the signal wiring DL corresponding to one second main pixel 202, the switching element 240 and the contact holes CH1 and CH2 of the second main pixel 202, and the light shielding member 280 are shown. Figure 6As shown, the second primary pixel 202 has a substantially rectangular shape. The second primary pixel 202 is divided into eight regions 202A of two rows and four columns in the X direction and the Y direction. Figure 6 In the figure, for ease of understanding, the switch element 240, the contact holes CH1, CH2 and the light shielding member 280 are shown by solid lines and are shown in a simplified manner. For convenience, the contact holes CH1, CH2 and the light shielding member 280 are shown as rectangles, but the shapes of the contact holes CH1 and CH2 and the light shielding member 280 are not limited to rectangles. The switch element 240, the contact hole CH2, the light shielding member 280 and the like are sometimes also shown in a simplified manner in the following figures.
[0082] Figure 7 Two regions 200A of the eight regions 202A of the second primary pixel 202 are shown. Figure 7 As shown, two pixel electrodes 250 are arranged in each region 202A. The two pixel electrodes 250 arranged in one region 202A are connected to one switching element 240. One second main pixel 202 (16 pixel electrodes 250) is driven by a voltage (signal) from a pair of adjacent scanning wirings GL and a pair of adjacent signal wirings DL. That is, the same gate signal and the same data signal are simultaneously input to each of the eight switching elements 240. Note that the pair of adjacent scanning wirings GL can be implemented as two scanning wirings GL branched from one scanning wiring. The pair of adjacent signal wirings DL can be implemented as two signal wirings DL branched from one signal wiring. Note that for ease of understanding, Figure 7 The common electrode CE is omitted in FIG. In some of the following drawings, the common electrode CE may also be omitted.
[0083] One second main pixel 202 includes eight switching elements 240, 16 pixel electrodes 250, 16 contact holes CH1, CH2 and a common electrode CE. The switching elements 240 and contact holes CH1, CH2 of the second main pixel 202 and the scanning wiring GL and signal wiring DL corresponding to one second main pixel 202 are line symmetrical with respect to the X direction and the Y direction.
[0084] like Fig. 9 As shown, the scanning wiring GL (first blocking line 262 and second blocking line 264) is formed on the main surface 210a of the second TFT substrate 210 and is covered by the first insulating layer 292. The signal wiring DL (third blocking line 272 and fourth blocking line 274) is formed on the first insulating layer 292 and is covered by the second insulating layer 294 described below.
[0085] like Figures 8 to 10As shown, the common electrode CE of the second main pixel 202 is formed on the second insulating layer 294 . In one example, the common electrode CE is formed of indium tin oxide (ITO). The common electrode CE is covered by the third insulating layer 296 .
[0086] like Figure 7 As shown, each pixel electrode 250 of the second primary pixel 202 has a comb-tooth shape. Two pixel electrodes 250 are arranged in one region 202A. The two pixel electrodes 250 arranged in one region 202A are connected to one switching element 240 (drain 248). Figures 8 to 10 As shown, the pixel electrode 250 is formed on the third insulating layer 296. In one example, the pixel electrode 250 is formed of ITO. The pixel electrode 250 and the common electrode CE provide an auxiliary capacitor for maintaining a signal voltage applied to the second liquid crystal 230.
[0087] like Figure 6 and Figure 7 As shown, the switch element 240 of the second main pixel 202 is arranged along the scan wiring GL (the first blocking line 262 and the second blocking line 264). In the present embodiment, the two switch elements 240 are arranged at the intersection P1 of the scan wiring GL and the signal wiring DL. In other words, the two switch elements 240 are arranged along the first inclined portion 262a and the second inclined portion 262b of the first blocking line 262 and the third inclined portion 264a and the fourth inclined portion 264b of the second blocking line 264, passing through the intersection P1 of the first light-blocking pattern 260 (the first blocking line 262 and the second blocking line 264) and the second light-blocking pattern 270 (the third blocking line 272 and the fourth blocking line 274).
[0088] The switch element 240 has a light blocking property. In the present embodiment, each switch element 240 also functions as a light shielding member that shields light emitted from the backlight 300 and incident on the sub-pixel 104 (first main pixel 102 ) of the first liquid crystal display panel 100 .
[0089] like Figure 8 and Fig.11 As shown, each switching element 240 includes a gate 242, a semiconductor layer 244, a source 246, and a drain 248. The gate 242, the source 246, and the drain 248 are formed of a metal having a light blocking property, such as aluminum (Al), molybdenum (Mo), or the like. In one example, the semiconductor layer 244 is formed of amorphous silicon. In one example, the switching element 240 is implemented as a TFT element. Note that Fig.11 The first insulating layer 292 is omitted.
[0090] The gate electrode 242 is integrally formed with the scanning wiring GL on the main surface 210a of the second TFT substrate 210. Like the scanning wiring GL, the gate electrode 242 is covered by the first insulating layer 292. Since the gate electrode 242 formed on the same layer as the scanning wiring GL (the first blocking line 262 and the second blocking line 264) is formed of a metal having a light-blocking property, the switching element 240 has a light-blocking property and also functions as a light shielding member.
[0091] The semiconductor layer 244 is provided in an island-like manner over the gate electrode 242 via the first insulating layer 292. The source electrode 246 is formed integrally with the signal wiring DL.
[0092] The drain electrode 248 branches into two drain electrodes 248. Each branch drain electrode 248 is connected to the pixel electrode 250 ( Figure 7 , Fig. 9 and Fig.10 Since the contact portion 248a of the drain electrode 248 is connected to the pixel electrode 250 formed of ITO having a light-transmitting property via the contact hole CH1 or the contact hole CH2 penetrating the third insulating layer 296 and the second insulating layer 294, the contact portion 248a functions as a light shielding member for shielding light.
[0093] When viewed from above, the contact portion 248a of the drain electrode 248 connected to one pixel electrode 250 via the contact hole CH1 is positioned above the scanning wiring GL ( Figure 6 , Figure 7 and Fig. 9 ). The contact portion 248a of the drain electrode 248 connected to the other pixel electrode 250 via the contact hole CH2 is located between the intersection line CL in the region S1 and the symmetry axis SL of the scanning wiring GL, the intersection line CL connects the intersection point P1 of the scanning wiring GL and the signal wiring DL and extends in the first direction, and the region S1 is a region surrounded by the scanning wiring GL and the signal wiring DL, and wherein the interval L between the pair of scanning wirings GL is continuously widened from both ends of the region S1 along the X direction ( Figure 6 In other words, the contact portion 248a connected to the other pixel electrode 250 via the contact hole CH2 is located between the intersection line CL in the region S1 and the symmetry axis SL of the first light-blocking pattern 260, the intersection line CL connects the intersection point P1 of the first light-blocking pattern 260 and the second light-blocking pattern 270 and extends in the X direction, and the region S1 is a region surrounded by the first light-blocking pattern 260 (the first light-blocking line 262 and the second light-blocking line 264) and the second light-blocking pattern 270 (the third light-blocking line 272 and the fourth light-blocking line 274), and wherein the interval L between the first light-blocking line 262 and the second light-blocking line 264 continuously widens from both ends of the region S1 along the X direction.
[0094] In the present embodiment, since the contact portion 248a of the drain electrode 248 connected to one pixel electrode 250 via the contact hole CH1 is positioned above the scanning wiring GL, that is, above the first blocking line 262 or the second blocking line 264, the contact portion 248a does not substantially function as a light shielding member. On the contrary, the contact portion 248a of the drain electrode 248 connected to another pixel electrode 250 via the contact hole CH2 functions as a light shielding member for shielding light, and forms a light shielding member 280. The light shielding member 280 shields light emitted from the backlight 300 and incident on the sub-pixel 104 (first main pixel 102) of the first liquid crystal display panel 100.
[0095] Therefore, if Figure 6 As shown, the light shielding member 280 corresponding to one switching element 240 is located between the intersection line CL in the region S1 and the symmetry axis SL of the first light blocking pattern 260, the intersection line CL connects the intersection point P1 of the first light blocking pattern 260 and the second light blocking pattern 270 and extends in the X direction, and the region S1 is a region surrounded by the first light blocking pattern 260 (the first blocking line 262 and the second blocking line 264) and the second light blocking pattern 270 (the third blocking line 272 and the fourth blocking line 274), and wherein the spacing L between the first blocking line 262 and the second blocking line 264 is continuously widened from both ends of the region S1 along the X direction. In the region S1, two light shielding members 280 are aligned along the X direction between the intersection line CL and the symmetry axis SL in the region S1, and four light shielding members 280 are located in the region S1. The four light shielding members 280 are located at positions that are line-symmetrical with respect to the X direction and the Y direction.
[0096] like Figures 8 to 10 As shown, the first insulating layer 292 covers the scan wiring GL and the gate electrode 242 of the switch element 240. The second insulating layer 294 covers the semiconductor layer 244, the source electrode 246 and the drain electrode 248 of the switch element 240 and the first insulating layer 292. The third insulating layer 296 covers the common electrode CE and the second insulating layer 294. The first insulating layer 292, the second insulating layer 294 and the third insulating layer 296 are made of silicon nitride (SiN x ), silicon oxide (SiO x ) and similar materials.
[0097] In this embodiment, one second main pixel 202 corresponds to 16 (4×4) first main pixels 102 of the first liquid crystal display panel 100. Figure 6As shown, the switching elements 240 having a light-blocking property are aligned with wide spacing therebetween in the X direction and the Y direction. Therefore, if the light emitted from the backlight 300 and incident on the sub-pixel 104 of the first liquid crystal display panel 100 is blocked only by the switching elements 240, the spacing between the dark areas caused by the switching elements 240 will become wider, and the dark areas caused by the switching elements 240 may be recognized by the observer as display inconsistency.
[0098] In the present embodiment, the light shielding member 280 is located between the intersection line CL and the symmetry axis SL within the region S1, and shields the light emitted from the backlight 300 and incident on the sub-pixel 104 of the first liquid crystal display panel 100. As a result, a dark area is formed due to each of the switching element 240 and the light shielding member 280, and the spacing between the dark areas is narrowed. This suppresses the observer from perceiving the dark area as display inconsistency. That is, the display inconsistency caused by the dark area can be suppressed.
[0099] Next, the arrangement of the first light blocking pattern 260 (scanning wiring GL), the second light blocking pattern 270 (signal wiring DL), the switching element 240 and the light shielding member 280 overlapping with the sub-pixel 104 of the first liquid crystal display panel 100 is described.
[0100] like Fig.12 As shown, in the first light-blocking pattern 260, the first inclined portion 262a and the second inclined portion 262b of the first blocking line 262 and the third inclined portion 264a and the fourth inclined portion 264b of the second blocking line 264 obliquely pass through a plurality of sub-pixels 104 (104R, 104G, 104B) of different colors of the first liquid crystal display panel 100. Therefore, the brightness of the sub-pixel 104 overlapping with the first light-blocking pattern 260 is slightly reduced, and the first main pixel 102 including the sub-pixel 104 overlapping with the first light-blocking pattern 260 presents a color slightly different from the color expected to be displayed. However, since the sub-pixels 104 with similar degrees of brightness reduction are positioned very close, the brightness of the sub-pixels 104 is averaged for an observer observing the liquid crystal display device 10, and the observer recognizes the brightness of the plurality of sub-pixels 104 with reduced brightness as the same brightness level. Therefore, with respect to the entire display of the liquid crystal display device 10, the observer's recognition of color moiré can be suppressed.
[0101] In the second light-blocking pattern 270, the fifth inclined portion 272a and the sixth inclined portion 272b of the third light-blocking line 272 and the seventh inclined portion 274a and the eighth inclined portion 274b of the fourth light-blocking line 274 obliquely pass through a plurality of sub-pixels 104 (104R, 104B) of different colors of the first liquid crystal display panel 100. Therefore, as with the first light-blocking pattern 260, the first main pixel 102 including the sub-pixel 104 overlapping the second light-blocking pattern 270 presents a color slightly different from the color to be displayed as expected. However, the color presented by the first main pixel 102 including the sub-pixel 104 overlapping the second light-blocking pattern 270 and the color presented by the first main pixel 102 located near the first main pixel 102 including the sub-pixel 104 overlapping the second light-blocking pattern 270 are recognized by the observer as different colors, and the saturation of the mixed color is also reduced. Therefore, with respect to the entire display of the liquid crystal display device 10, the observer's recognition of color moiré can be suppressed.
[0102] The switch element 240 and the light shielding member 280 overlap a portion of the sub-pixel 104. Fig.12 As shown, it is preferred that the light shielding member 280 is located on a straight line PL1 connecting one end of the first flat portion 262c and one end of the second flat portion 264c and extending in the Y direction, or is located on a straight line PL2 connecting the other end of the first flat portion 262c and the other end of the second flat portion 264c and extending in the Y direction. Preferably, the center P2 of the light shielding member 280 is located in the Y direction away from the center line PL3 extending in the X direction of the first flat portion 262c or the second flat portion 264c, and has a space corresponding to one of the sub-pixels (the length D1 of the sub-pixel 104 in the Y direction). In addition, it is preferred that the space in the X direction between the centers P2 of the two light shielding members 280 aligned in the X direction is an amount corresponding to one of the sub-pixels (the length D2 of the sub-pixel 104 in the X direction). Such a configuration makes it possible to suppress display inconsistency caused by dark areas.
[0103] Backlight
[0104] like Figure 1 and Figure 3 As shown, the backlight 300 is arranged on the rear side surface (-Z side) of the second liquid crystal display panel 200. In one example, the backlight 300 is implemented as a direct-type backlight. The backlight 300 includes a white light emitting diode (LED), a reflective sheet, a diffusion sheet, and the like (all not shown in the drawings).
[0105] The display controller 400 controls the display of the first liquid crystal display panel 100 and the second liquid crystal display panel 200. Fig.13As shown, the display controller 400 includes an image data distributor 410 , a first image signal generator 420 , a second image brightness signal generator 430 , and a second image signal generator 440 .
[0106] The image data distributor 410 distributes input image data to the first image signal generator 420 and the second image brightness signal generator 430 .
[0107] The first image signal generator 420 generates a color display element to be displayed on the first liquid crystal display panel 100 according to the input image data distributed by the image data distributor 410. Specifically, the first grayscale converter 422 of the first image signal generator 420 performs grayscale conversion for converting the distributed input image data into color data having a brightness-grayscale characteristic suitable for the first liquid crystal display panel 100. In one example, a lookup table in which an input / output relationship is preset is used in the conversion of data. The first image signal generator 420 sends a color signal representing the generated color display element to the first driving circuit 136 of the first liquid crystal display panel 100.
[0108] The second image brightness signal generator 430 generates a brightness signal according to the input image data distributed by the image data distributor 410, for generating a monochrome display element to be displayed on the second liquid crystal display panel 200. In one example, the second image brightness signal generator 430 calculates the brightness level of one second main pixel 202 of the second liquid crystal display panel 200 according to the average value, frequency value, minimum value, maximum value and the like of the red grayscale value, green grayscale value and blue grayscale value of the 16 first main pixels 102 of the first liquid crystal display panel 100 into which light emitted from one second main pixel 202 of the second liquid crystal display panel 200 enters. The calculated brightness level may be a grayscale value. The second image brightness signal generator 430 sends a brightness signal indicating the calculated brightness level to the second image signal generator 440.
[0109] The second image signal generator 440 generates a monochrome display element to be displayed on the second liquid crystal display panel 200 based on the brightness signal sent from the second image brightness signal generator 430. In one example, the second image signal generator 440 generates a monochrome display element that has been averaged and grayscale converted. Specifically, in one example, the calculator 442 of the second image signal generator 440 averages the brightness level of the second main pixel 202 located within a predetermined distance from the target second main pixel 202 using a weighted average value based on the distance from the target second main pixel 202. Therefore, the second image signal generator 440 can generate a monochrome display element with a blurred edge. In addition, the second grayscale converter 444 of the second image signal generator 440 generates monochrome data having a brightness-grayscale characteristic suitable for the second liquid crystal display panel 200. The configuration of the second grayscale converter 444 is the same as that of the first grayscale converter 422 of the first image signal generator 420. The second grayscale converter 444 sends a monochrome signal representing the generated monochrome display element to the second driving circuit 236 of the second liquid crystal display panel 200.
[0110] By the calculation of the brightness level, the averaging process, and the like performed by the second image brightness signal generator 430, the monochrome signal sent to the second liquid crystal display panel 200 is delayed relative to the color signal sent to the first liquid crystal display panel 100. Therefore, the display controller 400 includes a not-shown synchronization circuit for synchronizing the output of the monochrome signal and the color signal. Due to the synchronization circuit, the monochrome display element corresponding to the color display element of the first liquid crystal display panel 100 is displayed on the second liquid crystal display panel 200, and therefore, the appropriate color display element is displayed on the liquid crystal display device 10.
[0111] The display controller 400 is configured by a graphics processing unit (GPU), a memory, a timing controller, a power supply circuit, and the like. In one example, the GPU processes input data stored in the memory, and the timing controller generates signals corresponding to the first liquid crystal display panel 100 and the second liquid crystal display panel 200 based on the processed data to implement the functions of the display controller 400.
[0112] As described above, the first light-blocking pattern 260 (scanning wiring GL) of the second liquid crystal display panel 200 is formed by a first light-blocking line 262 and a second light-blocking line 264, the first light-blocking line 262 includes a first inclined portion 262a, a second inclined portion 262b, and a first flat portion 262c connecting the first inclined portion 262b and the second inclined portion 262a to each other, and the second light-blocking line 264 is line-symmetrical with the first light-blocking line with respect to the X direction. Therefore, spatial frequency interference in the first liquid crystal display panel 100 and the second liquid crystal display panel 200 can be suppressed, and therefore, moiré of the liquid crystal display device 10 can be suppressed. In addition, the occurrence of color moiré can also be suppressed.
[0113] In addition, the second light-blocking pattern 270 (signal wiring DL) of the second liquid crystal display panel 200 is formed by a third light-blocking line 272 including a fifth inclined portion 272a and a sixth inclined portion 272b, and a fourth light-blocking line 274 that is line-symmetrical with the third light-blocking line 272 with respect to the Y direction. Therefore, spatial frequency interference in the first liquid crystal display panel 100 and the second liquid crystal display panel 200 can be suppressed, and therefore, moiré of the liquid crystal display device 10 can be suppressed. In addition, the occurrence of color moiré can also be suppressed.
[0114] In addition, the light shielding member 280 is located between the intersection line CL and the symmetry axis SL of the first light blocking pattern 260 in the region S1, the intersection line CL connects the intersection point P1 of the first light blocking pattern 260 and the second light blocking pattern 270 and extends in the X direction, and the region S1 is a region surrounded by the first light blocking pattern 260 and the second light blocking pattern 270, wherein the spacing L between the first blocking line 262 and the second blocking line 264 is continuously widened in the X direction from both ends of the region S1. As a result, the spacing between the dark areas caused by the switching element 240 and the light shielding member 280 is narrowed, and therefore, the display inconsistency caused by the light shielding member (the switching element 240 and the light shielding member 280) can be suppressed. As a result, the liquid crystal display device 10 can suppress moiré and can also suppress the display inconsistency caused by the light shielding member.
[0115] In this embodiment, one switching element 240 is connected to two pixel electrodes 250. Therefore, even if a defect occurs in the pixel electrode 250, the defect area within the second main pixel 202 can be minimized, and the manufacturing yield of the second liquid crystal display panel 200 can be improved.
[0116] Example 2
[0117] In Embodiment 1, the light shielding member 280 of the second liquid crystal display panel 200 is formed by the contact portion 248a of the drain electrode 248. However, a configuration in which the light shielding member 280 is formed by a dummy light blocking layer is also possible.
[0118] Like the liquid crystal display device 10 of Embodiment 1, the liquid crystal display device 10 of this embodiment includes a panel portion 50, a backlight 300, and a display controller 400. The configurations of the first liquid crystal display panel 100, the first light-blocking pattern 260 and the second light-blocking pattern 270 (the scanning wiring GL and the signal wiring DL) of the second liquid crystal display panel 200, the backlight 300, the display controller 400, and the like in this embodiment are the same as those of these components in Embodiment 1. Here, the second main pixel 202 and the light shielding member 280 of the second liquid crystal display panel 200 are described.
[0119] Also in this embodiment, the second liquid crystal display panel 200 includes second main pixels 202 ( Figure 4 ). In addition, one second main pixel 202 of the second liquid crystal display panel 200 corresponds to 16 (4×4) first main pixels 102 of the first liquid crystal display panel 100 .
[0120] like Fig.14 As shown, the second primary pixel 202 of this embodiment has a rectangular shape and is divided into eight regions 202A of two rows and four columns in the X direction and the Y direction. Fig.15 As shown, one pixel electrode 250 is arranged in each region 202A. One pixel electrode 250 arranged in one region 202A is connected to one switching element 240. As in Embodiment 1, one second main pixel 202 (eight pixel electrodes 250) is driven by a voltage (signal) from a pair of adjacent scanning wirings GL and a pair of adjacent signal wirings DL.
[0121] like Fig.15 As shown, each pixel electrode 250 of the second main pixel 202 of the present embodiment has a comb-tooth shape. In the present embodiment, one pixel electrode 250 is arranged in one area 202A. One pixel electrode 250 is connected to one switching element 240 (contact portion 248a of the drain 248) via a contact hole CH1 located above the scanning wiring GL (the first blocking light 262 and the second blocking light 264). In the present embodiment, since the contact portion 248a of the drain 248 connected to one pixel electrode 250 via the contact hole CH1 is positioned above the scanning wiring GL, the contact portion 248a does not basically play the same role as the light shielding member in Embodiment 1.
[0122] As in the first embodiment, the switch element 240 of the second main pixel 202 of the present embodiment is arranged along the scanning line GL ( Fig.14 and Fig.15 ). Also in the present embodiment, two switch elements 240 are arranged across the intersection P1 of the scan wiring GL and the signal wiring DL (the third blocking line 272 and the fourth blocking line 274).
[0123] Also in this embodiment, the switch element 240 has a light-blocking property. The configuration of the switch element 240 of this embodiment is the same as that of the switch element 240 of Embodiment 1, except that the drain 248 is not branched and one drain 248 is connected to one switch element 240 via the contact hole CH1 located above the scanning wiring GL.
[0124] As with the light-blocking member 280 of the first embodiment, the light-blocking member 280 of the present embodiment is located within the region S1 between the intersection line CL and the symmetry axis SL of the first light-blocking pattern 260, the intersection line CL connects the intersection point P1 of the first light-blocking pattern 260 and the second light-blocking pattern 270 and extends in the X direction, and the region S1 is a region surrounded by the first light-blocking pattern 260 (the first light-blocking line 262 and the second light-blocking line 264) and the second light-blocking pattern 270 (the third light-blocking line 272 and the fourth light-blocking line 274), and wherein the spacing L between the first light-blocking line 262 and the second light-blocking line 264 continuously widens from both ends of the region S1 along the X direction ( Fig.14 In addition, in the region S1, two light shielding members 280 are aligned along the X direction between the intersection line CL and the symmetry axis SL, and four light shielding members 280 are located in the region S1. The four light shielding members 280 are located at positions that are line-symmetrical with respect to the X direction and the Y direction.
[0125] The light shielding member 280 of the present embodiment is formed by a virtual light blocking layer DM made of metal, organic material or the like having light blocking properties. Fig.16 As shown, the light shielding member 280 (virtual light blocking layer DM) is formed on the main surface 210 a of the second TFT substrate 210 .
[0126] The configuration of the first light-blocking pattern 260 and the second light-blocking pattern 270 (the scanning wiring GL and the signal wiring DL) and the arrangement of the switching element 240 and the light shielding member 280 in this embodiment are the same as those in Embodiment 1. Therefore, like the liquid crystal display device 10 of Embodiment 1, the liquid crystal display device 10 of this embodiment can suppress moiré and can also suppress display inconsistency caused by the light shielding member (the switching element 240 and the light shielding member 280).
[0127] Example 3
[0128] In the second liquid crystal display panel 200 of Embodiment 1, two switching elements 240 are arranged at the intersection P1 of the scan wiring GL and the signal wiring DL. The switching element 240 may be arranged at the intersection P1 of the scan wiring GL (first light blocking pattern 260) and the signal wiring DL (second light blocking pattern 270). A portion of the plurality of light shielding members 280 may be formed by the contact portion 248a of the drain electrode 248, and another portion of the plurality of light shielding members 280 may be formed from the virtual light blocking layer DM.
[0129] Like the liquid crystal display device 10 of Embodiment 1, the liquid crystal display device 10 of this embodiment includes a panel portion 50, a backlight 300, and a display controller 400. The configurations of the first liquid crystal display panel 100, the first light-blocking pattern 260 and the second light-blocking pattern 270 (the scanning wiring GL and the signal wiring DL) of the second liquid crystal display panel 200, the backlight 300, the display controller 400, and the like in this embodiment are the same as those of these components in Embodiment 1. Here, the second main pixel 202 and the light shielding member 280 of the second liquid crystal display panel 200 are described.
[0130] Also in this embodiment, the second liquid crystal display panel 200 includes second main pixels 202 arranged in a matrix. In addition, one second main pixel 202 of the second liquid crystal display panel 200 corresponds to 16 (4×4) first main pixels 102 of the first liquid crystal display panel 100 .
[0131] like Fig.17 As shown, the second primary pixel 202 of this embodiment has a rectangular shape and is divided into four regions 202A of two rows and two columns in the X direction and the Y direction. Fig.18 As shown, one pixel electrode 250 is arranged in each region 202A. One pixel electrode 250 arranged in one region 202A is connected to one switching element 240. As in Embodiment 1, one second main pixel 202 (four pixel electrodes 250) is driven by a voltage (signal) from a pair of adjacent scanning wirings GL and a pair of adjacent signal wirings DL.
[0132] like Fig.18 As shown, each pixel electrode 250 of the second main pixel 202 of the present embodiment has a comb-tooth shape. In the present embodiment, one pixel electrode 250 is arranged in one region 202A. One pixel electrode 250 is connected to one switching element 240 (drain 248) via a contact hole CH. In the present embodiment, the contact portion 248a of the drain 248 connected to one pixel electrode 250 via the contact hole CH2 forms a light shielding member 280, as in the embodiment 1.
[0133] like Fig.17 As shown, the switch element 240 of the second main pixel 202 of this embodiment is arranged at the intersection P1 of the scanning wiring GL and the signal wiring DL. In this embodiment, the switch element 240 also has a light blocking property.
[0134] Also in this embodiment, if Fig.19As shown, the gate electrode 242 of the switching element 240 is formed integrally with the scanning wiring GL. In addition, the semiconductor layer 244 of the switching element 240 is arranged in an island-like manner above the gate electrode 242 via the first insulating layer 292. The source electrode 246 of the switching element 240 is formed integrally with the signal wiring DL. The drain electrode 248 of the switching element 240 is connected to the pixel electrode 250 ( Fig.18 ). The configuration of the first insulating layer 292, the second insulating layer 294, and the like are the same as those in Embodiment 1. In addition, Fig.19 The first insulating layer 292 is omitted.
[0135] As with the light-blocking member 280 of the first embodiment, the light-blocking member 280 of the present embodiment is located within the region S1 between the intersection line CL and the symmetry axis SL of the first light-blocking pattern 260, the intersection line CL connects the intersection point P1 of the first light-blocking pattern 260 and the second light-blocking pattern 270 and extends in the X direction, the region S1 is a region surrounded by the first light-blocking pattern (the first light-blocking line 262 and the second light-blocking line 264) and the second light-blocking pattern 270 (the third light-blocking line 272 and the fourth light-blocking line 274), and wherein the spacing L between the first light-blocking line 262 and the second light-blocking line 264 is continuously widened from both ends of the region S1 along the X direction ( Fig.17 ). In addition, in the region S1, two light shielding members 280 are aligned along the X direction between the intersection line CL and the symmetry axis SL, and four light shielding members 280 are located in the region S1. The four light shielding members 280 are located at positions that are line-symmetrical with respect to the X direction and the Y direction. In the present embodiment, one of the two light shielding members 280 arranged in the X direction is formed by the contact portion 248a of the drain 248, and the drain 248 is connected to one pixel electrode 250 via the contact hole CH. Like the light shielding member 280 of Embodiment 2, the other of the two light shielding members 280 arranged in the X direction is formed by a virtual light blocking layer DM.
[0136] The configuration of the first light-blocking pattern 260 and the second light-blocking pattern 270 (scanning wiring GL and signal wiring DL) of this embodiment is the same as the configuration of the first light-blocking pattern 260 and the second light-blocking pattern 270 in Example 1. Therefore, the liquid crystal display device 10 of this embodiment can also suppress color moiré. In this embodiment, the switching element 240 is arranged at the intersection P1 of the scanning wiring GL and the signal wiring DL, and the shading member 280 is located in the area S1 between the intersection line CL and the symmetry axis SL. Therefore, the spacing between the dark areas formed by the shading member (switching element 240 and shading member 280) is narrowed. Therefore, the liquid crystal display device 10 of this embodiment can also suppress the display inconsistency caused by the dark area. As described above, like the liquid crystal display device 10 of Example 1, the liquid crystal display device 10 of this embodiment can suppress moiré, and can also suppress the display inconsistency caused by the shading member (switching element 240 and shading member 280).
[0137] Example 4
[0138] In Embodiment 3, the switching element 240 is arranged at the intersection P1 of the scan wiring GL and the signal wiring DL, and a portion of the plurality of light shielding members 280 is formed by the contact portion 248a of the drain electrode 248. The switching element 240 may be arranged at the intersection P1 of the scan wiring GL and the signal wiring DL, and all of the plurality of light shielding members 280 may be formed by the dummy light blocking layer DM.
[0139] Here, the contact hole CH of the second main pixel 202 and the light shielding member 280 are described. The other configurations of the liquid crystal display device 10 of the present embodiment are the same as those of the third embodiment.
[0140] like Fig. 20 and 21 As shown, the contact hole CH of the present embodiment is arranged near the switching element 240. In addition, when the first liquid crystal display panel 100 overlaps with the second liquid crystal display panel 200, the contact hole of the present embodiment overlaps with the black matrix BM of the first liquid crystal display panel 100. The switching element 240 (the contact portion 248a of the drain electrode 248) of the present embodiment is connected to the pixel electrode 250 via the contact hole CH. In the present embodiment, the contact hole CH overlaps with the black matrix BM of the first liquid crystal display panel 100. Therefore, the contact portion 248a of the drain electrode 248 does not substantially function as a light shielding member that blocks light incident on the sub-pixel 104 (the first main pixel 102) of the first liquid crystal display panel 100.
[0141] All the light shielding members 280 of this embodiment are formed of a virtual light blocking layer DM. The configuration of the virtual light blocking layer DM of this embodiment is the same as that of the virtual light blocking layer in the second embodiment.
[0142] As in Embodiments 1 to 3, the light shielding member 280 of this embodiment is located in the region S1 between the intersection line CL and the symmetry axis SL of the first light-blocking pattern 260, the intersection line CL connects the intersection point P1 of the first light-blocking pattern 260 and the second light-blocking pattern 270 and extends in the X direction, and the region S1 is a region surrounded by the first light-blocking pattern 260 (the first light-blocking line 262 and the second light-blocking line 264) and the second light-blocking pattern 270 (the third light-blocking line 272 and the fourth light-blocking line 274), and wherein the spacing L between the first light-blocking line 262 and the second light-blocking line 264 continuously widens from both ends of the region S1 along the X direction ( Fig. 20 In addition, in the region S1, two light shielding members 280 are aligned along the X direction between the intersection line CL and the symmetry axis SL, and four light shielding members 280 are located in the region S1. The four light shielding members 280 are located at positions that are line-symmetrical with respect to the X direction and the Y direction.
[0143] The configuration of the first light-blocking pattern 260 and the second light-blocking pattern 270 (the scanning wiring GL and the signal wiring DL) and the arrangement of the switching element 240 and the light shielding member 280 in this embodiment are the same as those in Embodiment 3. Therefore, like the liquid crystal display device 10 of Embodiment 3, the liquid crystal display device 10 of this embodiment can suppress moiré and can also suppress display inconsistency caused by the light shielding member (the switching element 240 and the light shielding member 280).
[0144] Example 5
[0145] In Embodiment 3, the switch element 240 is arranged at the intersection P1 of the scan wiring GL and the signal wiring DL, and a portion of the plurality of light shielding members 280 is formed by the contact hole CH. The switch element 240 may be arranged at the intersection P1 of the scan wiring GL and the signal wiring DL, and all of the plurality of light shielding members 280 may be formed by the contact portion 248a of the drain electrode 248.
[0146] Like the liquid crystal display device 10 of Embodiments 1 to 4, the liquid crystal display device 10 of this embodiment includes a panel portion 50, a backlight 300, and a display controller 400. The configurations of the first liquid crystal display panel 100, the first light-blocking pattern 260 and the second light-blocking pattern 270 (scanning wiring GL and signal wiring DL) of the second liquid crystal display panel 200, the backlight 300, the display controller 400, and the like in this embodiment are the same as those of these components in Embodiments 1 to 4. Here, the second main pixel 202 of the second liquid crystal display panel 200 and the light shielding member 280 are described.
[0147] Also in this embodiment, the second liquid crystal display panel 200 includes second main pixels 202 arranged in a matrix. In addition, one second main pixel 202 of the second liquid crystal display panel 200 corresponds to 16 (4×4) first main pixels 102 of the first liquid crystal display panel 100 .
[0148] like Fig. 22 As shown, the second primary pixel 202 of this embodiment has a rectangular shape and is divided into four regions 202A of two rows and two columns in the X direction and the Y direction. Fig.23 As shown, two pixel electrodes 250 are arranged in each region 202A. The two pixel electrodes 250 arranged in one region 202A are connected to one switching element 240. As in Embodiment 1, one second main pixel 202 (eight pixel electrodes 250) is driven by a voltage (signal) from a pair of adjacent scanning wirings GL and a pair of adjacent signal wirings DL.
[0149] like Fig.23 As shown, each pixel electrode 250 of the second main pixel 202 of the present embodiment has a comb-tooth shape. In the present embodiment, two pixel electrodes 250 are arranged in one area 202A. In the present embodiment, two pixel electrodes 250 are connected to one switching element 240. The pixel electrode 250 is connected to the switching element 240 (the contact portion 248a of the drain 248) via the contact hole CH. In the present embodiment, as in Example 3, the contact portion 248a of the drain 248 connected to the pixel electrode 250 via the contact hole CH forms a light shielding member 280.
[0150] Like the switch element 240 in Embodiment 4, the switch element 240 of the second main pixel 202 of this embodiment is arranged at the intersection P1 of the scanning wiring GL and the signal wiring DL ( Fig. 22 ). The switch element 240 of this embodiment also has a light blocking property.
[0151] Also in this embodiment, if Fig.24 As shown, the gate electrode 242 of the switching element 240 is formed integrally with the scanning wiring GL. In addition, the semiconductor layer 244 of the switching element 240 is arranged in an island-like manner above the gate electrode 242 via the first insulating layer 292. The source electrode 246 of the switching element 240 is formed integrally with the signal wiring DL. The drain electrode 248 of the switching element 240 is connected to the pixel electrode 250 at the contact portion 248a via the contact hole CH. In the present embodiment, the two drain electrodes 248 are provided with the source electrode 246 therebetween, and each drain electrode 248 is connected to the corresponding pixel electrode 250 at the corresponding contact portion 248a ( Fig.23 ). The structures of the first insulating layer 292, the second insulating layer 294 and the like are the same as those in Embodiment 1. In addition, Fig.24The first insulating layer 292 is omitted.
[0152] In the present embodiment, the source 246 is disposed between the two drains 248 , and thus the size of the switching element 240 can be reduced.
[0153] All the light shielding members 280 of this embodiment are formed by the contact portion 248a of the drain electrode 248 connected to the pixel electrode 250 via the contact hole CH. The light shielding members 280 of this embodiment are different from those of Embodiments 1 to 4 ( Fig. 22 ) are arranged in the same manner as the shading member 280.
[0154] The configuration of the first light-blocking pattern 260 and the second light-blocking pattern 270 (the scanning wiring GL and the signal wiring DL) in this embodiment is the same as that of the first light-blocking pattern 260 and the second light-blocking pattern 270 in Embodiments 1 to 4. The arrangement of the switching element 240 and the light shielding member 280 in this embodiment is the same as that of the switching element 240 and the light shielding member 280 in Embodiment 4. Therefore, the liquid crystal display device 10 of this embodiment can also suppress moiré and suppress display inconsistency caused by the light shielding member (the switching element 240 and the light shielding member 280).
[0155] In addition, one switching element 240 is connected to two pixel electrodes 250. Therefore, even if a defect occurs in the pixel electrode 250, the defect area within the second main pixel 202 can be minimized, and the manufacturing yield of the second liquid crystal display panel 200 can be improved. In addition, the source electrode 246 is provided between the two drain electrodes 248, and thus the size of the switching element 240 can be reduced.
[0156] Modification example
[0157] Although the embodiments have been described above, various modifications may be made to the present disclosure without departing from the scope of the present disclosure.
[0158] For example, in the embodiment, the first liquid crystal display panel 100 and the second liquid crystal display panel 200 are operated by the horizontal electric field type method. However, the operation methods of the first liquid crystal display panel 100 and the second liquid crystal display panel 200 may be determined as needed.
[0159] In an embodiment, the first liquid crystal display panel 100 is positioned on the observer side (+Z side), and the second liquid crystal display panel 200 is positioned on the side opposite to the surface on the observer side of the first liquid crystal display panel 100. The second liquid crystal display panel 200 may be positioned on the observer side, and the first liquid crystal display panel 100 may be positioned on the side opposite to the surface on the observer side of the second liquid crystal display panel 200.
[0160] In the present embodiment, the first polarizing plate 132 of the first liquid crystal display panel 100 also serves as a polarizing plate on the light emitting side of the second liquid crystal display panel 200. However, a configuration in which the second liquid crystal display panel 200 includes a polarizing plate on the major surface 220b of the second counter substrate 220 is possible.
[0161] In this embodiment, the stripe direction of the color filter 122 of the first liquid crystal display panel 100 is the Y direction. A configuration in which the stripe direction of the color filter 122 of the first liquid crystal display panel 100 is the X direction is also possible.
[0162] In the embodiment, the second liquid crystal display panel 200 is not provided with a color filter and a black matrix, but the second liquid crystal display panel 200 may be provided with a color filter or a black matrix.
[0163] In an embodiment, the first liquid crystal display panel 100 includes a first liquid crystal 130 implemented as a positive nematic liquid crystal. The second liquid crystal display panel 200 includes a second liquid crystal 230 implemented as a positive nematic liquid crystal. The first liquid crystal 130 may be implemented as a negative nematic liquid crystal. The second liquid crystal 230 may be implemented as a negative nematic liquid crystal.
[0164] In the present embodiment, the first light-blocking line 262 of the first light-blocking pattern 260 includes a first flat portion 262c, and the second light-blocking line 264 of the first light-blocking pattern 260 includes a second flat portion 264c. However, a configuration in which the first light-blocking line 262 does not include the first flat portion 262c, and the second light-blocking line 264 does not include the second flat portion 264c is possible. That is, the first light-blocking line 262 and the second light-blocking line 264 may have a line-symmetric relationship with respect to the X direction, and each extends in a zigzag shape in the X direction.
[0165] At the same time, it is possible that the third light-blocking line 272 of the second light-blocking pattern 270 includes a third flat portion connecting the fifth inclined portion 272a and the sixth inclined portion 272b to each other and extending parallel to the Y direction. Additionally, it is possible that the fourth light-blocking line 274 of the second light-blocking pattern 270 includes a fourth flat portion connecting the seventh inclined portion 274a and the eighth inclined portion 274b to each other and extending parallel to the Y direction.
[0166] In addition, the second light-blocking pattern 270 (the third light-blocking lines 272 and the fourth light-blocking lines 274 ) may be in a linear manner.
[0167] In an embodiment, the scanning wiring GL forms the first light-blocking line 262 and the second light-blocking line 264 of the first light-blocking pattern 260. It is sufficient that at least one of the first light-blocking line 262 and the second light-blocking line 264 of the first light-blocking pattern 260 is formed by the scanning wiring GL. For example, the following configuration is possible: in the case where the first light-blocking line 262 is formed by the scanning wiring GL, the second light-blocking line 264 is a low-resistance wiring connected to the common electrode CE. A configuration in which the second light-blocking line 264 is a light-shielding member (light-blocking pattern) formed of an organic material having a light-blocking property is possible.
[0168] The second light-blocking pattern 270 does not need to be formed by the signal wiring DL. For example, a configuration in which the second light-blocking pattern 270 is a light shielding member formed of an organic material having a light-blocking property is possible. In addition, a configuration in which one of the third blocking line 272 and the fourth blocking line 274 of the second light-blocking pattern 270 is formed by the signal wiring DL, and the other is formed by an organic material having a light-blocking property is possible.
[0169] In the embodiment, the source 246 of the switch element 240 is in a straight line form, but the source 246 may have a U-shape. Fig.25 As shown, each switching element 240 in Embodiment 3 may include a U-shaped source electrode 246. Therefore, the size of the switching element 240 may be reduced. Fig.25 The first insulating layer 292 is omitted.
[0170] In this embodiment, one second main pixel 202 of the second liquid crystal display panel 200 corresponds to 16 first main pixels 102 of the first liquid crystal display panel 100. However, the number of first main pixels 102 of the first liquid crystal display panel 100 to which one second main pixel 202 of the second liquid crystal display panel 200 corresponds can be set as needed.
[0171] In the embodiment, the same gate signal (gate signal at the same timing) from a pair of adjacent scan wirings GL and the same data signal from a pair of adjacent signal wirings DL are input to the switch element 240, and thus drive one second main pixel 202 of the second liquid crystal display panel 200. A pair of adjacent scan wirings GL may supply gate signals to the switch element 240 at different timings, and may supply different data signals to the switch element 240. In this case, Embodiment 1 ( Figure 6 ) corresponds to the configuration of a second main pixel 202 of the modified example ( Fig.26 ) is configured with four (2×2) second main pixels 202 in .
[0172] Contact holes CH, CH1 , CH2 may be formed on the plurality of comb-teeth-like portions of the pixel electrode 250 .
[0173] The contact portion 248a of the drain electrode 248 forming the light shielding member 280 is positioned at the bottom of the contact holes CH, CH1, and CH2. Therefore, it can be said that the contact hole CH2 of Embodiment 1 and the contact holes CH of Embodiments 3 and 5 function as a light shielding member for shielding light.
[0174] In Embodiment 1, a contact hole CH1 and a contact portion 248a ( 248b ) of the drain electrode 248 connected to the pixel electrode 250 via the contact hole CH1 are formed above the scan wiring GL. Fig. 9 Meanwhile, the scanning wiring GL is not formed below the contact hole CH2 and the contact portion 248a of the drain electrode 248 connected to the pixel electrode 250 via the contact hole CH2. Fig.10 ). A light shielding member may be formed under the contact hole CH2 and the contact portion 248a of the drain electrode 248 connected to the pixel electrode 250 via the contact hole CH2 using the same material as the scan wiring GL. By forming the light shielding member, the cross-sectional structure of the contact hole CH1 and the cross-sectional structure of the contact hole CH2 will be the same. Therefore, the shape change of the contact hole CH1 and the contact hole CH2 and the poor connection between the pixel electrode 250 and the drain electrode 248 can be suppressed.
[0175] The wiring width of the drain electrode 248 between the contact portion 248a (light shielding member 280) connected to the pixel electrode 250 via the contact holes CH, CH2 and the switch element 240 is preferably narrower than the wiring width of the signal wiring DL and the wiring width of the scanning wiring GL. Therefore, the light blocking effect that can be achieved by the drain electrode 248 between the contact portion 248a and the switch element 240 is smaller than the light blocking effect that can be achieved by the contact portion 248a (light shielding member 280). However, by adjusting the wiring width of the drain electrode 248 between the contact portion 248a and the switch element 240, the entire drain electrode 248 can function as a light shielding member.
[0176] In the embodiment, the virtual light blocking layer DM (light shielding member 280) is formed above the main surface 210a of the second TFT substrate 210. However, the position where the virtual light blocking layer DM is formed can be determined as needed. For example, a configuration in which the virtual light blocking layer DM is formed above the first insulating layer 292 is possible. In addition, a configuration in which the virtual light blocking layer DM is provided to the second counter substrate 220 is possible.
[0177] Preferably, a portion of the boundary BL between two adjacent pixel electrodes 250 is along the scan wiring GL (first light-blocking pattern 260) or the signal wiring DL (second light-blocking pattern 270). Fig. 27 As shown, a portion of the boundary BL of the pixel electrode 250 in Embodiment 1 may overlap with the scanning wiring GL or the signal wiring DL. Note that, for ease of understanding, Fig. 27The drain electrode 248, contact holes CH1, CH2, and the like are omitted.
[0178] The switching element 240 of the second main pixel 202 may be arranged along the scan wiring GL (the first blocking line 262 and the second blocking line 264). In the embodiment, the switching element 240 is inclined with respect to the X direction, but the switching element 240 may be formed along the X direction.
[0179] Some example embodiments have been described above for the purpose of illustration. Although the foregoing discussion has given specific embodiments, those skilled in the art will recognize that changes can be made in form and detail without departing from the broader spirit and scope of the present invention. Therefore, the description and drawings should be regarded as illustrative rather than restrictive. Therefore, this detailed description should not be regarded as limiting, and the scope of the present invention is defined only by the claims included and the full scope of equivalents to which such claims are entitled.
