Description

[0001] Cross-reference to related applications

[0002] This application claims priority to Japanese Patent Application No. 2023-179973, filed on October 19, 2023, the entire disclosure of which is incorporated herein by reference. Technical Field

[0003] This disclosure generally relates to liquid crystal display devices. Background Technology

[0004] In the related art, liquid crystal display devices having multiple liquid crystal display panels stacked on top of each other are known. For example, unexamined Japanese Patent Application Publication No. 2023-000275 discloses a display device having color display elements (color liquid crystal elements) and a liquid crystal display panel having stacked color display elements.

[0005] In unexamined Japanese Patent Application Publication No. 2023-000275, a TFT substrate for a liquid crystal display panel has a plurality of first buses extending along a first direction and a plurality of second buses extending along a second direction intersecting the first direction. At least one of the plurality of first buses and at least one of the plurality of second buses 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 bending in a first direction, and a second bus extends while bending in a second direction, such that the first and second buses overlap with the sub-pixels of all colors of the color liquid crystal element. This suppresses the occurrence of moiré patterns.

[0007] In the liquid crystal display panel of unexamined Japanese Patent Application Publication No. 2023-000275, the switching elements (thin-film transistors) are 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, which includes multiple sub-pixels of the color display element. Therefore, the switching elements of the liquid crystal display panel are arranged with wide spacing in the first and second directions, blocking light incident from the backlight onto the color liquid crystal element (when the color liquid crystal element is arranged on the observer's side) or light emitted from the color liquid crystal element (when the liquid crystal display panel is arranged on the observer's side). When the switching elements block light with wide spacing, the switching elements protrude, and the dark areas caused by the switching elements may be perceived by the observer as display inconsistencies.

[0008] This disclosure is made in view of the above circumstances, and the object of this disclosure is to provide a liquid crystal display device that suppresses moiré patterns and also suppresses display inconsistencies caused by light-shielding elements. Summary of the Invention

[0009] To achieve the above objectives, the liquid crystal display device disclosed herein includes:

[0010] A first liquid crystal display panel displays color display elements, and a first main pixel comprising multiple sub-pixels of different colors is arranged therein; and

[0011] The second liquid crystal display panel overlaps with the first liquid crystal display panel and displays monochrome display elements, and includes second main pixels corresponding to a plurality of first main pixels, wherein:

[0012] The second liquid crystal display panel includes a switching element that drives a second main pixel and has light-blocking properties, a first light-blocking pattern that extends and repeats along a predetermined first direction and has light-blocking properties, a second light-blocking pattern that extends and repeats along a predetermined second direction perpendicular to the first direction and has light-blocking properties, and a plurality of light-shielding members that have light-blocking properties.

[0013] The first light-blocking pattern includes a first light-blocking line and a second light-blocking line. The first light-blocking line extends in a first direction and includes 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. The second light-blocking line is adjacent to the first light-blocking line and is linearly symmetrical to the first light-blocking line with respect to the first direction.

[0014] Multiple light-blocking elements are each located within a region between a cross line and the axis of symmetry of a first light-blocking pattern. This cross line connects the intersection of the first and second light-blocking patterns and extends in a first direction. The region is enclosed by the first and second light-blocking patterns, and the spacing between the first and second light-blocking lines continuously widens from both ends of the region in the first direction.

[0015] At least one of the first and second blocking light rays is formed by the scanning wiring of the second liquid crystal display panel.

[0016] It should be understood that the above general description and the following detailed description are exemplary and explanatory, and not intended to limit this disclosure.

[0017] According to this 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 the opposite direction to the first inclined portion. The second light-blocking line is adjacent to the first light-blocking line and is linearly symmetrical with respect to the first direction. Therefore, moiré patterns can be suppressed. Furthermore, light-blocking elements are each located within a region between a cross line and the axis of symmetry of the first light-blocking pattern. This cross line connects the intersection of the first and second light-blocking patterns and extends in the first direction. This region is surrounded by the first and second light-blocking patterns, and the spacing between the first and second light-blocking lines continuously widens from both ends of the region in the first direction. As a result, the spacing between dark areas caused by the switching element and the light-blocking elements is narrowed, and therefore, display inconsistencies caused by dark areas can be suppressed.

[0046] In the following description, 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 The liquid crystal display device 10 according to this 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, which will be 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 onto 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 (the right direction on the paper) is called the "+X direction", the up direction (the up direction on the paper) is called the "+Y direction", and the direction perpendicular to the +X direction and the +Y direction (the front direction on the paper) is called the "+Z direction".

[0050] Panel section

[0051] Panel portion 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 LCD display panel

[0053] In one example, the first liquid crystal display panel 100 is implemented as a known transmission horizontal electric field type liquid crystal display panel. The first liquid crystal display panel 100 is an active matrix driven by thin film transistor (TFT) elements.

[0054] like Figure 2 As shown, the first liquid crystal display panel 100 includes first main pixels 102 arranged in a matrix. The first main pixels 102 include a red pixel 104R that emits red light, a green pixel 104G that emits green light, and a blue pixel 104B that emits blue light, defined by a black matrix BM. Note that the red pixel 104R, the green pixel 104G, and the blue pixel 104B can 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 opposing 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 liquid crystal 130 is sandwiched between the first TFT substrate 110 and the first opposing substrate 120. The first polarizing plate 132 is disposed on the first TFT substrate 110. The second polarizing plate 134 is disposed on the first opposing 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, TFT elements for selecting sub-pixels 104, a common electrode, a pixel electrode, and an alignment film for aligning the first liquid crystal 130 are provided (all not shown in the figures).

[0057] Furthermore, a plurality of common wirings, a plurality of signal wirings, and a plurality of scan wirings (not shown in the figures) are formed on the main surface 110a of the first TFT substrate 110. The common wirings supply a common potential to a common electrode, which applies a voltage to the first liquid crystal 130. The signal wirings supply voltage to the pixel electrode via the TFT element, and the pixel electrode applies a voltage to the first liquid crystal 130. The signal wirings extend in the Y direction and curve along the outline of the sub-pixel 104. The scan wirings supply voltage for operating the TFT element. The scan wirings extend linearly in the Y direction. The sub-pixel 104 is surrounded by the signal wirings and scan wirings. The TFT element is disposed at the intersection of the scan wirings and the signal wirings. A first polarizing plate 132 is disposed 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 opposing substrate 120 is opposite to the first TFT substrate 110 and is adhered to the first TFT substrate 110 by a sealing material 138. In one example, the first opposing 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 disposed on the main surface 120a of the first opposing substrate 120 on the side of the first liquid crystal 130. In one example, the color filter 122 is implemented as a striped color filter, wherein color filters of the same color are arranged in the Y direction (where the striped direction is the color filter in the Y direction). The red, green, and blue color filters of the color filter 122 are all surrounded by the black matrix BM and correspond to the red pixel 104R, green pixel 104G, and blue pixel 104B, respectively. Figure 2 As shown, the black matrix BM defines each first main pixel 102 and each sub-pixel 104. A second polarizing plate 134 is disposed on the main surface 120b of the first opposing substrate 120, on the side opposite to the main surface 120a. Note that, for ease of understanding, Figure 3 The black matrix BM, alignment film, and similar components are omitted.

[0059] like Figure 3 As shown, the first liquid crystal 130 is sandwiched between the first TFT substrate 110 and the first opposing substrate 120. In one example, the first liquid crystal 130 is implemented as a non-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 an alignment film. Furthermore, 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] A first polarizing plate 132 is disposed on the main surface 110b of the first TFT substrate 110. A second polarizing plate 134 is disposed on the main surface 120b of the first opposing substrate 120. Either the transmission axis of the first polarizing plate 132 or the transmission axis of the second polarizing plate 134 is aligned parallel to the alignment direction of the first liquid crystal 130, and the transmission axes of the first polarizing plate 132 and the second polarizing plate 134 are orthogonal to each other. The first polarizing plate 132 is adhered to the second opposing substrate 220 of the second liquid crystal display panel 200 (described below) via a light-transmitting adhesive layer 150. In one example, the adhesive layer 150 is implemented as an optically clear adhesive (OCA).

[0061] A first driving circuit 136 is disposed on the main surface 110a of the first TFT substrate 110. The first driving circuit 136 supplies voltage to the scan wiring, signal wiring and common wiring based on the color signal supplied from the display controller 400.

[0062] Second LCD display panel

[0063] like Figure 3 As shown, the second liquid crystal display panel 200 is positioned on 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 by an adhesive layer 150. The second liquid crystal display panel 200 displays monochrome display elements.

[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 a non-parallel phase liquid crystal. The second liquid crystal display panel 200 is an active matrix driven by the 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 in Figure 4 In the figures below, scan routing GL and signal routing DL are shown as dashed lines. In the accompanying drawings, scan routing GL and signal routing DL may be shown as dashed or solid lines.

[0065] like Figure 3As shown, the second liquid crystal display panel 200 includes a second TFT substrate 210, a second opposing 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 opposing 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 also serves as the 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 lines GL; a plurality of signal lines DL; a common line (not shown); a switching element 240, a pixel electrode 250, and a common electrode CE for the second main pixel 202; an alignment film (not shown) for aligning the second liquid crystal 230; and the like (described in full later) are formed on the main surface 210a of the second TFT substrate 210. The common line supplies a common potential to the common electrode CE, which applies a voltage to the second liquid crystal 230. The signal lines DL supply a voltage to the pixel electrode 250 via the switching element 240, which applies a voltage to the second liquid crystal 230. The scan lines GL supply a voltage for operating the switching element 240. A third polarizer 232 is disposed on the main surface 210b of the second TFT substrate 210 on the side opposite to the main surface 210a.

[0067] In this embodiment, the scan wiring GL forms the first light-blocking pattern 260 described below. The signal wiring DL forms the second light-blocking pattern 270 described below. As described below, the switching element 240 has light-blocking properties. Furthermore, the end of the drain 248 of the switching element 240 that connects to the pixel electrode 250 forms a light-shielding member 280. The configuration of the scan wiring GL, the signal wiring DL, the second main pixel 202 (switching element 240, pixel electrode 250, etc.), and the like will be described later.

[0068] The second opposing substrate 220 is opposite to the second TFT substrate 210 and is adhered to the second TFT substrate 210 by a sealing material 238. In one example, the second opposing substrate 220 is implemented as a glass substrate. An alignment film (not shown) for aligning the second liquid crystal 230 is disposed on the main surface 220a of the second opposing substrate 230 on the side of the second liquid crystal 220. An adhesive layer 150 is disposed on the main surface 220b of the second opposing substrate 220 on the side opposite to the main surface 220a. The second opposing 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 opposing substrate 220. In one example, the second liquid crystal 230 is implemented as a non-nematic liquid crystal. The second liquid crystal 230 is initially aligned in the Y direction by an alignment film. Due to the applied voltage, the second liquid crystal 230 rotates in the plane parallel to the main surface 210a of the second TFT substrate 210.

[0070] A 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 parallel to the alignment direction of the second liquid crystal 230. Note that the transmission axis of the third polarizing plate 232 is orthogonal to the transmission axis of the first polarizing plate 132 of the first liquid crystal display panel 100 (the polarizing plate on the light-emitting side of the second liquid crystal display panel 200). The second liquid crystal display panel 200 operates in a normally black mode.

[0071] The second driving circuit 236 is disposed on the main surface 210a of the second TFT substrate 210. The second driving circuit 236 supplies voltage to the scan 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, signal wiring DL, first light-blocking pattern 260 and 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 light-blocking properties. The scanning wiring GL is formed of a metal (aluminum (Al), molybdenum (Mo), or a similar metal). Figure 4 and Figure 5 As shown, the scan wiring GL extends in the X direction and is arranged in the Y direction. Furthermore, a pair of adjacent scan wirings GL form a first light-blocking pattern 260 extending in the X direction and having light-blocking properties. The first light-blocking pattern 260 is repeated in the Y direction. Here, the term "light-blocking property" refers to blocking at least a portion of the incident light. In this embodiment, the X direction corresponds to a predetermined first direction.

[0074] like Figure 5 As shown, one of a pair of adjacent scan lines GL (hereinafter also referred to as "first blocking line 262") 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 a counterclockwise direction relative to the +X direction. The second inclined portion 262b is inclined at an acute angle in the opposite direction (clockwise) to the +X direction relative to the first inclined portion 262a. 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] Another scan line GL (hereinafter also referred to as "second block light 264") in a pair of adjacent scan lines GL is linearly symmetrical to one scan line GL (first block light 262) with respect to the X direction. The second block light 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 block light 262 and is inclined at an acute angle clockwise with respect to the +X direction. The fourth inclined portion 264b is opposite to the second inclined portion 262b of the first block light 262 and is inclined at an acute angle counterclockwise with respect to the +X direction in the opposite direction (counterclockwise) to the third inclined portion 264a. The second flat portion 264c extends parallel to the X direction, is opposite to the first flat portion 262c of the first block light 262, and connects the third inclined portion 264a and the fourth inclined portion 264b to each other.

[0076] In this embodiment, the first blocking light 262 includes a first inclined portion 262a and a second inclined portion 262b inclined in the opposite direction to the first inclined portion 262a. Furthermore, the first blocking light 262 and the second blocking light 264 are linearly symmetrical with respect to the X direction. Therefore, as... Figure 5 As shown, the spacing (spacing L1) between the first blocking light 262 and the second blocking light 264 continuously varies along the X-direction between the first inclined portion 262a of the first blocking light 262 and the third inclined portion 264a of the second blocking light 264. Furthermore, the spacing (spacing L2) between the first blocking light 262 and the second blocking light 264 also continuously varies along the X-direction between the second inclined portion 262b of the first blocking light 262 and the fourth inclined portion 264b of the second blocking light 264. Additionally, the spacing (spacing L3 and spacing L4) between the first flat portion 262c of the first blocking light 262 and the second flat portion 264c of the second blocking light 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, spatial frequency interference between the second liquid crystal display panel 200 and the first liquid crystal display panel 100 can be suppressed, thereby suppressing moiré patterns in the liquid crystal display device 10.

[0077] Next, the signal wiring DL and the second light-blocking pattern 270 are described. Like the scan wiring GL, the signal wiring DL has light-blocking properties. The signal wiring DL is formed of a metal (aluminum (Al), molybdenum (Mo), or a similar metal). Figure 4 and Figure 5As shown, the signal wiring DL extends along the Y direction and is arranged in the X direction. Furthermore, a pair of adjacent signal wiring DLs form a second light-blocking pattern 270 that extends in the Y direction and has light-blocking properties. In this embodiment, the Y direction corresponds to a predetermined second direction.

[0078] like Figure 5 As shown, one of a pair of adjacent signal traces DL (hereinafter also referred to as "third blocking light 272") includes a fifth tilt portion 272a and a sixth tilt portion 272b. The fifth tilt portion 272a is tilted at an acute angle in a counterclockwise direction relative to the +Y direction. The sixth tilt portion 272b is tilted at an acute angle in the opposite direction (clockwise direction) relative to the +Y direction to the fifth tilt portion 272a.

[0079] Another signal wiring DL (hereinafter also referred to as "fourth opaque line 274") in a pair of adjacent signal wiring DLs is linearly symmetrical with respect to a signal wiring DL (third opaque line 272) in the Y direction. The fourth opaque 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 opaque line 272 and is inclined at an acute angle in a clockwise direction relative to the +Y direction. The eighth inclined portion 274b is opposite to the sixth inclined portion 272b of the third opaque line 272 and is inclined at an acute angle in the opposite direction (counterclockwise direction) relative to the +Y direction to the seventh inclined portion 274a.

[0080] In this embodiment, the third blocking light 272 includes a fifth inclined portion 272a and a sixth inclined portion 272b inclined in the opposite direction to the fifth inclined portion 272. Furthermore, the third blocking light 272 and the fourth blocking light 274 are linearly symmetrical with respect to the Y direction. Therefore, as... Figure 5 As shown, the spacing L5 between the third blocking light 272 and the fourth blocking light 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, spatial frequency interference between the second liquid crystal display panel 200 and the first liquid crystal display panel 100 can be suppressed, thereby suppressing moiré patterns in the liquid crystal display device 10.

[0081] Next, refer to Figures 6 to 11 The scan wiring GL (first obscured light 262 and second obscured light 264), signal wiring DL (third obscured light 272 and fourth obscured light 274) and second main pixel 202 are described. Figure 6 The scan wiring GL and signal wiring DL corresponding to a second main pixel 202, the switching element 240 and contact holes CH1, CH2 of the second main pixel 202, and the light shield 280 are shown. Figure 6As shown, the second main pixel 202 is essentially rectangular in shape. The second main pixel 202 is divided into eight regions 202A in two rows and four columns along the X and Y directions. Note that in... Figure 6 In the figures below, for ease of understanding, the switching element 240, contact holes CH1 and CH2, and light-shielding member 280 are shown in solid lines and in a simplified manner. For convenience, the contact holes CH1 and 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 switching element 240, contact hole CH2, light-shielding member 280, and the like are sometimes shown in a simplified manner in the following figures.

[0082] Figure 7 Two regions 200A of the eight regions 202A of the second main pixel 202 are shown. (See diagram) Figure 7 As shown, two pixel electrodes 250 are arranged in each region 202A. The two pixel electrodes 250 arranged in a region 202A are connected to a switching element 240. A second main pixel 202 (16 pixel electrodes 250) is driven by voltages (signals) from a pair of adjacent scan lines GL and a pair of adjacent signal lines 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 scan lines GL can be implemented as two scan lines GL branching from one scan line. The pair of adjacent signal lines DL can be implemented as two signal lines DL branching from one signal line. Note that, for ease of understanding, Figure 7 The common electrode CE is omitted in the figure. The common electrode CE may also be omitted in some of the figures mentioned below.

[0083] A 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, as well as the scan wiring GL and signal wiring DL corresponding to the second main pixel 202, are linearly symmetrical with respect to the X and Y directions.

[0084] like Figure 9 As shown, scan wiring GL (first blocking light 262 and second blocking light 264) is formed on the main surface 210a of the second TFT substrate 210 and covered by the first insulating layer 292. Signal wiring DL (third blocking light 272 and fourth blocking light 274) is formed on the first insulating layer 292 and 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 a third insulating layer 296.

[0086] like Figure 7 As shown, each pixel electrode 250 of the second main pixel 202 has a comb-like shape. Two pixel electrodes 250 are arranged in a region 202A. The two pixel electrodes 250 arranged in region 202A are connected to a switching element 240 (drain 248). Figures 8 to 10 As shown, pixel electrode 250 is formed on third insulating layer 296. In one example, pixel electrode 250 is formed of ITO. Pixel electrode 250 and common electrode CE provide auxiliary capacitance for maintaining the signal voltage applied to second liquid crystal 230.

[0087] like Figure 6 and Figure 7 As shown, the switching element 240 of the second main pixel 202 is arranged along the scan wiring GL (first opaque line 262 and second opaque line 264). In this embodiment, the two switching elements 240 are arranged at the intersection P1 of the scan wiring GL and the signal wiring DL. In other words, the two switching elements 240 are arranged along the first inclined portion 262a and the second inclined portion 262b of the first opaque line 262 and the third inclined portion 264a and the fourth inclined portion 264b of the second opaque line 264, passing through the intersection P1 of the first opaque pattern 260 (first opaque line 262 and second opaque line 264) and the second opaque pattern 270 (third opaque line 272 and fourth opaque line 274).

[0088] The switching element 240 has light-blocking properties. In this embodiment, each switching element 240 also functions as a light-shielding element, blocking 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 Figure 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, source 246, and drain 248 are formed of a metal with light-blocking properties, such as aluminum (Al), molybdenum (Mo), or a similar metal. 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 from... Figure 11 The first insulating layer 292 is omitted.

[0090] The gate 242 is integrally formed with the scan wiring GL on the main surface 210a of the second TFT substrate 210. Like the scan wiring GL, the gate 242 is covered by the first insulating layer 292. Since the gate 242, which is formed on the same layer as the scan wiring GL (the first light blocking light 262 and the second light blocking light 264), is formed of a metal with light blocking properties, the switching element 240 has light blocking properties and also functions as a light shield.

[0091] The semiconductor layer 244 is disposed above the gate 242 in an island-like manner via the first insulating layer 292. The source 246 is integrally formed with the signal wiring DL.

[0092] The drain 248 branches into two drains 248. Each branch drain 248 is connected to the pixel electrode 250 at the contact portion 248a via a contact hole CH1 or contact hole CH2 penetrating the third insulating layer 296 and the second insulating layer 294. Figure 7 , Figure 9 and Figure 10 Since the contact portion 248a of the drain 248 is connected to the pixel electrode 250 formed of ITO with light-transmitting properties via the contact hole CH1 or contact hole CH2 penetrating the third insulating layer 296 and the second insulating layer 294, the contact portion 248a acts as a light-shielding member to block light.

[0093] When viewed from above, the contact portion 248a of the drain 248 of a pixel electrode 250, which is connected via contact hole CH1, is positioned above the scan wiring GL. Figure 6 , Figure 7 and Figure 9 The contact portion 248a of the drain 248 of another pixel electrode 250, connected via contact hole CH2, is located between the cross line CL and the axis of symmetry SL of the scan wiring GL within region S1. The cross line CL connects the intersection point P1 of the scan wiring GL and the signal wiring DL and extends in a first direction. Region S1 is the region surrounded by the scan wiring GL and the signal wiring DL, wherein the spacing L of the pair of scan wirings GL continuously widens from both ends of region S1 along the X direction. Figure 6 In other words, the contact portion 248a connected to another pixel electrode 250 via the contact hole CH2 is located between the cross line CL in region S1 and the axis of symmetry SL of the first light-blocking pattern 260. The cross 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. Region S1 is the area surrounded by the first light-blocking pattern 260 (first light-blocking line 262 and second light-blocking line 264) and the second light-blocking pattern 270 (third light-blocking line 272 and fourth light-blocking line 274), and the spacing L between the first light-blocking line 262 and the second light-blocking line 264 continuously widens from both ends of region S1 in the X direction.

[0094] In this embodiment, since the contact portion 248a of the drain 248 of one pixel electrode 250, which is connected to the contact hole CH1, is positioned above the scan wiring GL, i.e., above the first light blocking light 262 or the second light blocking light 264, the contact portion 248a essentially does not function as a light-shielding element. Conversely, the contact portion 248a of the drain 248 of another pixel electrode 250, which is connected to the contact hole CH2, functions as a light-shielding element and forms a light-shielding element 280. The light-shielding element 280 blocks 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, as Figure 6 As shown, a light-shielding member 280 corresponding to a switching element 240 is located in region S1 between the intersecting line CL and the axis of symmetry SL of the first light-blocking pattern 260. The intersecting 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. Region S1 is the area surrounded by the first light-blocking pattern 260 (first light-blocking line 262 and second light-blocking line 264) and the second light-blocking pattern 270 (third light-blocking line 272 and fourth light-blocking line 274), wherein the distance L between the first light-blocking line 262 and the second light-blocking line 264 continuously widens from both ends of region S1 along the X direction. Within region S1, two light-shielding members 280 are aligned in region S1 along the X direction between the intersecting line CL and the axis of symmetry SL, and four light-shielding members 280 are located within region S1. The four light-shielding members 280 are located in a position that is linearly symmetrical with respect to the X and Y directions.

[0096] like Figures 8 to 10 As shown, the first insulating layer 292 covers the scan wiring GL and the gate 242 of the switching element 240. The second insulating layer 294 covers the semiconductor layer 244, source 246, and drain 248 of the switching element 240, as well as 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 dioxide (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. Therefore, as Figure 6As shown, the switching element 240, which has light-blocking properties, is aligned with a wide spacing in the X and Y directions. Therefore, if light emitted from the backlight 300 and incident on the sub-pixels 104 of the first liquid crystal display panel 100 is blocked only by the switching element 240, the spacing between the dark areas caused by the switching element 240 will become wider, and the dark areas caused by the switching element 240 can be perceived by the observer as display inconsistency.

[0098] In this embodiment, the light-shielding member 280 is located in region S1 between the intersection line CL and the axis of symmetry SL, and blocks light emitted from the backlight 300 and incident on the sub-pixels 104 of the first liquid crystal display panel 100. As a result, dark areas are 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's perception of dark areas as display inconsistencies. In other words, display inconsistencies caused by dark areas can be suppressed.

[0099] Next, the arrangement of the first light-blocking pattern 260 (scan wiring GL), the second light-blocking pattern 270 (signal wiring DL), the switching element 240, and the light-blocking member 280 that overlap with the sub-pixels 104 of the first liquid crystal display panel 100 will be described.

[0100] like Figure 12 As shown, in the first light-blocking pattern 260, the first inclined portion 262a and the second inclined portion 262b of the first light-blocking line 262, and the third inclined portion 264a and the fourth inclined portion 264b of the second light-blocking line 264, obliquely pass through multiple sub-pixels 104 (104R, 104G, 104B) of different colors in the first liquid crystal display panel 100. Therefore, the brightness of the sub-pixels 104 overlapping with the first light-blocking pattern 260 is slightly reduced, and the first main pixel 102, including the sub-pixels 104 overlapping with the first light-blocking pattern 260, displays a color slightly different from the color intended to be displayed. However, since the sub-pixels 104 exhibiting similar degrees of brightness reduction are positioned very close together, the brightness of the sub-pixels 104 is average to an observer viewing the liquid crystal display device 10, and the observer perceives the brightness of the multiple sub-pixels 104 with reduced brightness as the same brightness level. Therefore, for the entire display of the liquid crystal display device 10, the observer's perception of color moiré patterns can be suppressed.

[0101] In the second light-blocking pattern 270, the fifth tilted portion 272a and the sixth tilted portion 272b of the third light-blocking line 272 and the seventh tilted portion 274a and the eighth tilted portion 274b of the fourth light-blocking line 274 tilt through a plurality of sub-pixels 104 (104R, 104B) of different colors of the first liquid crystal display panel 100. Therefore, similar to the first light-blocking pattern 260, the first main pixel 102, including the sub-pixels 104 overlapping with the second light-blocking pattern 270, presents a color slightly different from the intended color. However, the color presented by the first main pixel 102, including the sub-pixels 104 overlapping with the second light-blocking pattern 270, and the color presented by the number of first main pixels 102 located near the first main pixel 102, including the sub-pixels 104 overlapping with the second light-blocking pattern 270, are perceived by the observer as different colors, and the saturation of the mixed colors also decreases. Therefore, for the entire display of the liquid crystal display device 10, the observer's perception of color moiré patterns can be suppressed.

[0102] The switching element 240 and the light-shielding element 280 overlap with a portion of the sub-pixel 104. For example... Figure 12 As shown, preferably, the light-shielding member 280 is located on a straight line PL1 extending in the Y direction, connecting one end of the first flat portion 262c and one end of the second flat portion 264c, or on a straight line PL2 extending in the Y direction, connecting the other end of the first flat portion 262c and the other end of the second flat portion 264c. 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). Furthermore, preferably, 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). This configuration allows for the suppression of display inconsistencies caused by dark areas.

[0103] Backlight

[0104] like Figure 1 and Figure 3 As shown, the backlight 300 is arranged on the rear surface (-Z side) of the second liquid crystal display panel 200. In one example, the backlight 300 is implemented as a direct-lit backlight. The backlight 300 includes a white light-emitting diode (LED), a reflective sheet, a diffuser sheet, and the like (none shown in the figures).

[0105] The display controller 400 controls the display of the first liquid crystal display panel 100 and the second liquid crystal display panel 200. For example... Figure 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] Image data distributor 410 distributes input image data to first image signal generator 420 and second image brightness signal generator 430.

[0107] The first image signal generator 420 generates color display elements to be displayed on the first liquid crystal display panel 100 based on the input image data allocated by the image data distributor 410. Specifically, the first grayscale converter 422 of the first image signal generator 420 performs grayscale conversion to convert the distributed input image data into color data with brightness-grayscale characteristics suitable for the first liquid crystal display panel 100. In one example, a lookup table in which input / output relationships are preset is used in the data conversion. The first image signal generator 420 sends a color signal representing the generated color display elements to the first driving circuit 136 of the first liquid crystal display panel 100.

[0108] The second image luminance signal generator 430 generates a luminance signal based on the input image data allocated by the image data distributor 410, used to generate monochrome display elements to be displayed on the second liquid crystal display panel 200. In one example, the second image luminance signal generator 430 calculates the luminance level of a second main pixel 202 of the second liquid crystal display panel 200 based on the average, frequency, minimum, maximum, and similar values ​​of the red, green, and blue grayscale values ​​of the 16 first main pixels 102 of the first liquid crystal display panel 100, which are emitted from a second main pixel 202 of the second liquid crystal display panel 200. The calculated luminance level can be a grayscale value. The second image luminance signal generator 430 sends a luminance signal representing the calculated luminance level to the second image signal generator 440.

[0109] The second image signal generator 440 generates monochrome display elements to be displayed on the second liquid crystal display panel 200 based on the luminance signal sent from the second image luminance signal generator 430. In one example, the second image signal generator 440 generates monochrome display elements that have undergone averaging and grayscale conversion. Specifically, in one example, the calculator 442 of the second image signal generator 440 uses a weighted average based on the distance to the target second main pixel 202 to average the luminance level of the second main pixel 202 located within a predetermined distance from the target second main pixel 202. Therefore, the second image signal generator 440 can generate monochrome display elements with blurred edges. Furthermore, the second grayscale converter 444 of the second image signal generator 440 generates monochrome data with luminance-grayscale characteristics 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 elements to the second driving circuit 236 of the second liquid crystal display panel 200.

[0110] Through brightness level calculation, averaging, and similar processing 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 synchronization circuit (not shown) for synchronizing the output of the monochrome and color signals. Due to this synchronization circuit, monochrome display elements corresponding to the color display elements of the first liquid crystal display panel 100 are displayed on the second liquid crystal display panel 200, and thus, appropriate color display elements are displayed on the liquid crystal display device 10.

[0111] The display controller 400 is configured with a graphics processing unit (GPU), memory, timing controller, power supply circuitry, and similar components. 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 realize the function of the display controller 400.

[0112] As described above, the first light-blocking pattern 260 (scan 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. The second light-blocking line 264 is linearly symmetrical with respect to the first light-blocking line in 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 thus, moiré patterns in the liquid crystal display device 10 can be suppressed. Furthermore, the occurrence of color moiré patterns can also be suppressed.

[0113] Furthermore, 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 tilted portion 272a and a sixth tilted portion 272b, and a fourth light-blocking line 274 that is linearly symmetrical with respect to the third light-blocking line 272 in 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 thus, moiré patterns in the liquid crystal display device 10 can be suppressed. Furthermore, the occurrence of color moiré patterns can also be suppressed.

[0114] Furthermore, the light-shielding member 280 is located within region S1 between the cross line CL and the axis of symmetry SL of the first light-blocking pattern 260. The cross 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. Region S1 is the area surrounded by the first light-blocking pattern 260 and the second light-blocking pattern 270, wherein the distance L between the first light-blocking line 262 and the second light-blocking line 264 continuously widens from both ends of region S1 in the X direction. As a result, the distance between the dark areas caused by the switching element 240 and the light-shielding member 280 is narrowed, and therefore, display inconsistencies caused by the light-shielding member (switching element 240 and light-shielding member 280) can be suppressed. As a result, the liquid crystal display device 10 can suppress moiré patterns and also suppress display inconsistencies caused by the light-shielding member.

[0115] In this embodiment, a switching element 240 is connected to two pixel electrodes 250. Therefore, even if defects occur in the pixel electrodes 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, it is also possible for the light-shielding member 280 to be formed by a virtual light-blocking layer.

[0118] Similar to 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 configuration of the first liquid crystal display panel 100, the first light-blocking pattern 260 and the second light-blocking pattern 270 (scan wiring GL and signal wiring DL) of the second liquid crystal display panel 200, the backlight 300, the display controller 400, and similar components in this embodiment is the same as that in Embodiment 1. Here, the second main pixel 202 and the light-blocking member 280 of the second liquid crystal display panel 200 are described.

[0119] Similarly, in this embodiment, the second liquid crystal display panel 200 includes second main pixels 202 arranged in a matrix. Figure 4 Furthermore, 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 Figure 14 As shown, the second main pixel 202 in this embodiment has a rectangular shape and is divided into eight regions 202A in two rows and four columns in the X and Y directions. Figure 15 As shown, a pixel electrode 250 is arranged in each region 202A. A pixel electrode 250 arranged in a region 202A is connected to a switching element 240. As in Embodiment 1, a second main pixel 202 (eight pixel electrodes 250) is driven by voltages (signals) from a pair of adjacent scan wirings GL and a pair of adjacent signal wirings DL.

[0121] like Figure 15 As shown, each pixel electrode 250 of the second main pixel 202 in this embodiment has a comb-like shape. In this embodiment, one pixel electrode 250 is arranged in a region 202A. One pixel electrode 250 is connected to a switching element 240 (the contact portion 248a of the drain 248) via a contact hole CH1 located above the scan wiring GL (the first light blocking light 262 and the second light blocking light 264). In this embodiment, since the contact portion 248a of the drain 248 of the pixel electrode 250 connected via the contact hole CH1 is positioned above the scan wiring GL, the contact portion 248a does not substantially function as a light-shielding element as in Embodiment 1.

[0122] Similar to Embodiment 1, in this embodiment, the switching elements 240 of the second main pixel 202 are arranged along the scan wiring GL. Figure 14 and Figure 15 Similarly, in this embodiment, two switching elements 240 are arranged through the intersection P1 of the scan wiring GL and the signal wiring DL (the third blocking light 272 and the fourth blocking light 274).

[0123] Similarly, in this embodiment, the switching element 240 has light-blocking properties. Except that the drain 248 is not branched and one drain 248 is connected to a switching element 240 via a contact hole CH1 located above the scan wiring GL, the configuration of the switching element 240 in this embodiment is the same as that in Embodiment 1.

[0124] Similar to the light-shielding member 280 in Embodiment 1, the light-shielding member 280 in this embodiment is located in region S1 between the intersection line CL and the axis of symmetry 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. Region S1 is the area surrounded by the first light-blocking pattern 260 (first light-blocking line 262 and second light-blocking line 264) and the second light-blocking pattern 270 (third light-blocking line 272 and fourth light-blocking line 274), and the distance L between the first light-blocking line 262 and the second light-blocking line 264 continuously widens from both ends of region S1 along the X direction. Figure 14 Furthermore, in region S1, two light-shielding elements 280 are aligned along the X direction between the intersection line CL and the axis of symmetry SL, and four light-shielding elements 280 are located within region S1. The four light-shielding elements 280 are positioned in a position that is linearly symmetrical with respect to the X and Y directions.

[0125] In this embodiment, the light-shielding element 280 is formed of a virtual light-blocking layer DM made of a metal, organic material, or similar material with light-blocking properties. In one example, such as... Figure 16 As shown, the light-shielding member 280 (virtual light-blocking layer DM) is formed on the main surface 210a of the second TFT substrate 210.

[0126] The configuration of the first light-blocking pattern 260 and the second light-blocking pattern 270 (scan wiring GL and 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 patterns and can also suppress display inconsistencies caused by the light-shielding members (switching element 240 and 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 elements 240 can 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-blocking members 280 can be formed from the contact portion 248a of the drain 248, and another portion of the plurality of light-blocking members 280 can be formed from the virtual light-blocking layer DM.

[0129] Similar to 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 configuration of the first liquid crystal display panel 100, the first light-blocking pattern 260 and the second light-blocking pattern 270 (scan wiring GL and signal wiring DL) of the second liquid crystal display panel 200, the backlight 300, the display controller 400, and similar components in this embodiment is the same as that in Embodiment 1. Here, the second main pixel 202 and the light-blocking member 280 of the second liquid crystal display panel 200 are described.

[0130] Similarly, in this embodiment, the second liquid crystal display panel 200 includes second main pixels 202 arranged in a matrix. Furthermore, 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 Figure 17 As shown, the second main pixel 202 in this embodiment has a rectangular shape and is divided into four regions 202A in two rows and two columns in the X and Y directions. Figure 18 As shown, a pixel electrode 250 is arranged in each region 202A. A pixel electrode 250 arranged in a region 202A is connected to a switching element 240. As in Embodiment 1, a second main pixel 202 (four pixel electrodes 250) is driven by voltages (signals) from a pair of adjacent scan wirings GL and a pair of adjacent signal wirings DL.

[0132] like Figure 18 As shown, each pixel electrode 250 of the second main pixel 202 in this embodiment has a comb-like shape. In this embodiment, one pixel electrode 250 is arranged in a region 202A. One pixel electrode 250 is connected to a switching element 240 (drain 248) via a contact hole CH. In this embodiment, similar to the contact portion 248a of the pixel electrode 250 connected via the contact hole CH2 in Embodiment 1, the contact portion 248a of the drain 248 of the pixel electrode 250 connected via the contact hole CH forms a light-shielding member 280.

[0133] like Figure 17 As shown, in this embodiment, the switching element 240 of the second main pixel 202 is arranged at the intersection P1 of the scan wiring GL and the signal wiring DL. In this embodiment, the switching element 240 also has light-blocking properties.

[0134] Similarly, in this embodiment, such as Figure 19As shown, the gate 242 of the switching element 240 is integrally formed with the scan wiring GL. Furthermore, the semiconductor layer 244 of the switching element 240 is disposed above the gate 242 in an island-like manner via the first insulating layer 292. The source 246 of the switching element 240 is integrally formed with the signal wiring DL. The drain 248 of the switching element 240 is connected to the pixel electrode 250 at the contact portion 248a via the contact hole CH. Figure 18 The configuration of the first insulating layer 292, the second insulating layer 294, and the like is the same as in Embodiment 1. Furthermore, Figure 19 The first insulating layer 292 is omitted.

[0135] Similar to the light-shielding member 280 in Embodiment 1, the light-shielding member 280 in this embodiment is located in region S1 between the intersecting line CL and the axis of symmetry SL of the first light-blocking pattern 260. The intersecting 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. Region S1 is the area surrounded by the first light-blocking pattern (first light-blocking line 262 and second light-blocking line 264) and the second light-blocking pattern 270 (third light-blocking line 272 and fourth light-blocking line 274), and the distance L between the first light-blocking line 262 and the second light-blocking line 264 continuously widens from both ends of region S1 along the X direction. Figure 17 Furthermore, in region S1, two light-shielding elements 280 are aligned along the X direction between the intersection line CL and the axis of symmetry SL, and four light-shielding elements 280 are located within region S1. The four light-shielding elements 280 are located in a position that is linearly symmetrical with respect to the X and Y directions. In this embodiment, one of the two light-shielding elements 280 arranged in the X direction is formed by a contact portion 248a of a drain 248, which is connected to a pixel electrode 250 via a contact hole CH. Similar to the light-shielding element 280 in Embodiment 2, the other light-shielding element 280 of the two light-shielding elements 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 (scan wiring GL and signal wiring DL) in this embodiment is the same as that in Embodiment 1. Therefore, the liquid crystal display device 10 of this embodiment can also suppress color moiré patterns. In this embodiment, the switching element 240 is arranged at the intersection point P1 of the scan wiring GL and the signal wiring DL, and the light-blocking member 280 is located in region S1 between the intersection line CL and the axis of symmetry SL. Therefore, the spacing between the dark areas formed by the light-blocking members (switching element 240 and light-blocking member 280) is narrowed. Therefore, the liquid crystal display device 10 of this embodiment can also suppress display inconsistencies caused by dark areas. As described above, like the liquid crystal display device 10 of Embodiment 1, the liquid crystal display device 10 of this embodiment can suppress moiré patterns and can also suppress display inconsistencies caused by the light-blocking members (switching element 240 and light-blocking 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 elements 280 is formed by the contact portion 248a of the drain 248. The switching element 240 can be arranged at the intersection P1 of the scan wiring GL and the signal wiring DL, and all of the plurality of light-shielding elements 280 can be formed by a virtual 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 in this embodiment are the same as those in Embodiment 3.

[0140] like Figure 20 and 21 As shown, in this embodiment, the contact hole CH is disposed near the switching element 240. Furthermore, when the first liquid crystal display panel 100 and the second liquid crystal display panel 200 overlap, the contact hole in this 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 248) in this embodiment is connected to the pixel electrode 250 via the contact hole CH. In this 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 248 essentially does not function as a light-shielding element to block light incident on the sub-pixel 104 (first main pixel 102) of the first liquid crystal display panel 100.

[0141] In this embodiment, all light-blocking elements 280 are formed of a virtual light-blocking layer DM. The configuration of the virtual light-blocking layer DM in this embodiment is the same as that in Embodiment 2.

[0142] Similar to embodiments 1 to 3, in this embodiment, the light-shielding member 280 is located in region S1 between the intersecting line CL and the axis of symmetry SL of the first light-blocking pattern 260. The intersecting 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. Region S1 is the area surrounded by the first light-blocking pattern 260 (first light-blocking line 262 and second light-blocking line 264) and the second light-blocking pattern 270 (third light-blocking line 272 and fourth light-blocking line 274), and the distance L between the first light-blocking line 262 and the second light-blocking line 264 continuously widens from both ends of region S1 along the X direction. Figure 20 Furthermore, in region S1, two light-shielding elements 280 are aligned along the X direction between the intersection line CL and the axis of symmetry SL, and four light-shielding elements 280 are located within region S1. The four light-shielding elements 280 are positioned in a position that is linearly symmetrical with respect to the X and Y directions.

[0143] The configuration of the first light-blocking pattern 260 and the second light-blocking pattern 270 (scan wiring GL and 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 patterns and can also suppress display inconsistencies caused by the light-shielding members (switching element 240 and light-shielding member 280).

[0144] Example 5

[0145] 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 elements 280 is formed by contact holes CH. The switching element 240 can be arranged at the intersection P1 of the scan wiring GL and the signal wiring DL, and all of the plurality of light-shielding elements 280 can be formed by contact portions 248a of the drain 248.

[0146] Similar to 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 configuration of the first liquid crystal display panel 100, the first light-blocking pattern 260 and the second light-blocking pattern 270 (scan wiring GL and signal wiring DL) of the second liquid crystal display panel 200, the backlight 300, the display controller 400, and similar components in this embodiment is the same as the configuration of these components in Embodiments 1 to 4. Here, the second main pixel 202 and the light-blocking member 280 of the second liquid crystal display panel 200 are described.

[0147] Similarly, in this embodiment, the second liquid crystal display panel 200 includes second main pixels 202 arranged in a matrix. Furthermore, 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 Figure 22 As shown, the second main pixel 202 in this embodiment has a rectangular shape and is divided into four regions 202A in two rows and two columns in the X and Y directions. In this embodiment, as... Figure 23 As shown, two pixel electrodes 250 are arranged in each region 202A. The two pixel electrodes 250 arranged in a region 202A are connected to a switching element 240. As in Embodiment 1, a second main pixel 202 (eight pixel electrodes 250) is driven by voltages (signals) from a pair of adjacent scan lines GL and a pair of adjacent signal lines DL.

[0149] like Figure 23 As shown, each pixel electrode 250 of the second main pixel 202 in this embodiment has a comb-like shape. In this embodiment, two pixel electrodes 250 are arranged in a region 202A. In this embodiment, the two pixel electrodes 250 are connected to a switching element 240. The pixel electrodes 250 are connected to the switching element 240 (the contact portion 248a of the drain 248) via a contact hole CH. In this embodiment, as in Embodiment 3, the contact portion 248a of the drain 248 of the pixel electrode 250 connected via the contact hole CH forms a light-shielding member 280.

[0150] Similar to the switching element 240 in Embodiment 4, the switching element 240 of the second main pixel 202 in this embodiment is arranged at the intersection P1 of the scan wiring GL and the signal wiring DL. Figure 22 The switching element 240 in this embodiment also has light-blocking properties.

[0151] Similarly, in this embodiment, such as Figure 24 As shown, the gate 242 of the switching element 240 is integrally formed with the scan wiring GL. Furthermore, the semiconductor layer 244 of the switching element 240 is disposed above the gate 242 in an island-like manner via the first insulating layer 292. The source 246 of the switching element 240 is integrally formed with the signal wiring DL. The drain 248 of the switching element 240 is connected to the pixel electrode 250 at the contact portion 248a via the contact hole CH. In this embodiment, a source 246 is disposed between two drains 248, and each drain 248 is connected to the corresponding pixel electrode 250 at the corresponding contact portion 248a. Figure 23 The structure of the first insulating layer 292, the second insulating layer 294, and similar components is the same as in Embodiment 1. Furthermore, Figure 24The first insulating layer 292 is omitted.

[0152] In this 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 light-shielding elements 280 in this embodiment are formed by a contact portion 248a connected to the drain 248 of the pixel electrode 250 via a contact hole CH. The light-shielding element 280 of this embodiment is similar to that of embodiments 1 to 4. Figure 22 The light-shielding elements 280 in the ) are arranged in the same way.

[0154] The configuration of the first light-blocking pattern 260 and the second light-blocking pattern 270 (scan wiring GL and signal wiring DL) in this embodiment is the same as that in embodiments 1 to 4. The arrangement of the switching element 240 and the light-blocking member 280 in this embodiment is the same as that in embodiment 4. Therefore, the liquid crystal display device 10 of this embodiment can also suppress moiré patterns and suppress display inconsistencies caused by the light-blocking members (switching element 240 and light-blocking member 280).

[0155] Furthermore, a switching element 240 is connected to both pixel electrodes 250. Therefore, even if defects occur in the pixel electrodes 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. Additionally, the source electrode 246 is disposed between the two drain electrodes 248, and thus the size of the switching element 240 can be reduced.

[0156] Modify Example

[0157] Although embodiments have been described above, various modifications may be made to this disclosure without departing from its scope.

[0158] For example, in one embodiment, the first liquid crystal display panel 100 and the second liquid crystal display panel 200 are operated using a horizontal electric field method. However, the operation method of the first liquid crystal display panel 100 and the second liquid crystal display panel 200 can be determined as needed.

[0159] In this 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 observer-side surface of the first liquid crystal display panel 100. The second liquid crystal display panel 200 can be positioned on the observer side, and the first liquid crystal display panel 100 can be positioned on the side opposite to the observer-side surface of the second liquid crystal display panel 200.

[0160] In this embodiment, the first polarizing plate 132 of the first liquid crystal display panel 100 also serves as the polarizing plate on the light-emitting side of the second liquid crystal display panel 200. However, it is possible for the second liquid crystal display panel 200 to include a polarizing plate on the main surface 220b of the second opposing substrate 220.

[0161] In this embodiment, the stripe direction of the color filter 122 of the first liquid crystal display panel 100 is the Y direction. It is also possible for the color filter 122 of the first liquid crystal display panel 100 to have a stripe direction in the X direction.

[0162] In this 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 one embodiment, the first liquid crystal display panel 100 includes a first liquid crystal 130 implemented as a forward-phase liquid crystal. The second liquid crystal display panel 200 includes a second liquid crystal 230 implemented as a forward-phase liquid crystal. The first liquid crystal 130 may be implemented as a negative-phase liquid crystal. The second liquid crystal 230 may be implemented as a negative-phase liquid crystal.

[0164] In this 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, it is possible for the first light-blocking line 262 to not include the first flat portion 262c, and the second light-blocking line 264 to not include the second flat portion 264c. That is, the first light-blocking line 262 and the second light-blocking line 264 can have a linear symmetry relationship with respect to the X direction, and each extends in a zigzag pattern in the X direction.

[0165] Meanwhile, it is possible for the third light-blocking line 272 of the second light-blocking pattern 270 to include a third flat portion that connects the fifth inclined portion 272a and the sixth inclined portion 272b to each other and extends parallel to the Y direction. Additionally, it is possible for the fourth light-blocking line 274 of the second light-blocking pattern 270 to include a fourth flat portion that connects the seventh inclined portion 274a and the eighth inclined portion 274b to each other and extends parallel to the Y direction.

[0166] Furthermore, the second light-blocking pattern 270 (the third light-blocking line 272 and the fourth light-blocking line 274) can be in a straight line.

[0167] In an embodiment, the scanning wiring GL forms a first light-blocking line 262 and a 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: when 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. It is also possible for the second light-blocking line 264 to be a light-shielding element (light-blocking pattern) formed of an organic material with light-blocking properties.

[0168] The second light-blocking pattern 270 does not need to be formed by signal wiring DL. For example, it is possible for the second light-blocking pattern 270 to be configured as a light-shielding member formed of an organic material with light-blocking properties. Furthermore, it is possible for one of the third light-blocking line 272 and the fourth light-blocking line 274 of the second light-blocking pattern 270 to be formed by signal wiring DL, and the other to be formed by an organic material with light-blocking properties.

[0169] In this embodiment, the source 246 of the switching element 240 is linear, but the source 246 can also be U-shaped. For example, as... Figure 25 As shown, each switching element 240 in Embodiment 3 may include a U-shaped source 246. Therefore, the size of the switching element 240 can be reduced. Figure 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 corresponding to one second main pixel 202 of the second liquid crystal display panel 200 can be set as needed.

[0171] In this embodiment, the same gate signal (gate signal at the same timing) from a pair of adjacent scan lines GL and the same data signal from a pair of adjacent signal lines DL are input to the switching element 240, and thus drive a second main pixel 202 of the second liquid crystal display panel 200. The pair of adjacent scan lines GL can supply gate signals to the switching element 240 at different timings, and can also supply different data signals to the switching element 240. In this case, Embodiment 1 ( Figure 6 The configuration of a second primary pixel 202 corresponds to the modified example () Figure 26 The configuration of four (2×2) second primary pixels 202 in ).

[0172] Contact holes CH, CH1, and CH2 can be formed on multiple comb-like portions of the pixel electrode 250.

[0173] The contact portion 248a of the drain 248 forming the light-shielding element 280 is positioned at the bottom of the contact holes CH, CH1, and CH2. Therefore, it can be said that the contact hole CH2 in Embodiment 1 and the contact hole CH in Embodiments 3 and 5 function as a light-shielding element.

[0174] In Embodiment 1, a contact hole CH1 and a contact portion 248a connected to the drain 248 of the pixel electrode 250 via the contact hole CH1 are formed above the scan wiring GL. Figure 9 Meanwhile, no scan wiring GL is formed below the contact hole CH2 and the contact portion 248a of the drain 248 connected to the pixel electrode 250 via the contact hole CH2. Figure 10 A light-shielding element can be formed below the contact hole CH2 and the contact portion 248a of the drain 248 connected to the pixel electrode 250 via the contact hole CH2, using the same material as the scan wiring GL. By forming this light-shielding element, the cross-sectional structures of the contact hole CH1 and the contact hole CH2 will be identical. Therefore, shape variations of the contact holes CH1 and CH2, as well as poor connections between the pixel electrode 250 and the drain 248, can be suppressed.

[0175] The wiring width of the drain 248, which connects to the contact portion 248a (light-shielding member 280) of the pixel electrode 250 via contact holes CH and CH2, between the drain 248 and the switching element 240, is preferably narrower than the wiring width of the signal wiring DL and the scanning wiring GL. Therefore, the light-blocking effect achievable by the drain 248 between the contact portion 248a and the switching element 240 is less than the light-blocking effect achievable by the contact portion 248a (light-shielding member 280). However, by adjusting the wiring width of the drain 248 between the contact portion 248a and the switching element 240, the entire drain 248 can function as a light-shielding member.

[0176] In this embodiment, a virtual light-blocking layer DM (light-shielding member 280) is formed above the main surface 210a of the second TFT substrate 210. However, the location 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. Furthermore, a configuration in which the virtual light-blocking layer DM is disposed on the second opposing substrate 220 is also possible.

[0177] Preferably, a portion of the boundary BL between two adjacent pixel electrodes 250 runs along the scan wiring GL (first light-blocking pattern 260) or the signal wiring DL (second light-blocking pattern 270). For example, as Figure 27 As shown, the boundary BL of the pixel electrode 250 in Embodiment 1 may overlap with the scan wiring GL or the signal wiring DL. Note that, for ease of understanding, Figure 27The drain 248, contact holes CH1 and CH2, and similar components are omitted.

[0178] The switching element 240 of the second main pixel 202 can be arranged along the scan wiring GL (first blocking light 262 and second blocking light 264). In an embodiment, the switching element 240 is tilted relative to the X direction, but the switching element 240 can be formed along the X direction.

[0179] The foregoing has described some exemplary embodiments for illustrative purposes. Although specific embodiments have been given in the preceding discussion, those skilled in the art will recognize that changes in form and detail may be made without departing from the broader spirit and scope of the invention. Therefore, the specification and drawings should be regarded as illustrative rather than restrictive. Consequently, this detailed description should not be regarded as limiting, and the scope of the invention is defined only by the included claims and the full scope of their equivalents.
