Description

[Technical Field]

[0001] The present disclosure relates to a liquid crystal display panel and a liquid crystal display device. [Background Art]

[0002] Liquid crystal display devices with improved contrast obtained by stacking a plurality of liquid crystal display panels are known. For example, Patent Document 1 discloses a liquid crystal display device in which a plurality of display panels are arranged in an overlapping manner and each display panel displays an image, the liquid crystal display device including a first display panel that displays a color image and a second display panel that displays a black-and-white image.

[0003] In Patent Document 1, a pixel electrode of the second display panel has an outer shape of a substantially parallelogram, and a plurality of slits extending in the column direction are formed in the pixel electrode of the second display panel. Further, the pixel electrode of the second display panel includes a first side extending in the column direction, a second side extending in the column direction and opposite to the first side, a third side connecting one end of each of the first side and the second side, and a fourth side connecting the other end of each of the first side and the second side, wherein the third side and the fourth side are each inclined at a predetermined angle with respect to the row direction. In Patent Document 1, by inclining the third side and the fourth side with respect to the row direction, when an observer views the liquid crystal display device from an oblique direction, it is suppressed that the black matrix, wirings, and the like of the second display panel are visible to the observer through the openings of the pixels of the first display panel, and thus the black matrix, wirings, and the like are visually recognized by the observer as periodic brightness contrast. That is, by inclining the third side and the fourth side with respect to the row direction, generation of dark lines at boundaries between pixels adjacent in the column direction is suppressed. [Prior Art Documents] [Patent Documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2018-120045 [Patent Document 2] Japanese National Publication of International Patent Application No. 2020-513111 [Summary of the Invention] [Problems that the invention aims to solve]

[0005] When multiple liquid crystal display panels are stacked, the transmittance of the stacked display panel is the product of the transmittances of each individual display panel, and therefore it is lower than the transmittance of a single display panel. Consequently, it is desirable to improve the transmittance of each individual liquid crystal display panel being stacked. The second display panel in Patent Document 1 operates in transverse electric field mode, but some liquid crystal display panels that operate in transverse electric field mode have pixel electrodes formed from linear electrodes (branches) (for example, Patent Document 2). When pixel electrodes are formed from linear electrodes, even if the generation of dark lines is suppressed, disclination lines may be generated between adjacent pixels, and these disclination lines become dark areas, which may reduce the transmittance of the liquid crystal display panel.

[0006] This disclosure is made in view of the above circumstances and aims to provide a liquid crystal display panel and liquid crystal display device with high transmittance. [Means for solving the problem]

[0007] To achieve the above objectives, the liquid crystal display panel relating to the first aspect of this disclosure is: The device comprises a plurality of pixels, each having a pixel electrode, a common electrode, and a liquid crystal that rotates in the plane due to the voltage applied by the pixel electrode and the common electrode. The pixel electrode has a linear electrode, When the initial orientation direction of the liquid crystal with positive dielectric anisotropy, or the direction perpendicular to the initial orientation direction of the liquid crystal with negative dielectric anisotropy, is defined as a predetermined first direction, The linear electrode extends in the predetermined first direction, In the predetermined first direction adjacent pixels The linear electrode of one pixel and the linear electrode of the other pixel form, At the boundary, the boundary line between adjacent pixels, the linear electrode, and the end edge of the linear electrode are inclined with respect to the predetermined first direction, and the inclination direction of the boundary line, the linear electrode, and the end edge with respect to the predetermined first direction is the same.

[0008] The liquid crystal display device relating to the second aspect of this disclosure is The above-mentioned LCD display panel that displays monochrome images, It includes a color liquid crystal display panel that displays color images. [Effects of the Invention]

[0009] According to this disclosure, since the inclination direction of the boundary line between adjacent pixels and the linear electrodes and their ends with respect to a predetermined first direction are the same, the rotation of the liquid crystal at the boundary between adjacent pixels can be controlled, and the transmittance of the liquid crystal display panel can be improved.

DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, liquid crystal display panels and liquid crystal display devices according to embodiments will be described with reference to the drawings.

[0012] <Embodiment 1> With reference to FIGS. 1 to 15, a liquid crystal display device 10 and a liquid crystal display panel 200 according to the present embodiment will be described. The liquid crystal display device 10 displays a color image by means of a color liquid crystal display panel 100 and a liquid crystal display panel 200 which will be described later.

[0013] As shown in Figure 1, the liquid crystal display device 10 comprises a panel section 50, a backlight 300, and a display control unit 400. The panel section 50 has a color liquid crystal display panel 100 and a liquid crystal display panel 200. The backlight 300 is a light source that illuminates the color liquid crystal display panel 100 and the liquid crystal display panel 200. The display control unit 400 controls the display of the color liquid crystal display panel 100 and the liquid crystal display panel 200. For the sake of clarity, in this specification, the rightward direction (rightward direction on the page) of the liquid crystal display device 10 in Figure 1 is described as the +X direction, the upward direction (upward direction on the page) is described as the +Y direction, and the direction perpendicular to the +X and +Y directions (towards the front of the page) is described as the +Z direction.

[0014] (Panel section) The panel section 50 includes a color liquid crystal display panel 100 and a liquid crystal display panel 200. The color liquid crystal display panel 100 is located on the observer side (+Z side) and displays a color image. The liquid crystal display panel 200 is located on the opposite side of the color liquid crystal display panel 100 from the observer side (the back side of the color liquid crystal display panel 100) and overlaps the color liquid crystal display panel 100. The liquid crystal display panel 200 displays a monochrome image.

[0015] (Color LCD display panel) The color liquid crystal display panel 100 is, for example, a known transmissive transverse field type liquid crystal display panel. The color liquid crystal display panel 100 is actively matrix driven by a TFT (Thin Film Transistor).

[0016] As shown in Figure 2, the color liquid crystal display panel 100 has a rectangular display area 101 with main pixels 102 arranged in a matrix. The main pixels 102 are formed from red pixels 104R that emit red light, green pixels 104G that emit green light, and blue pixels 104B that emit blue light, which are defined in a V shape by a black matrix BM. Note that the red pixels 104R, green pixels 104G, and blue pixels 104B are sometimes collectively referred to as sub-pixels 104.

[0017] As shown in Figure 3, the color liquid crystal display panel 100 comprises 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 driver circuit 136. The first TFT substrate 110 and the first opposing substrate 120 sandwich the first liquid crystal 130. The first polarizing plate 132 is provided on the first TFT substrate 110, and the second polarizing plate 134 is provided on the first opposing substrate 120.

[0018] The first TFT substrate 110 is, for example, a glass substrate. The main surface 110a of the first TFT substrate 110 on the side facing the first liquid crystal 130 is provided with a TFT for selecting subpixels 104, a common electrode, a pixel electrode, an alignment film for aligning the first liquid crystal 130, etc. (none of which are shown).

[0019] Furthermore, a plurality of common wirings, a plurality of signal wirings, and a plurality of scanning wirings are formed on the main surface 110a of the first TFT substrate 110 (none of which are shown). The common wirings supply a common potential to a common electrode that applies voltage to the first liquid crystal 130. The signal wirings supply voltage to the pixel electrodes that apply voltage to the first liquid crystal 130 via the TFT. The scanning wirings supply voltage to operate the TFT. The sub-pixel 104 is surrounded by the signal wirings and the scanning wirings, and the TFT is provided at the intersection of the scanning wirings and the signal wirings. A first polarizing plate 132 is provided on the main surface 110b of the first TFT substrate 110, opposite to the main surface 110a.

[0020] As shown in Figure 3, the first opposing substrate 120 faces the first TFT substrate 110 and is bonded to the first TFT substrate 110 by a sealing material 138. The first opposing substrate 120 is, for example, a glass substrate. The main surface 110a of the first opposing substrate 120 on the side facing the first liquid crystal 130 is provided with a color filter layer 122, a black matrix BM, an alignment film for aligning the first liquid crystal 130, etc. The color filter layer 122 is, for example, a striped color filter. The red color filter, green color filter, and blue color filter of the color filter layer 122 are each surrounded by a black matrix BM and correspond to the red pixel 104R, green pixel 104G, and blue pixel 104B, respectively. A second polarizing plate 134 is provided on the main surface 120b of the first opposing substrate 120, opposite to the main surface 120a. Note that in Figure 3, the black matrix BM, alignment film, etc. are omitted for ease of understanding.

[0021] The first liquid crystal 130 is sandwiched between the first TFT substrate 110 and the first opposing substrate 120. The first liquid crystal 130 is, for example, a positive-type nematic liquid crystal. The first liquid crystal 130 is oriented in a direction parallel to the main surface 110a of the first TFT substrate 110 by an alignment film. Furthermore, when a voltage is applied, the first liquid crystal 130 rotates within a plane parallel to the main surface 110a of the first TFT substrate 110.

[0022] The first polarizing plate 132 is provided on the main surface 110b of the first TFT substrate 110, and the second polarizing plate 134 is provided on the main surface 120b of the first opposing substrate 120. The transmission axes of the first polarizing plate 132 and the second polarizing plate 134 are arranged such that the transmission axis of either polarizing plate is parallel to the orientation direction of the first liquid crystal 130. The first polarizing plate 132 is bonded to the second opposing substrate 220 of the liquid crystal display panel 200, which will be described later, by a light-transmitting adhesive layer 150. The adhesive layer 150 is, for example, OCA (Optical Clear Adhesive).

[0023] The first driver circuit 136 is provided on the main surface 110a of the first TFT substrate 110. The first driver circuit 136 supplies voltage to the scanning lines, signal lines, and common lines based on the color image signal supplied from the display control unit 400.

[0024] (LCD display panel) As shown in Figure 3, the liquid crystal display panel 200 is located on the back side (-Z side) of the color liquid crystal display panel 100 and is bonded to the color liquid crystal display panel 100 by an adhesive layer 150. The liquid crystal display panel 200 displays monochrome images.

[0025] In this embodiment, the liquid crystal display panel 200 is a transmissive transverse electric field type liquid crystal display panel using positive-type liquid crystal. The liquid crystal display panel 200 is actively matrix driven by a switching element 240, which will be described later. As shown in Figure 4, the liquid crystal display panel 200 has main pixels 202 arranged in a matrix in a rectangular display area 201. The main pixels 202 of the liquid crystal display panel 200 emit light to a plurality of subpixels 104 of the color liquid crystal display panel 100. The relationship between the main pixels 202 of the liquid crystal display panel 200 and the main pixels 102 of the color liquid crystal display panel 100 will be described later. Note that in Figure 4, the shape of the main pixels 202 of the liquid crystal display panel 200 is simplified.

[0026] As shown in Figure 3, the liquid crystal display panel 200 comprises a second TFT substrate 210, a second opposing substrate 220, a second liquid crystal 230, a third polarizing plate 232, and a second driver 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 provided on the second TFT substrate 210. In this embodiment, the first polarizing plate 132 of the color liquid crystal display panel 100 also serves as the polarizing plate on the light-emitting side of the liquid crystal display panel 200. Furthermore, the liquid crystal display panel 200 does not include a color filter or a black matrix.

[0027] The second TFT substrate 210 is, for example, a glass substrate. On the main surface 210a of the second TFT substrate 210 on the side facing the second liquid crystal 230, a plurality of scanning lines GL, a plurality of signal lines DL, a common line (not shown), a switching element 240 and pixel electrode 250 of the main pixel 202, a common electrode CE, an alignment film (not shown) for aligning the second liquid crystal 230, etc., are formed. The common line supplies a common potential to the common electrode CE that applies voltage to the second liquid crystal 230. The signal lines DL supply voltage to the pixel electrode 250 that applies voltage to the second liquid crystal 230 via the switching element 240. The scanning lines GL supply voltage to operate the switching element 240. A third polarizing plate 232 is provided on the main surface 210b of the second TFT substrate 210 opposite to the main surface 210a. The configuration of the scanning lines GL, pixel electrode 250, etc., will be described later.

[0028] The second opposing substrate 220 faces the second TFT substrate 210 and is bonded to the second TFT substrate 210 by a sealing material 238. The second opposing substrate 220 is, for example, 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 opposing substrate 220 that faces the second liquid crystal 230. An adhesive layer 150 is provided on the main surface 220b of the second opposing substrate 220 that is opposite to the main surface 220a. The second opposing substrate 220 is bonded to the color liquid crystal display panel 100 (first polarizing plate 132) via the adhesive layer 150.

[0029] The second liquid crystal 230 is sandwiched between the second TFT substrate 210 and the second opposing substrate 220. The second liquid crystal 230 is a positive-type (positive dielectric anisotropy) nematic liquid crystal. The second liquid crystal 230 is initially oriented in the +Y direction by an alignment film. In this embodiment, the +Y direction, which is the initial orientation direction of the positive-type second liquid crystal 230, corresponds to a predetermined first direction.

[0030] The second liquid crystal 230 rotates in a plane parallel to the main surface 210a of the second TFT substrate 210 when a voltage is applied. The rotation of the second liquid crystal 230 will be described later.

[0031] The third polarizing plate 232 is provided 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 orientation direction of the second liquid crystal 230. The transmission axis of the third polarizing plate 232 and the transmission axis of the first polarizing plate 132 of the color liquid crystal display panel 100 (the polarizing plate on the light-emitting side of the liquid crystal display panel 200) are perpendicular, and the liquid crystal display panel 200 operates in normally black mode.

[0032] The second driver circuit 236 is provided on the main surface 210a of the second TFT substrate 210. Based on signals supplied from the display control unit 400, the second driver circuit 236 supplies voltage to the scanning wiring GL, the signal wiring DL, and the common wiring.

[0033] Next, the configuration of the scanning wiring GL, signal wiring DL, main pixel 202, etc. will be explained with reference to Figures 4 to 11. Figure 5 is a plan view showing the scanning wiring GL, signal wiring DL, pixel electrode 250, etc. Figure 6 is a cross-sectional view of the switching element 240 shown in Figure 5, viewed by the arrow AA, and Figure 7 is a cross-sectional view of the contact hole CH shown in Figure 5, viewed by the arrow BB. Figure 8 is a plan view showing the pixel electrode 250. Note that in Figure 5, for ease of understanding, a part of the linear electrode 254 and the common electrode CE of the pixel electrode 250, which will be described later, are omitted. Also, in Figures 6 and 7, the hatching of the third insulating layer 278 is omitted. In Figure 8, the pixel electrode 250 is shown by a solid line.

[0034] As shown in Figures 4 and 5, the scanning wiring GL extends in a zigzag pattern in the X direction. The bending point P1 of the scanning wiring GL overlaps with the black matrix BM extending in the X direction of the color liquid crystal display panel 100, as will be described later. As shown in Figure 7, the scanning wiring GL is formed on the main surface 210a of the second TFT substrate 210 and is covered by the first insulating layer 272. The scanning wiring GL is formed from a metal such as aluminum (Al) or molybdenum (Mo). In this embodiment, the X direction in which the scanning wiring GL extends corresponds to a predetermined second direction.

[0035] As shown in Figures 4 and 5, the signal wiring DL extends in the Y direction and is bent along the linear electrode 254 of the pixel electrode 250. As shown in Figure 6, the signal wiring DL is formed on the first insulating layer 272 and covered by the second insulating layer 274. The signal wiring DL is also formed from a metal such as aluminum (Al) or molybdenum (Mo).

[0036] The common electrode CE is formed on an organic interlayer film 276 that is formed on the second insulating layer 274, as shown in Figures 6 and 7. The common electrode CE is formed from, for example, ITO (Indium Tin Oxide). The common electrode CE is covered by a third insulating layer 278.

[0037] The switching element 240 is located near the intersection of the scanning trace GL and the signal trace DL. As shown in Figures 5 and 6, the switching element 240 has a gate electrode 242, a semiconductor layer 244, a source electrode 246, and a drain electrode 248. The switching element 240 is, for example, a TFT element.

[0038] The gate electrode 242 is formed integrally with the scanning wiring GL on the main surface 210a of the second TFT substrate 210. The gate electrode 242 is covered by the first insulating layer 272, similar to the scanning wiring GL. The semiconductor layer 244 is provided on top of the gate electrode 242 in an island-like manner via the first insulating layer 272. The semiconductor layer 244 is formed from, for example, amorphous silicon. The source electrode 246 is formed on top of the semiconductor layer 244, branching from the signal wiring DL. The drain electrode 248 extends from above the semiconductor layer 244 along the scanning wiring GL. As shown in Figure 7, the drain electrode 248 is connected to the main electrode 252 of the pixel electrode 250, which will be described later, via a contact hole CH that penetrates the third insulating layer 278, the organic interlayer film 276, and the second insulating layer 274. The source electrode 246 and the drain electrode 248 are formed from a metal such as aluminum (Al) or molybdenum (Mo), similar to the signal wiring DL. Furthermore, the semiconductor layer 244, the source electrode 246, and the drain electrode 248 on the semiconductor layer 244 are covered by a second insulating layer 274, as shown in Figure 6.

[0039] As shown in Figures 6 and 7, the first insulating layer 272 covers the scanning wiring GL and the gate electrode 242 of the switching element 240. The second insulating layer 274 covers the semiconductor layer 244 of the switching element 240, the source electrode 246, the drain electrode 248 on the semiconductor layer 244, and the first insulating layer 272. The organic interlayer film 276 is formed from a photosensitive resin on top of the second insulating layer 274. The third insulating layer 278 covers the common electrode CE and the organic interlayer film 276. The first insulating layer 272, the second insulating layer 274, and the third insulating layer 278 are formed from silicon nitride (SiNx), silicon oxide (SiOx), etc.

[0040] The pixel electrode 250 is formed on the third insulating layer 278, as shown in Figures 6 and 7. The pixel electrode 250 is formed from, for example, ITO. The pixel electrode 250 also has a main electrode 252 and a linear electrode 254, as shown in Figures 5 and 8.

[0041] The main electrode 252 is mounted on the scanning wiring GL and bent along the scanning wiring GL. Therefore, the main electrode 252 has the same bending point P1 as the bending point P1 of the scanning wiring GL.

[0042] The linear electrode 254 branches off from the main electrode 252 and extends in the +Y direction or the -Y direction. The linear electrode 254 has a first inclined section 254a and a second inclined section 254b. In the first inclined section 254a, the long sides 255a and 255b of the linear electrode 254 are inclined at an acute angle clockwise with respect to the +Y direction, and the first inclined section 254a is inclined at an acute angle clockwise with respect to the +Y direction. In the second inclined section 254b, the long sides 255a and 255b of the linear electrode 254 are inclined at an acute angle counterclockwise with respect to the +Y direction, and the second inclined section 254b is inclined at an acute angle counterclockwise with respect to the +Y direction. The linear electrode 254 extends in the +Y direction or the -Y direction by repeating the first inclined section 254a and the second inclined section 254b. The linear electrodes 254 are arranged parallel to each other and at equal intervals in the X direction.

[0043] As shown in Figure 8, the external shape of the pixel electrode 250 is bent along the scanning wiring GL and has an asymmetric V-shape with a protrusion 256 and a notch 258 on the +Y side and the -Y side. The protrusion 256 and the notch 258 are provided, as will be described later, at the boundary 290 of adjacent main pixels 202 in the Y direction, in order to make the inclination direction of the boundary line 292 between adjacent main pixels 202 in the Y direction the same as the inclination direction of the linear electrode 254 in the Y direction. Here, in this specification, "same inclination direction" means that they are inclined at an acute angle in the same direction (clockwise or counterclockwise) with respect to a predetermined first direction. For example, if both the boundary line 292 and the linear electrode 254 are inclined at an acute angle clockwise with respect to the +Y direction, then the inclination direction of the boundary line 292 and the linear electrode 254 is the same. In this embodiment, the external shape of the pixel electrode 250 is the same as the shape of the main pixel 202.

[0044] The external shape patterns of the pixel electrodes 250 (the patterns of the linear electrodes 254) are divided into patterns A to D as shown in Figure 8, with each pair of patterns A to D repeating in the X direction. On the other hand, in the Y direction, pixel electrodes 250 with the same patterns are arranged. Patterns A and C, and patterns B and D are rotationally symmetric with respect to the X axis.

[0045] In this embodiment, at the boundary portion 290 of adjacent main pixels 202 in the Y direction, the inclination direction of the boundary line 292 between adjacent main pixels 202 with respect to the +Y direction (i.e., the initial orientation direction of the positive-type second liquid crystal 230) and the inclination direction of the linear electrode 254 with respect to the +Y direction are the same. Here, the inclination direction of the boundary line 292 and the inclination direction of the linear electrode 254 will be explained using the portion 280 shown in Figure 8 as an example, with reference to Figure 9.

[0046] As shown in Figure 9, when the linear electrode 254 at the boundary portion 290 is a first inclined portion 254a that is inclined at an acute angle clockwise with respect to the +Y direction, the boundary line 292 is inclined at an acute angle clockwise with respect to the +Y direction, similar to the first inclined portion 254a. Also, when the linear electrode 254 at the boundary portion 290 is a second inclined portion 254b that is inclined at an acute angle counterclockwise with respect to the +Y direction, the boundary line 292 is inclined at an acute angle counterclockwise with respect to the +Y direction, similar to the second inclined portion 254b, due to the provision of a protruding portion 256 and a notch 258. In other parts of the pixel electrode 250, similar to portion 280, the inclination direction of the boundary line 292 with respect to the +Y direction and the inclination direction of the linear electrode 254 with respect to the +Y direction are the same. Furthermore, since the linear electrodes 254 are arranged parallel to each other in the X direction, at the boundary 290 of adjacent principal pixels 202 in the X direction, the slope direction of the boundary line 292 between adjacent principal pixels 202 in the X direction is the same as the slope direction of the linear electrodes 254.

[0047] In this embodiment, the inclination direction of the boundary line 292 and the inclination direction of the linear electrode 254 are the same. Furthermore, the tip portion 254c of the linear electrode 254 has a shape like a chisel edge, as shown in Figure 9. The inclined surface (bevel) of the tip portion 254c of the linear electrode 254, i.e., the end edge 255c of the linear electrode 254, is inclined at an acute angle in a clockwise or counterclockwise direction with respect to the +Y direction, and the inclination direction of the end edge 255c of the linear electrode 254 and the boundary line 292 with respect to the +Y direction are the same. As a result, as shown in Figure 10, an electric field (electric field direction E) is generated at the boundary portion 290 between adjacent main pixels 202, causing the liquid crystal molecules 230M at the boundary portion 290 to rotate in the same direction as the liquid crystal molecules 230M within the main pixels 202 (for example, clockwise with respect to the +Y direction). Therefore, by rotating the liquid crystal molecules 230M in the main pixel 202 at the interface where they meet the edge region of the boundary 290 in the same direction, the generation of discrination lines can be suppressed. At the same time, the generation of dark lines can be suppressed by rotating the liquid crystal molecules 230M in the bulk region of the boundary 290 in the same direction. Since the generation of discrination lines and dark lines can be suppressed, the transmittance of the liquid crystal display panel 200 is improved.

[0048] Referring to Figures 11 and 12, the rotation of the liquid crystal molecules 230M and the transmittance of the liquid crystal display panel 200 will be explained in more detail. Figure 11 shows the initial orientation state of the liquid crystal molecules 230M within the main pixel 202 and the state in which the liquid crystal molecules 230M have rotated due to the electric field generated by the linear electrode 254. The electric field direction E1 shown in Figure 11 indicates the direction of the electric field generated by the linear electrode 254 within the main pixel 202. The angle θ1 shown in Figure 11 indicates the angle at which the liquid crystal molecules 230M within the main pixel 202 rotate due to the electric field. Figure 12 shows the initial orientation state of the liquid crystal molecules 230M at the boundary 290 and the state in which the liquid crystal molecules 230M have rotated due to the electric field generated by the linear electrode 254. The electric field direction E2 shown in Figure 12 indicates the direction of the electric field generated at the boundary 290. The angle θ2 indicates the angle at which the liquid crystal molecules 230M at the boundary 290 rotate due to the electric field.

[0049] Generally, when liquid crystal molecules are uniformly oriented in one direction between two polarizing plates with orthogonal polarization axes, the intensity of light transmitted through the upper and lower polarizing plates is expressed by the following equation (1). I = I0 × sin 2 (2×θ)×sin 2 (πΔnd / λ) (1) Here, I represents the intensity of emitted light, I0 represents the intensity of incident light, θ represents the angle between the polarization axis of the polarizer and the long axis of the liquid crystal, Δn represents the refractive index anisotropy of the liquid crystal molecules, d represents the thickness of the gap in which the liquid crystal is enclosed, and λ represents the wavelength of light. From equation (1), the intensity of emitted light is maximized when θ = 45°. Therefore, the electric field direction E1 formed by the linear electrode 254 in the main pixel 202 and the orientation direction of the second liquid crystal 230 are set according to equation (1) such that the intensity of emitted light (i.e., the transmittance of the liquid crystal display panel 200) is maximized when the liquid crystal molecules 230M rotate.

[0050] In this embodiment, the inclination direction of the boundary line 292 is the same as the inclination direction of the linear electrode 254, and the inclination direction of the boundary line 292 is the same as the inclination direction of the end edge 255c of the linear electrode 254. As shown in Figures 11 and 12, the direction of the electric field at the boundary 290 (electric field direction E2) approaches the direction of the electric field within the main pixel 202 (electric field direction E1). As a result, the liquid crystal molecules 230M in the boundary 290 rotate continuously with the liquid crystal molecules 230M in the main pixel 202, so the transmittance of light passing through the boundary 290 approaches the transmittance of light passing through the main pixel 202. Therefore, the decrease in the transmittance of light passing through the boundary 290 can be suppressed, and the transmittance of the liquid crystal display panel 200 can be improved.

[0051] On the other hand, for example, if the inclination direction of the boundary line 292 and the inclination direction of the linear electrode 254 are different (hereinafter referred to as Comparative Example 1), the liquid crystal molecules 230M at the boundary portion 290 between adjacent main pixels 202 and the liquid crystal molecules 230M within the main pixels 202 may rotate in different directions. In Comparative Example 1, for example, as shown in Figure 13, the liquid crystal molecules 230M at the boundary portion 290 between adjacent main pixels 202 rotate clockwise with respect to the +Y direction, while the liquid crystal molecules 230M within the main pixels 202 rotate counterclockwise with respect to the +Y direction. As a result, disclination lines are generated between the interface where the adjacent main pixels 202 and the edge region of the boundary portion 290 of Comparative Example 1 meet, and the transmittance of the liquid crystal display panel having the configuration of Comparative Example 1 decreases.

[0052] As described above, since the slope direction of the boundary line 292, the slope direction of the linear electrode 254, and the slope direction of the edge 255c of the linear electrode 254 are the same, the rotation of the liquid crystal molecules 230M between adjacent main pixels 202 can be controlled to suppress the generation of discrimination lines and dark lines, thereby improving the transmittance of the liquid crystal display panel 200.

[0053] Next, the relationship between the main pixels 202 of the liquid crystal display panel 200 and the main pixels 102 of the color liquid crystal display panel 100 will be described. In this embodiment, the main pixels 202 of the liquid crystal display panel 200 have a bent shape along the scanning wiring GL. Furthermore, the main pixels 202 of the liquid crystal display panel 200 emit light to a plurality of subpixels 104 of the color liquid crystal display panel 100. Therefore, it is preferable that the display area 201 of the liquid crystal display panel 200 is wider than the display area 101 of the color liquid crystal display panel 100.

[0054] Furthermore, as shown in Figure 14, the bend point P1 of the scanning wiring GL of the liquid crystal display panel 200 (i.e., the bend point of the main electrode 252) coincides with the black matrix BM of the color liquid crystal display panel 100, which defines the main pixel 102 of the color liquid crystal display panel 100 and extends in the X direction. Also, the V-shaped bend point P2 in the main pixel 202 of the liquid crystal display panel 200 coincides with the black matrix BM of the color liquid crystal display panel 100, which defines the main pixel 102 of the color liquid crystal display panel 100 and extends in the X direction. As a result, the color liquid crystal display panel 100 can utilize the light emitted from the liquid crystal display panel 200 with high efficiency. Note that in Figure 14, the black matrix BM of the color liquid crystal display panel 100 is exaggerated for ease of understanding.

[0055] (Backlight) As shown in Figure 1, the backlight 300 is located on the back side (-Z side) of the liquid crystal display panel 200. The backlight 300 is, for example, a direct-lit backlight. The backlight 300 includes white LED (light-emitting diode) elements, a reflective sheet, a diffusion sheet, etc. (none of which are shown).

[0056] (Display Control Unit) The display control unit 400 controls the display of the color liquid crystal display panel 100 and the liquid crystal display panel 200. As shown in Figure 15, the display control unit 400 includes an image data distribution unit 410, a first image signal generation unit 420, a second image luminance signal generation unit 430, and a second image signal generation unit 440.

[0057] The image data distribution unit 410 distributes the input image data to the first image signal generation unit 420 and the second image luminance signal generation unit 430.

[0058] The first image signal generation unit 420 generates a color image to be displayed on the color liquid crystal display panel 100 from the input image data distributed from the image data distribution unit 410. Specifically, the first grayscale conversion unit 422 of the first image signal generation unit 420 performs grayscale conversion to convert the distributed input image data into color image data having brightness-grayscale characteristics suitable for the color liquid crystal display panel 100. For data conversion, for example, a lookup table with pre-set input / output relationships is used. The first image signal generation unit 420 transmits a color image signal representing the generated color image to the first driver circuit 136 of the color liquid crystal display panel 100.

[0059] The second image luminance signal generation unit 430 generates a luminance signal from the input image data distributed from the image data distribution unit 410 to generate a monochrome image to be displayed on the liquid crystal display panel 200. The second image luminance signal generation unit 430 determines the luminance level of one main pixel 202 of the liquid crystal display panel 200 from the average value, frequency value, minimum value, maximum value, etc. of the gradation values ​​of multiple subpixels 104 of the color liquid crystal display panel 100 into which light emitted from one main pixel 202 of the liquid crystal display panel 200 is incident. The determined luminance level may also be a gradation value. The second image luminance signal generation unit 430 transmits a luminance signal representing the determined luminance level to the second image signal generation unit 440.

[0060] The second image signal generation unit 440 generates a monochrome image to be displayed on the liquid crystal display panel 200 based on the luminance signal transmitted from the second image luminance signal generation unit 430. The second image signal generation unit 440 generates a monochrome image that has been subjected to, for example, averaging and grayscale conversion. Specifically, the calculation unit 442 of the second image signal generation unit 440 averages the luminance levels of principal pixels 202 located within a predetermined distance from the principal pixel 202 of interest, for example, by a weighted average based on the distance from the principal pixel 202 of interest. This allows the second image signal generation unit 440 to generate a monochrome image with blurred edges. Furthermore, the second grayscale conversion unit 444 of the second image signal generation unit 440 generates monochrome image data having luminance-grayscale characteristics suitable for the liquid crystal display panel 200. The configuration of the second grayscale conversion unit 444 is the same as that of the first grayscale conversion unit 422 of the first image signal generation unit 420.

[0061] The monochrome image signal transmitted to the liquid crystal display panel 200 is delayed relative to the color image signal transmitted to the color liquid crystal display panel 100 due to the calculation and averaging of the brightness level performed by the second image brightness signal generation unit 430. Therefore, the display control unit 400 is equipped with a synchronization circuit (not shown) to synchronize the output of the monochrome image signal and the color image signal. The synchronization circuit causes a monochrome image corresponding to the color image on the color liquid crystal display panel 100 to be displayed on the liquid crystal display panel 200, so that the appropriate color image is displayed on the liquid crystal display device 10.

[0062] The display control unit 400 consists of a CPU (Central Processing Unit), memory, and the like. The functions of the display control unit 400 are realized, for example, by the CPU executing a program stored in memory.

[0063] As described above, in the liquid crystal display panel 200, the slope direction of the boundary line 292, the slope direction of the linear electrode 254, and the slope direction of the edge 255c of the linear electrode 254 are the same. Therefore, the rotation of liquid crystal molecules 230M between adjacent main pixels 202 can be controlled to suppress the generation of discrination lines and dark lines. Since the generation of discrination lines and dark lines can be suppressed, the transmittance of the liquid crystal display panel 200 can be improved. Furthermore, since the transmittance of the liquid crystal display panel 200 is improved, the transmittance of the liquid crystal display device 10 is also improved.

[0064] <Embodiment 2> In Embodiment 1, the second liquid crystal 230 of the liquid crystal display panel 200 is a positive-type nematic liquid crystal. The second liquid crystal 230 of the liquid crystal display panel 200 may also be a negative-type (negative dielectric anisotropy) nematic liquid crystal. Here, the initial orientation direction of the second liquid crystal 230 and the rotation of the second liquid crystal 230 at the boundary portion 290 will be described. The other configurations of this embodiment are the same as in Embodiment 1.

[0065] The second liquid crystal 230, which is a negative-type nematic liquid crystal, is initially oriented in the +X direction. In this embodiment, the +Y direction, which is perpendicular to the +X direction, which is the initial orientation direction of the negative-type second liquid crystal 230, corresponds to a predetermined first direction.

[0066] In this embodiment as well, similar to Embodiment 1, at the boundary portion 290 of adjacent main pixels 202 in the Y direction, the inclination direction of the boundary line 292 between adjacent main pixels 202 with respect to the +Y direction (i.e., the direction perpendicular to the initial orientation direction of the negative-type second liquid crystal 230) and the inclination direction of the linear electrode 254 with respect to the +Y direction are the same. Also, the inclination direction of the end edge 255c of the linear electrode 254 with respect to the +Y direction is the same as the inclination direction of the boundary line 292 with respect to the +Y direction. As a result, as shown in Figure 16, an electric field (electric field direction E) is generated at the boundary portion 290 between adjacent main pixels 202, which rotates the liquid crystal molecules 230M at the boundary portion 290 between adjacent main pixels 202 in the same direction as the liquid crystal molecules 230M within the main pixels 202 (for example, clockwise with respect to the +Y direction). Therefore, similar to Embodiment 1, the rotation of liquid crystal molecules 230M between adjacent main pixels 202 can be controlled to suppress the generation of discration lines and dark lines, thereby improving the transmittance of the liquid crystal display panel 200.

[0067] Figure 17 shows the initial orientation state of the liquid crystal molecules 230M within the main pixel 202 and the state after the liquid crystal molecules 230M have been rotated by the electric field generated by the linear electrode 254. The electric field direction E3 shown in Figure 17 indicates the direction of the electric field generated by the linear electrode 254 within the main pixel 202. The angle θ3 indicates the angle at which the liquid crystal molecules 230M within the main pixel 202 are rotated by the electric field. Figure 18 shows the initial orientation state of the liquid crystal molecules 230M at the boundary 290 and the state after the liquid crystal molecules 230M have been rotated by the electric field generated by the linear electrode 254. The electric field direction E4 shown in Figure 18 indicates the direction of the electric field generated at the boundary 290. The angle θ4 indicates the angle at which the liquid crystal molecules 230M at the boundary 290 are rotated by the electric field.

[0068] In this embodiment as well, the inclination direction of the boundary line 292 and the inclination direction of the linear electrode 254 are the same, and the inclination direction of the boundary line 292 and the inclination direction of the end edge 255c of the linear electrode 254 are the same. As shown in Figures 17 and 18, the direction of the electric field at the boundary 290 (electric field direction E4) approaches the direction of the electric field within the main pixel 202 (electric field direction E3), and the liquid crystal molecules 230M at the boundary 290 rotate continuously with the liquid crystal molecules 230M in the main pixel 202. Therefore, in this embodiment as well, similar to Embodiment 1, the decrease in the transmittance of light passing through the boundary 290 can be suppressed, and the transmittance of the liquid crystal display panel 200 can be improved.

[0069] On the other hand, when the inclination direction of the boundary line 292 and the inclination direction of the linear electrode 254 are different (hereinafter referred to as Comparative Example 2), the liquid crystal molecules 230M at the boundary portion 290 between adjacent main pixels 202 and the liquid crystal molecules 230M within the main pixels 202 may rotate in different directions. In Comparative Example 2, for example, as shown in Figure 19, the liquid crystal molecules 230M at the boundary portion 290 between adjacent main pixels 202 rotate clockwise with respect to the +Y direction, while the liquid crystal molecules 230M within the main pixels 202 rotate counterclockwise with respect to the +Y direction. As a result, disclination lines are generated between the interface where the adjacent main pixels 202 and the edge region of the boundary portion 290 of Comparative Example 2 meet, and the transmittance of the liquid crystal display panel having the configuration of Comparative Example 2 decreases.

[0070] As described above, even when using a negative-type second liquid crystal 230, the rotation of liquid crystal molecules 230M between adjacent main pixels 202 can be controlled to suppress the generation of discration lines and dark lines, thereby improving the transmittance of the liquid crystal display panel 200.

[0071] <Variation> While embodiments have been described above, this disclosure can be modified in various ways without departing from its essence.

[0072] For example, in this embodiment, the color liquid crystal display panel 100 is a lateral field type liquid crystal display panel using positive-type liquid crystal, but the method of the color liquid crystal display panel 100 may be VA (Vertical Alignment) mode, TN (Twisted Nematic) mode, etc. Also, the display area 101 of the color liquid crystal display panel 100 and the display area 201 of the liquid crystal display panel 200 are not limited to a rectangular shape, but may be non-rectangular in shape.

[0073] Furthermore, the liquid crystal display panel 200 may display a monochrome image on its own by providing a polarizing plate (a polarizing plate on the light-emitting side) on the main surface 220b of the second opposing substrate 220. In addition, the liquid crystal display panel 200 may display a color image by providing a color filter and a black matrix on the main surface 220a of the second opposing substrate 220.

[0074] In Embodiment 1, the initial alignment direction of the second liquid crystal 230 (positive-type liquid crystal) is in the +Y direction, but the initial alignment direction of the second liquid crystal 230 (positive-type liquid crystal) may be in the -Y direction. Also, in Embodiment 2, the initial alignment direction of the second liquid crystal 230 (negative-type liquid crystal) is in the +X direction, but the initial alignment direction of the second liquid crystal 230 (negative-type liquid crystal) may be in the -X direction.

[0075] In this embodiment, the linear electrode 254 of the liquid crystal display panel 200 is formed from a first inclined portion 254a that is inclined at an acute angle clockwise with respect to the +Y direction and a second inclined portion 254b that is inclined at an acute angle counterclockwise with respect to the +Y direction. The linear electrode 254 only needs to be inclined with respect to a predetermined first direction (+Y direction). For example, the linear electrode 254 may be formed from only the first inclined portion 254a.

[0076] The pattern of the outline shape of the main pixels 202 of the liquid crystal display panel 200 (the pattern of the linear electrodes 254) is not limited to patterns A to D. The pattern of the outline shape of the main pixels 202 (the pattern of the linear electrodes 254) is arbitrary as long as the inclination direction of the boundary line 292 between adjacent main pixels 202 in the +Y direction (a predetermined first direction) and the inclination direction of the linear electrodes 254 in the +Y direction are the same.

[0077] In Embodiment 1, the end edge 255c of the linear electrode 254 is straight. At the boundary 290, the end edge 255c of the linear electrode 254 only needs to be inclined in the same direction as the boundary line 292 and the linear electrode 254, and may be curved as shown in Figure 20. When the end edge 255c of the linear electrode 254 is curved, for example, the inclination direction of the tangent 294 to the end edge 255c with respect to the +Y direction is the same as the inclination direction of the boundary line 292 and the linear electrode 254 with respect to the +Y direction. Also, the tip portion 254c of the linear electrode 254 may be rounded.

[0078] In Embodiment 2 as well, the end edge 255c of the linear electrode 254 only needs to be inclined in the same direction as the boundary line 292 and the linear electrode 254, and may be curved. Also, the tip portion 254c of the linear electrode 254 may be rounded.

[0079] As shown in Figure 21, it is preferable that the inclination angle θ5 of the end edge 255c of the linear electrode 254 with respect to a predetermined first direction is greater than the inclination angle θ6 of the boundary line 292 with respect to a predetermined first direction. This brings the direction of the electric field at the boundary 290 (electric field direction E6) closer to the direction of the electric field within the main pixel 202 (electric field direction E5), thereby improving the transmittance of the liquid crystal display panel 200. Although Figure 21 shows the second liquid crystal 230 as a positive-type liquid crystal, the same applies when the second liquid crystal 230 is a negative-type liquid crystal.

[0080] In this embodiment, as shown in Figure 10, at the boundary 290, the extension line ExL of the long side 255a of the linear electrode 254 in one main pixel 202 coincides with the extension line ExL of the long side 255a of the linear electrode 254 in the other main pixel 202, and the extension line ExL of the long side 255b of the linear electrode 254 in one main pixel 202 coincides with the extension line ExL of the long side 255b of the linear electrode 254 in the other main pixel 202. At the boundary 290, the extension line ExL of the long side 255a of the linear electrode 254 in one main pixel 202 and the extension line ExL of the long side 255a of the linear electrode 254 in the other main pixel 202, and the extension line ExL of the long side 255b of the linear electrode 254 in one main pixel 202 and the extension line ExL of the long side 255b of the linear electrode 254 in the other main pixel 202 may be shifted in a direction perpendicular to a predetermined first direction (+Y direction) (X direction), as shown in Figure 22. As a result, the direction of the electric field at the boundary 290 (electric field direction E8) approaches the direction of the electric field within the main pixel 202 (electric field direction E7), thereby further improving the transmittance of the liquid crystal display panel 200. Note that although Figure 22 shows the second liquid crystal 230 as a positive-type liquid crystal, the same applies when the second liquid crystal 230 is a negative-type liquid crystal.

[0081] In this embodiment, the linear electrodes 254 of the liquid crystal display panel 200 are arranged at equal intervals in the X direction. When the linear electrodes 254 of one main pixel 202 and the linear electrodes 254 of the other main pixel 202 are parallel at the boundary 290 of adjacent main pixels 202, it is preferable that the distance L1 between the linear electrodes 254 of one main pixel 202 and the linear electrodes 254 of the other main pixel 202 is wider than the distance L2 between the linear electrodes 254 within the main pixels 202, as shown in Figure 23. This prevents excessive voltage from being applied to the second liquid crystal 230 located between the linear electrodes 254 at the boundary 290 when the liquid crystal display panel 200 is driven in reverse, thereby preventing the formation of dark lines between the linear electrodes 254 at the boundary 290.
