[0050] Reference will now be made in detail to embodiments of this disclosure, examples of which are illustrated in the accompanying drawings. The described progression of processing steps and / or operations is illustrative; however, the order of steps and / or operations is not limited to that described herein and can be varied as is known in the art, except for steps and / or operations that must occur in a specific order. The names of the various elements used in the following explanation may have been chosen merely for convenience of writing the specification and may therefore differ from the names used in actual products.

[0051] The advantages and features of this disclosure, as well as methods for achieving these advantages and features, will become clear from the following detailed description of exemplary embodiments in conjunction with the accompanying drawings. However, this disclosure is not limited to the exemplary embodiments disclosed herein, but will be implemented in various forms. Exemplary embodiments are provided by way of example only to enable those skilled in the art to fully understand the disclosure and scope of this disclosure.

[0052] The shapes, sizes, dimensions (e.g., length, width, height, thickness, radius, diameter, area, etc.), ratios, angles, and quantities of the elements shown in the accompanying drawings to describe exemplary embodiments of this disclosure are merely examples, and this disclosure is not limited thereto. Throughout the specification, the same reference numerals generally denote the same elements. Furthermore, in the following description of this disclosure, detailed descriptions of known related technologies may be omitted to avoid unnecessarily obscuring the subject matter of this disclosure.

[0053] The dimensions of the various components shown in the accompanying drawings, including size and thickness, are shown for ease of description, and this disclosure is not limited to the size and thickness of the components shown. However, it should be noted that the relative dimensions of the components shown in the various accompanying drawings, including relative size, position, and thickness, are part of this disclosure.

[0054] In this disclosure, when a first component (or region, layer, section, etc.) is described as being “on”, “connected”, or “attached to” a second component, it means that the first component may be directly connected to / attached to the second component, or that a third component may be disposed between them.

[0055] The same reference numerals denote the same parts. Additionally, in the drawings, the thickness, scale, and dimensions of parts are exaggerated for the purpose of effectively illustrating the technical content. The term "and / or" includes all one or more combinations that can be defined by the associated settings.

[0056] Terms such as "first" and "second" can be used to describe various components, but these components are not limited by the terms. These terms are used only for the purpose of distinguishing one component from another. For example, a first component can be referred to as a second component, and similarly, a second component can be referred to as a first component, as long as it does not depart from the scope of the implementation. Unless the context clearly specifies otherwise, the singular includes the plural.

[0057] Terms such as “below,” “under,” “above,” and “on top” are used to describe the relationships between the components shown in the accompanying drawings. These terms are relative concepts and are described relative to the directions indicated by the markings in the drawings.

[0058] When using terms such as “on top of,” “above,” “above,” “below,” “below,” “next to,” “under,” “near,” “close to,” “adjacent to,” “on the side of,” or “near” to describe the positional relationship between two parts, one or more parts may be located between the two parts, unless the term is used with the terms “exactly” or “directly.”

[0059] Spatially relative terms such as “below,” “under,” “below,” “lower,” “above,” “upper,” etc., may be used in this document to describe the relationship between one element or feature and another element or feature as illustrated in the figures. It should be understood that, in addition to the orientation shown in the figures, spatially relative terms may also include different orientations of elements in use or operation. For example, if an element in the figure is inverted, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the exemplary term “below” can include both lower and upper orientations. Similarly, the exemplary terms “above” or “above” can include both upper and lower orientations.

[0060] The word “exemplary” is used to indicate that something is an example or illustration. “Aspect” refers to an exemplary aspect. “Implementation,” “example,” “aspect,” etc., should not be construed as superior to or best of other implementations. Unless otherwise stated, implementation, example, exemplary implementation, aspect, etc., may refer to one or more implementations, one or more examples, one or more exemplary implementations, one or more aspects, etc. Furthermore, the word “may” encompasses all the meanings of the word “able to.”

[0061] When describing temporal relationships, for example, when using terms such as "after," "following," "next," and "before" to describe the temporal relationship of events, there may be cases where events are not consecutive, unless "immediately following" or "directly" is used.

[0062] It should be understood that terms such as “comprising,” “having,” “including,” “containing,” “constituting,” “made of,” “formed from,” “composed of” are intended to specify the presence of the features, numbers, steps, operations, components, parts or combinations thereof described in this specification, and do not preclude the possibility of the presence or addition of one or more other features, numbers, steps, operations, components, parts or combinations thereof.

[0063] The term "at least one" should be understood to include all possible combinations that can be suggested from one or more related projects. For example, "at least one of the first, second, or third projects" can mean each of the first, second, or third projects, and can also mean all possible combinations that can be suggested from two or more of the first, second, and third projects.

[0064] As used herein, the term "device" can refer to a display device that includes a display panel and a driver for driving the display panel. Examples of display devices may include light-emitting elements, etc. Additionally, examples of devices may include laptops, televisions, computer monitors, automotive devices, wearable devices, and automotive equipment devices, as well as assemblies of electronic devices (or equipment) or assemblies (or devices) that include light-emitting elements, etc., as complete products or end products, such as mobile electronic devices like smartphones or tablets, but embodiments of this disclosure are not limited thereto.

[0065] Features of the various embodiments of this disclosure may be partially or wholly adhered to or combined with each other, and may be interlocked and operated in various technical ways, and the embodiments may be performed independently or in association with each other.

[0066] Unless otherwise specified, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which the exemplary embodiments pertain. It will be further understood that terms, as defined in commonly used dictionaries, shall be interpreted as having a meaning consistent, for example, with their meaning in the context of the relevant art, and shall not be interpreted in an idealized or overly formal sense unless expressly defined herein.

[0067] In this disclosure, for ease of description, the source electrode and the drain electrode are distinguished from each other. However, the source electrode and the drain electrode are used interchangeably. A source electrode can be a drain electrode, and a drain electrode can be a source electrode. Furthermore, a source electrode in any aspect of this disclosure can be a drain electrode in another aspect of this disclosure, and a drain electrode in any aspect of this disclosure can be a source electrode in another aspect of this disclosure.

[0068] In the following description, embodiments of the present disclosure will be illustrated with reference to the accompanying drawings. In this disclosure, when adding reference numerals to elements in each drawing, it should be noted that whenever possible, the same reference numerals already used to denote elements in other drawings are used for that element. Furthermore, for ease of description, the scale of the constituent elements shown in the drawings may differ from the actual scale. That is, the scale of the constituent elements shown in the drawings should not be interpreted as the same as the scale shown in the drawings.

[0069] Figure 1This is a schematic diagram illustrating a stereoscopic image display device according to an exemplary embodiment of the present disclosure. Figure 2 This is a schematic cross-sectional view showing a stereoscopic image display device according to an exemplary embodiment of the present disclosure. Figure 3 This is a schematic diagram illustrating the configuration of a first substrate of a display panel according to an exemplary embodiment of the present disclosure. Figure 4 This is a diagram used to describe a method for realizing multiple views in a stereoscopic image display device.

[0070] Reference Figures 1 to 4 The stereoscopic image display device 10 can be implemented as a flat panel display device, such as a liquid crystal display (LCD) device, a field emission display (FED) device, a plasma display panel (PDP) device, or an organic light-emitting diode (OLED) display device. For ease of explanation, although examples in which the stereoscopic image display device 10 is implemented as an LCD device will be described primarily below, the exemplary embodiments of this disclosure are not limited thereto.

[0071] exist Figure 1 In this design, the X-axis can represent a direction parallel to the gate line, the Y-axis can represent a direction parallel to the data line, and the Z-axis can represent the height direction of the display device. However, this disclosure is not limited to this; for example, the Y-axis can represent a direction parallel to the gate line, the X-axis can represent a direction parallel to the data line, and the Z-axis can represent the height direction of the display device.

[0072] A stereoscopic image display device 10 according to an exemplary embodiment of the present disclosure may include a display panel 100, a backlight unit 200, and a viewing angle control device 300.

[0073] The display panel 100 can use multiple pixels P to display images. The display panel 100 may include a first substrate 110 and a second substrate 120, which are bonded together to face each other using a panel liquid crystal layer 130 interposed therebetween.

[0074] The first substrate 110 is a thin-film transistor array substrate including thin-film transistors, and may include multiple gate lines 111, multiple data lines 113, thin-film transistors (TFTs), and multiple pixels P. The multiple gate lines 111 and multiple data lines 113 may be arranged to intersect each other on the first substrate 110 to define multiple pixel regions.

[0075] A thin-film transistor (TFT) is formed in the transistor region of the pixel region and can be switched according to a gating signal supplied to gating line 111 to supply a data signal supplied to data line 113 to the pixel electrode PE. The TFT may include a gate electrode, a semiconductor layer, a source electrode, and a drain electrode. In one exemplary embodiment, the TFT may be implemented in a bottom gate structure where the gate electrode is located below the semiconductor layer, or in a top gate structure where the gate electrode is located above the semiconductor layer.

[0076] The semiconductor layer of a thin-film transistor can be formed from semiconductor materials, such as oxide semiconductors, amorphous semiconductors, or polycrystalline semiconductors, but is not limited to these.

[0077] Oxide semiconductor materials offer excellent leakage current prevention and relatively low manufacturing costs. Oxide semiconductors can be made from metal oxides such as zinc (Zn), indium (In), gallium (Ga), tin (Sn), and titanium (Ti), or combinations of metals and their oxides such as zinc (Zn), indium (In), gallium (Ga), tin (Sn), or titanium (Ti). Specifically, oxide semiconductors can include, but are not limited to, zinc oxide (ZnO), zinc tin oxide (ZTO), zinc indium oxide (ZIO), indium oxide (InO), titanium oxide (TiO), indium gallium zinc oxide (IGZO), indium zinc tin oxide (IZTO), indium zinc oxide (IZO), indium gallium tin oxide (IGTO), and indium gallium oxide (IGO).

[0078] Polycrystalline semiconductor materials exhibit high mobility due to the fast movement speed of charge carriers such as electrons and holes, resulting in low energy consumption and excellent reliability. Polycrystalline semiconductors can be made of polycrystalline silicon (poly-Si), but are not limited to this.

[0079] Amorphous semiconductor materials can be made of amorphous silicon (a-Si), but are not limited to this.

[0080] Multiple pixels P can display different colors. Multiple pixels P may include, but are not limited to, red pixels that display red, green pixels that display green, and blue pixels that display blue. For example, multiple pixels P may further include white pixels that display white. For example, a pixel comprising red, green, and blue pixels can be called a unit pixel. The aforementioned red, green, and blue pixels can also be called red sub-pixels, green sub-pixels, and blue sub-pixels. Furthermore, the multiple sub-pixels constituting a unit pixel can be modified in various ways in terms of color and configuration as needed.

[0081] For example, each of the plurality of sub-pixels can emit light with a different wavelength from each other. For example, the plurality of sub-pixels may include red, green, and blue sub-pixels, wherein the red, green, and blue sub-pixels may be arranged in a repeating manner. Alternatively, the plurality of sub-pixels may include red, green, blue, and white sub-pixels, wherein the red, green, blue, and white sub-pixels may be arranged in a repeating manner, or the red, green, blue, and white sub-pixels may be arranged in a quadrilateral pattern. For example, the red, blue, and green sub-pixels may be arranged sequentially along a row direction, or the red, blue, green, and white sub-pixels may be arranged sequentially along a row direction. However, in embodiments of this disclosure, the color type, arrangement type, and arrangement order of the sub-pixels are not limited and can be configured in various forms according to light-emitting characteristics, device lifetime, and device specifications.

[0082] Furthermore, depending on their light-emitting characteristics, sub-pixels can have different light-emitting areas. For example, a sub-pixel that emits light of a different color than the blue sub-pixel can have a different light-emitting area than the blue sub-pixel. For example, red, blue, and green sub-pixels, or red, blue, white, and green sub-pixels, can each have different light-emitting areas.

[0083] Each of the multiple pixels P may include a pixel electrode PE and a common electrode CE connected to a thin-film transistor TFT.

[0084] The pixel electrode PE can be connected to the source or drain electrode of the thin-film transistor TFT to generate an electric field in the liquid crystal layer 130 of the panel through a data signal supplied from the thin-film transistor TFT. The pixel electrode PE may include a plurality of first fingers F1. The plurality of first fingers F1 may protrude from the pixel electrode PE and extend to a common electrode CE disposed in the upper region of the pixel P.

[0085] The common electrode CE can drive the liquid crystal molecules of the panel liquid crystal layer 130 by generating an electric field together with the pixel electrode PE. The common electrode CE may include a plurality of second fingers F2. The plurality of second fingers F2 may protrude from the common electrode CE and extend close to the pixel electrode PE disposed in the lower region of the pixel P.

[0086] Each of the plurality of second fingers F2 can be disposed between adjacent first fingers F1. Therefore, a horizontal electric field can be generated between the pixel electrode PE and the common electrode CE. As shown in the figure, the common electrode CE is illustrated as comprising a plurality of second fingers F2, but is not necessarily limited thereto. For example, the common electrode CE can be formed to completely cover multiple pixel regions, and in this case, a vertical electric field can be generated between the pixel electrode PE and the common electrode CE.

[0087] The common electrode CE can be formed on the first substrate 110 together with the pixel electrode PE using a horizontal electric field driving method (such as in-plane switching (IPS) mode and edge field switching (FFS) mode). The common electrode CE can be formed on the second substrate 120 using a vertical electric field driving method (such as twisted nematic (TN) mode and vertical alignment (VA) mode). In addition to TN mode, VA mode, IPS mode and FFS mode, the liquid crystal mode of the display panel 100 can be implemented in any liquid crystal mode.

[0088] When the pixel electrode PE is formed in a curved shape, the pixel P can be formed as a multi-domain structure divided into a first domain do1 and a second domain do2. Since the multi-domain structure allows for different control of the liquid crystal orientation in the first domain do1 and the second domain do2, color shift and viewing angle can be improved. In the case of the multi-domain structure, the plurality of first fingers F1 and the plurality of second fingers F2 have a curved structure at the boundary between the first domain do1 and the second domain do2. Therefore, the first fingers F1 and the second fingers F2 can be arranged parallel to each other in a specific direction in either the first domain do1 or the second domain do2.

[0089] A set of view maps based on the number of views (or view regions) can be assigned to each of the multiple pixels P.

[0090] The second substrate 120 is a color filter array substrate including color filters, and may include a black matrix 124 and color filters 126.

[0091] The black matrix 124 may include a plurality of openings 122 that overlap with a plurality of pixels P respectively. Each of the plurality of openings 122 defines an opening region of pixel P and may have a smaller area than pixel P and may be formed in a different shape than pixel P. A portion of pixel P may be exposed through the openings 122. The black matrix 124 may be formed by mixing a black material into a base resin. The base resin may be at least one selected from epoxy resins, acrylate resins, siloxane resins, and polyimides, but is not limited thereto. In addition, the black material may be formed from any of black-based pigments or black-based dyes.

[0092] The color filter 126 can be disposed in the opening 122 not covered by the black matrix 124. The color filter 126 may include a red color filter, a green color filter, and a blue color filter.

[0093] The viewing angle can be adjusted by the arrangement of the color filter 126 and the black matrix 124 described above. Furthermore, considering factors such as flicker defects, the lifespan of the light-emitting element, and the viewing angle, the planar shape, area, and position of the light-emitting region can be determined, and black matrices 124 of various widths can be formed between the light-emitting regions. However, this disclosure is not limited thereto.

[0094] The display panel 100 can adjust the transmittance of light incident from the backlight unit 200 by supplying data signals from the panel driver to the corresponding pixel P to generate an electric field in the liquid crystal layer 130 of the panel. The display panel 100 can display an image according to the view mapping assigned to each pixel P.

[0095] The backlight unit 200 can be disposed on the rear surface of the display panel 100 to radiate light onto the display panel 100. The backlight unit 200 may include a light source 210, a light guide plate 220 for guiding light from the light source 210 toward the display panel 100, and an optical sheet 230 disposed on the light guide plate 220 to improve light efficiency. The backlight unit 200 can be implemented as a direct-type or edge-type backlight unit. The light source 210 of the backlight unit 200 may include one or two or more of a hot cathode fluorescent lamp (HCFL), a cold cathode fluorescent lamp (CCFL), an external electrode fluorescent lamp (EEFL), a light-emitting diode (LED), and an organic light-emitting diode (OLED).

[0096] However, the exemplary embodiments disclosed herein are not limited thereto, and the display panel 100 may be an OLED display panel, which does not require a separate light source 210 and includes OLED elements that can emit light on their own.

[0097] The viewing angle control device 300 may be disposed on the display panel 100 and may include a base film 310 and a plurality of optical path control members 320 disposed on the upper surface of the base film 310. For example, the base film may include a flexible polymer film. For example, the flexible polymer film may be made of any one of polyimide (PI), polyethylene terephthalate (PET), acrylonitrile-butadiene-styrene copolymer (ABS), polymethyl methacrylate (PMMA), polyethylene naphthalate (PEN), polycarbonate (PC), polyethersulfone (PES), polyarylate (PAR), polysulfone (PSF), cyclic olefin copolymer (COC), triacetyl cellulose (TAC), polyvinyl alcohol (PVA), and polystyrene (PS). However, this disclosure is not limited thereto. In one exemplary embodiment, the optical path control member 320 is described as a lens, but is not limited thereto.

[0098] For ease of description, the optical path control component 320 will be referred to as lens 320 in the following text.

[0099] Multiple lenses 320 can be positioned in the direction of light emission from the display panel (e.g., the Z-axis direction).

[0100] Multiple lenses 320 may be formed protrudingly from the upper surface of the base film 310 and may extend vertically. For example, the multiple lenses 320 may have a semi-circular or convex lens-shaped cross-section with a predetermined curvature. The multiple lenses 320 may have a semi-circular or convex lens-shaped cross-section with a predetermined curvature in a cross-section along a line extending along the X-axis.

[0101] The multiple lenses 320 can be biconvex lenses, but are not necessarily limited to this. The multiple lenses 320 can be implemented as switchable lenses. The multiple lenses 320 can be classified as tilting lenses and vertical lenses according to their angle with the set pixel P.

[0102] The viewing angle control device 300 can separate an image displayed on multiple pixels P into multiple views (or multiple viewing areas). The viewing angle control device 300 can form a viewing area at an optimal viewing distance by controlling light from the multiple pixels P. The viewing area can include multiple views (multiple views). Each of the multiple views can have a rhombus shape. Therefore, each of the multiple views can be referred to as a view rhombus. To allow the human eye (left and right eyes) to view different images, each of the multiple views can be formed with a width smaller than the distance between the human eyes.

[0103] The viewing angle control device 300 can use multiple lenses 320 to divide an image displayed on multiple pixels P into multiple views. The viewing angle control device 300 can divide the image displayed on the multiple pixels P included in the lenses 320 into multiple views corresponding to a view mapping, allowing a viewer to view a stereoscopic image in multiple viewing areas. At this time, due to the binocular parallax between the left-eye image LI perceived by the left eye and the right-eye image RI perceived by the right eye in a predetermined viewing area, the viewer can perceive a stereoscopic effect.

[0104] Figure 5 This is a diagram showing an example of a tilted lens. Figure 6 It is a graph used to describe vertical image distortion.

[0105] Reference Figure 5 and Figure 6In conventional stereoscopic image display devices, pixels P11 to P39 can be arranged vertically in a straight line, and multiple lenses 320 can be set at a predetermined angle in an inclined state. As described above, lenses set in an inclined state can be called tilted lenses. When a user moves vertically rather than horizontally while viewing a stereoscopic image displayed on a conventional stereoscopic image display device, the user can view different images depending on the viewing position.

[0106] like Figure 6 As shown, while viewing the image displayed by pixel P, the user's eye can move up and down along a vertical line VL. At this time, the user can view different view images while moving up and down along the vertical line VL.

[0107] When the user's eyes are positioned looking forward, the user can view the fourth view image through pixel P25 corresponding to the fourth view V4. When the user's eyes are positioned looking upwards or downwards relative to looking forward, the user can view the third view image through pixel P35 corresponding to the third view V3, or the fifth view image through pixel P15 corresponding to the fifth view V5. In conventional stereoscopic image display devices, there may be a problem of vertical image distortion caused by the vertical movement of the user's eyes.

[0108] Unlike conventional stereoscopic image display devices, a stereoscopic image display device 10 according to an exemplary embodiment of the present disclosure may have a plurality of lenses 320 arranged shifted along each horizontal line and a plurality of pixels arranged vertically aligned without tilting. When a user moves vertically rather than horizontally while viewing a stereoscopic image displayed on a stereoscopic image display device according to an exemplary embodiment of the present disclosure, the user may not even see different images when the viewing position changes.

[0109] Figure 7 This is a plan view showing pixels and lenses disposed in a stereoscopic image display device according to an exemplary embodiment.

[0110] Reference Figure 7 The stereoscopic image display device may include a plurality of pixels P (P11 to P99) and a black matrix 124 disposed around the plurality of pixels P. Figure 7 Only pixels 11 to 99 (P11 to P99) are shown, but the exemplary embodiments of this disclosure are not limited thereto. Pixels 11 to 99 (P11 to P99) can be repeatedly set in the X-axis direction and the Y-axis direction.

[0111] Multiple pixels P can include red pixels that display red, green pixels that display green, and blue pixels that display blue. That is, each of pixels P11 to P99 from the 11th to the 99th can be one of the red pixels that display red, the green pixels that display green, and the blue pixels that display blue.

[0112] A black matrix 124 can be disposed between multiple pixels P. The black matrix 124 may include multiple openings 122 that expose a portion of each of the multiple pixels P. Each of the multiple pixels P may include an opening region that overlaps with the multiple openings 122.

[0113] The black matrix 124 can be set to surround multiple pixels P and an opening 122, but is not limited to this.

[0114] The plurality of openings 122 may have a quadrilateral shape, but are not limited thereto. The plurality of openings 122 may have substantially the same shape. The plurality of openings 122 may have parallel long edges and parallel short edges of the same length. The plurality of openings 122 may have substantially perpendicular long edges and short edges. The plurality of openings 122 may be arranged at a first interval in a first direction D1. The plurality of openings 122 may be arranged at a second interval in a third direction D3.

[0115] Multiple openings 122 can be configured to be aligned in the X-axis direction (D1 direction) and the Y-axis direction (D3 direction), but are not limited thereto. For example, the openings 122 of a pixel P that are repeatedly configured in the X-axis direction (D1 direction) can have short edges that extend and are aligned in the X-axis direction (D1 direction) and long edges that extend and are aligned in the Y-axis direction (D3 direction).

[0116] The display panel 100 may include multiple horizontal lines H1, H2, H3, H4… The horizontal lines H1, H2, H3, H4… can have a 1×N array by aggregating N pixels P set along the X-axis direction (D1 direction) and 1 pixel P set along the Y-axis direction (D3 direction). For example, the first horizontal line H1 can have a 1×N array by aggregating multiple pixels P11, P12, P13,…, P1N set along the X-axis direction (D1 direction) and a single pixel P11 set along the Y-axis direction (D3 direction).

[0117] The number of horizontal lines H1, H2, H3, H4... and the number N of pixels P set on each of the horizontal lines H1, H2, H3, H4... can vary depending on the number of multiple views to be implemented by the stereoscopic image display device.

[0118] Horizontal lines H1, H2, H3, H4… can include multiple pixels P and multiple lenses 320. That is, each of the horizontal lines H1, H2, H3, H4… can include multiple pixels P and multiple lenses 320.

[0119] Lens 320 can be configured as multiple lenses. Lens 320 can be repeatedly configured in the X-axis direction (D1 direction) and in the Y-axis direction (D3 direction). Multiple lenses 320 can be individually configured in each horizontal line H1, H2, H3, H4… Furthermore, multiple lenses 320 can be repeatedly configured along the X-axis direction (D1 direction) in each horizontal line H1, H2, H3, H4…

[0120] Each of the lenses 320 may cover a plurality of openings 122 (or pixels P) arranged in the X-axis direction and may cover at least one opening 122 (or pixel P) in the Y-axis direction, but is not limited thereto. For example, each lens 320 may cover three or four openings 122 (or pixels P) arranged in the X-axis direction and may cover one opening 122 (or pixel P) in the Y-axis direction, but is not limited thereto.

[0121] For example, one of the multiple lenses 320 can cover the 11th pixel P11, the 12th pixel P12 and the 13th pixel P13, and another can cover a portion of the 21st pixel P21, a portion of the 24th pixel P24, the 22nd pixel P22 and the 23rd pixel P23.

[0122] All pixels P disposed on the display panel 100 can be covered by multiple lenses 320. Therefore, at least some of the horizontal lines H1, H2, H3, H4..., the lenses 320 disposed at the ends of one and the other sides in the X-axis direction can cover fewer than three pixels P in the X-axis direction.

[0123] In other words, in each of the horizontal lines H1, H2, H3, H4…, the lens 320, instead of being located at one end on the other side of the X-axis, can cover three or four openings 122 (or pixels P) located in the X-axis direction. Furthermore, in at least some of the horizontal lines H1, H2, H3, H4…, the lens 320 located at one end on the other side of the X-axis can cover fewer than three pixels P in the X-axis direction.

[0124] Multiple lenses 320 repeatedly arranged in the X-axis direction (D1 direction) can be aligned. Adjacent lenses 320 in the Y-axis direction (D3 direction) can be shifted in the X-axis direction (D1 direction). Adjacent lenses 320 in the Y-axis direction (D3 direction) can be shifted by a first distance PSV in the X-axis direction (D1 direction). Therefore, the cross-section of the lens 320 along the X-axis direction can be exposed.

[0125] When a lens 320 in each of the horizontal lines H1, H2, ... is positioned offset from a first distance PSV in the first direction D1, multiple lenses 320 can be repeatedly positioned in the second direction D2. Here, the second direction D2 can be a direction forming a predetermined angle with both the X-axis direction (D1 direction) and the Y-axis direction (D3 direction). The second direction D2 can be the direction between the X-axis direction (D1 direction) and the Y-axis direction (D3 direction). For example, the second direction D2 can be substantially parallel to the virtual line D2L connecting the center of the lens 320 positioned on the first horizontal line H1 and the center of the lens 320 adjacent to that lens 320 and positioned on the second horizontal line H2 in the third direction D3.

[0126] Lenses 320 set on each of the horizontal lines H1, H2... can be separated and repeatedly set along the D1 direction. Lenses 320 set on different horizontal lines H1, H2... can be separated and repeatedly set along the D2 direction.

[0127] The center of the lens 320 disposed on the first horizontal line H1 and the center of the lens 320 adjacent to the lens 320 on the third horizontal line H2 on the third direction D3 can be set to be spaced apart by a first distance PSV in the first direction D1 and by the length of the distance P between them in the third direction D3. The second direction D2 can be a direction derived from the fact that the center of the lens 320 disposed on one horizontal line (e.g., H1) and the center of the lens 320 disposed on another horizontal line (e.g., H2) are spaced apart by a first distance PSV in the first direction D1, wherein the one horizontal line (e.g., H1) and the other horizontal line (e.g., H2) are adjacent to each other in the third direction D3.

[0128] exist Figure 7 In the text, the lens 320 set on each horizontal line H1, H2, H3, H4... has been described as being shifted in the D1 direction, but is not limited to this.

[0129] Specifically, lenses 320 positioned on adjacent horizontal lines H1, H2, H3, H4… can be aligned in the D3 direction without shifting in the D1 direction. For example, lenses 320 positioned on the first horizontal line H1 and the second horizontal line H2 can be aligned in the D3 direction without shifting in the D1 direction. Lenses 320 positioned on the third horizontal line H3 and the fourth horizontal line H4 can be aligned in the D3 direction without shifting in the D1 direction. In this case, lenses 320 positioned on the first horizontal line H1 and the second horizontal line H2 can be shifted in the D1 direction relative to lenses 320 positioned on the third horizontal line H3 and the fourth horizontal line H4. That is, horizontal lines H1, H2, H3, H4… can be aligned by grouping them into two or more groups and shifted in the D1 direction on different groups of horizontal lines H1, H2, H3, H4…

[0130] Multiple lenses 320 may be arranged parallel to an edge (e.g., the long edge of opening 122). A display device according to an exemplary embodiment of the present disclosure may prevent vertical image distortion by including multiple lenses 320 that are misaligned in a second direction D2 with pixels P (or opening 122) aligned and repeatedly arranged in a third direction D3.

[0131] The user's eye can move up and down along a vertical line VL on each lens 320 while viewing the image displayed by pixel P. The user can move up and down along the vertical line VL while viewing only the image corresponding to one pixel P on each lens 320. Therefore, even when the user's eye moves vertically, the stereoscopic image display device according to an exemplary embodiment of this disclosure can prevent vertical image distortion.

[0132] The spacing width W1 of each of the multiple lenses 320 can be determined based on the number of multiple views and the pixel size, which will be implemented by the stereoscopic image display device. Pixels P that overlap with the multiple lenses 320 can be assigned view maps according to the multiple views, and view images can be displayed according to the assigned view maps.

[0133] According to an exemplary embodiment of the present disclosure, a plurality of pixels P can be grouped based on a cell U having an M×N array, in which N (N is a natural number of 1 or greater) pixels P are clustered on a first direction D1 and M (M is a natural number of 1 or greater) pixels P are clustered on a second direction D2 intersecting the first direction D1.

[0134] The display panel 100 may include multiple units that can vary according to the combination and grouping of pixels P. For example, the display panel 100 may include unit a, unit b, unit c, and unit e.

[0135] The a-th unit Ua may have a 1×3 array that aggregates three pixels P consecutively disposed in the first direction D1 and one pixel P disposed in the second direction D2. For example, the a-th unit Ua may include pixels P17, P18 and P19 from the 17th to the 19th, pixels P27, P28 and P29 from the 27th to the 29th, or pixels P37, P38 and P39 from the 37th to the 39th.

[0136] The e-th unit Ue can have a 3×1 array of one pixel P disposed on the first direction D1 and three pixels P disposed on the second direction D2. For example, the e-th unit Ue can include the 17th, 27th and 37th pixels P17, P27 and P37, the 18th, 28th and 38th pixels P18, P28 and P39, or the 19th, 29th and 39th pixels P19, P29 and P39.

[0137] The b-th unit Ub can have a 3×3 array, in which three pixels P are consecutively arranged in the first direction D1 and three pixels P are consecutively arranged in the second direction D2. For example, the b-th unit Ub can include pixels P17, P18, P19, P27, P28, P29, P37, P38 and P39, which are pixels 17 to 19, 27 to 29 and 37 to 39.

[0138] Unit b Ub may include unit a Ua and unit e Ue. A single unit b Ub may include three units a Ua and three units e Ue.

[0139] View mappings can be assigned to pixels P11, P12, P13, P21, P22, P23, P31, P32 and P33, P14, P15, P16, P24, P25, P26, P34, P35 and P36 or P17, P18, P19, P27, P28, P29, P37, P38 and P39 included in unit b Ub based on the number of views. A view mapping can be set to the number of pixels P included in unit b Ub, for example, 9 views. Pixels P included in unit b Ub can display images used for different views.

[0140] The c-th unit Uc can have a 3×9 array of 9 pixels P consecutively arranged in the first direction D1 and 3 pixels P consecutively arranged in the second direction D2. For example, the c-th unit Uc can include pixels P11 to 19, P21 to 29, and P31 to 39, which are pixels 11 to 19, 21 to 29, and 31 to 39, respectively.

[0141] As shown in the figure, the c-th unit Uc includes three horizontal lines, but the exemplary embodiments of this disclosure are not limited to this. The c-th unit Uc may include multiple horizontal lines.

[0142] The first distance PSV can be determined based on the size of pixel P. For example, the first distance PSV can correspond to 1 / Q of the horizontal length PS of pixel P (where Q is a natural number). Q can indicate the number of horizontal lines H1, H2, and H3 included in the c-th unit Uc. For example, when the c-th unit Uc includes three horizontal lines H1, H2, and H3, the first distance PSV can correspond to 1 / 3 of the horizontal length PS of pixel P. Furthermore, the horizontal length PS of pixel P can include both the opening region of pixel P that overlaps with the opening 122 and the non-opening region covered by the black matrix 124. The horizontal length PS of pixel P can be substantially the same as the horizontal length between the center of one pixel P and the center of another adjacent pixel P.

[0143] The first pixel P11 of the first horizontal line H1 can correspond to the first view, and the first view image is displayed in the first viewing area corresponding to the first view. The first pixel P21 of the second horizontal line H2 can correspond to the second view, and the second view image is displayed in the second viewing area corresponding to the second view. The first pixel P31 of the third horizontal line H3 can correspond to the third view, and the third view image is displayed in the third viewing area corresponding to the third view.

[0144] The second pixels P12, P22, and P32 of each of the first to third horizontal lines H1, H2, and H3 can correspond to the fourth to sixth views, and the third pixels P13, P23, and P33 corresponding to each of the first to third horizontal lines H1, H2, and H3 can correspond to the seventh to ninth views.

[0145] According to an exemplary embodiment of this disclosure, a plurality of lenses 320 may be disposed on each of N horizontal lines H1, H2, H3, H4, ... and HN, and lenses 320 disposed on each of the horizontal lines H1, H2, H3, H4, ... and HN and adjacent to each other in the third direction D3 may be arranged to be shifted by a first distance PSV in the horizontal direction (D1 direction).

[0146] In other words, based on each of the plurality of lenses 320 arranged in the second direction D2, the pixel P disposed in each of the plurality of lenses 320 arranged in the second direction D2 can be regarded as being arranged by shifting a first distance PSV in the horizontal direction (D1 direction) in each lens 320.

[0147] For example, one of the lenses 320 positioned on the first horizontal line H1 covers pixels 11, 12, and 13, P11, P12, and P13, and another lens 320 positioned on the second horizontal line H2 covers a portion of pixel 21, a portion of pixel 24, pixel 22, and pixel 23. In this case, the position of pixel 11 relative to the lens 320 positioned on the first horizontal line H1 and the position of pixel 21 relative to the lens 320 positioned on the second horizontal line H2 can be considered as being arranged by shifting a first distance PSV in the horizontal direction (D1 direction).

[0148] Since the lens 320 covering the pixel P included in the same c-th unit Uc is arranged in a manner specifically shifted along the horizontal line, the stereoscopic image display device according to an exemplary embodiment of the present disclosure can prevent vertical image distortion.

[0149] Furthermore, since the lens 320 covering pixel P is shifted, the arrangement of shifted pixels P is unnecessary, thus minimizing or eliminating additional changes in the arrangement of pixel P and the black matrix 124. This minimizes the brightness deviation of each pixel P and minimizes the brightness reduction of pixel P. Additionally, since it is not necessary to arrange the lens 320 in an angle relative to the arrangement direction of pixel P, image degradation caused by the lens 320 can be suppressed or prevented. Furthermore, a high-resolution stereoscopic image display device can be realized in which the brightness deviation and brightness reduction of pixel P are minimized, thereby reducing the power consumption of the display device.

[0150] Figure 8 This is a view used to describe a first rule of a color array according to an exemplary embodiment of this disclosure. Figure 9 It is a diagram used to describe a second rule for a color array according to an exemplary embodiment of the present disclosure. Figure 10 This is a diagram used to describe a third rule of a color array according to an exemplary embodiment of this disclosure.

[0151] Reference Figures 8 to 10A display device according to an exemplary embodiment of the present disclosure may include a first pixel implementing a first color C1, a second pixel implementing a second color C2, and a third pixel implementing a third color C3. The first pixel to the third pixel may each be configured as a plurality of pixels. The first color C1, the second color C2, and the third color C3 may be selected from a group consisting of red, green, and blue in a non-overlapping manner. For example, the first color C1 may be red, the second color C2 may be green, and the third color C3 may be blue. In an exemplary embodiment, for example, the set of pixels including the first pixel, the second pixel, and the third pixel may be referred to as a unit pixel.

[0152] In one exemplary embodiment, the first color C1, the second color C2, and the third color C3 can be different colors. That is, the first color C1 and the second color C2 can be different colors, the first color C1 and the third color C3 can be different colors, and the second color C2 and the third color C3 can be different colors. In one exemplary embodiment, the colors implemented by the first pixel, the second pixel, and the third pixel can be different.

[0153] Multiple first to third pixels can form a cell with an M×N array, wherein N pixels are disposed on a first direction D1 and M pixels are disposed on a second direction D2 intersecting the first direction D1. In this disclosure, the term "cell" refers only to the collection of the number of pixels disposed thereon. Unless it is specified that particular pixels are arranged sequentially or repeatedly, the term "cell" refers only to the number of pixels included or arranged according to the cell, and is not intended to limit any particular arrangement order.

[0154] The unit may include a first unit U1a, a second unit U1b, a third unit U1c, and a fourth unit U1.

[0155] For example, multiple first to third pixels can form a first unit U1a with a 1×3 array of first, second, and third pixels arranged in a first direction D1. In the first unit U1a, the first, second, and third pixels can be positioned in the first direction D1 and aligned along the third direction D3.

[0156] The first unit U1a may include the eleventh unit U1a1, the twelfth unit U1a2, and the thirteenth unit U1a3. The eleventh unit U1a1 may include a first pixel, a second pixel, and a third pixel arranged sequentially along the first direction D1. The twelfth unit U1a2 may include a third pixel, a first pixel, and a second pixel arranged sequentially along the first direction D1. The thirteenth unit U1a3 may include a second pixel, a third pixel, and a first pixel arranged sequentially along the first direction D1.

[0157] For example, multiple first to third pixels can form a second unit U1b with a 3×3 array having an 11th unit U1a1, a 12th unit U1a2, and a 13th unit U1a3 disposed in the second direction D2. In the second unit U1b, the 11th unit U1a1, the 12th unit U1a2, and the 13th unit U1a3 can be disposed by alignment in the first direction D1 and the third direction D3.

[0158] The second unit U1b may include the 21st unit U1b1, the 22nd unit U1b2, and the 23rd unit U1b3. The 21st unit U1b1 may include the 11th unit U1a1, the 12th unit U1a2, and the 13th unit U1a3, which are sequentially arranged on the third-party direction D3. The 22nd unit U1b2 may include the 13th unit U1a3, the 11th unit U1a1, and the 12th unit U1a2, which are sequentially arranged on the third-party direction D3. The 23rd unit U1b3 may include the 12th unit U1a2, the 13th unit U1a3, and the 11th unit U1a1, which are sequentially arranged on the third-party direction D3.

[0159] The colors achieved by the pixels set along the third direction D3 in the second unit U1b can be different. For example, the second unit U1b may include a first pixel, a third pixel, and a second pixel set along the third direction D3. The second unit U1b may include a second pixel, a first pixel, and a third pixel set along the second direction D2. The 32nd unit U1bc may include a third pixel, a second pixel, and a first pixel set along the second direction D2.

[0160] For example, multiple first to third pixels can form a third unit U1c with a 3×9 array having a 21st unit U1b1, a 22nd unit U1b2, and a 23rd unit U1b3 disposed in a first direction D1. In the third unit U1c, the 21st unit U1b1, the 22nd unit U1b2, and the 23rd unit U1b3 can be disposed by alignment in the first direction D1 and the third direction D3.

[0161] The third unit U1c may include the 31st unit U1c1, the 32nd unit U1c2, and the 33rd unit U1c3. The 31st unit U1c1 may include the 21st unit U1b1, the 22nd unit U1b2, and the 23rd unit U1b3 arranged sequentially in the first direction D1. The 32nd unit U1c2 may include the 23rd unit U1b3, the 21st unit U1b1, and the 22nd unit U1b2 arranged sequentially in the first direction D1. The 33rd unit U1c3 may include the 22nd unit U1b2, the 23rd unit U1b3, and the 21st unit U1b1 arranged sequentially in the first direction D1.

[0162] For example, multiple first to third pixels can form a fourth unit U1, consisting of units 31 U1c1, 32 U1c2, and 33 U1c3, positioned on a third direction D3. In the fourth unit U1, units 31 U1c1, 32 U1c2, and 33 U1c3 can be aligned on a first direction D1 and a third direction D3.

[0163] Figure 11 This is a schematic plan view illustrating a display device with a color array according to an exemplary embodiment of the present disclosure. Figure 12 This is a schematic plan view illustrating a display device with a color array according to an exemplary embodiment of the present disclosure. Figure 13 It is a graph used to describe the reduction of color moire phenomenon in display devices.

[0164] Further reference Figures 11 to 13 The fourth unit U1 may include the 31st unit U1c1, the 32nd unit U1c2 and the 33rd unit U1c3 arranged sequentially along the third direction D3.

[0165] In one exemplary embodiment, the display device may include a plurality of lenses 320. The plurality of lenses 320 may be repeatedly arranged along the D1 direction and may be repeatedly arranged along the D3 direction. The plurality of lenses 320 may be individually arranged in each horizontal line H1, H2, H3, H4, etc. Alternatively, the plurality of lenses 320 may also be repeatedly arranged along the D1 direction in each horizontal line H1, H2, H3, H4, etc.

[0166] Multiple lenses 320 arranged repeatedly along the D1 direction can be aligned. Adjacent lenses 320 in the D3 direction can be shifted in the D1 direction.

[0167] The spacing width (width in the D1 direction) of each of the plurality of lenses 320 may correspond to, but is not limited to, the width of three pixels (e.g., a first pixel, a second pixel, and a third pixel) arranged along the first direction D1. For example, the spacing width may correspond to the width of six pixels (e.g., a first pixel, a second pixel, a third pixel, a second pixel, a third pixel, and a first pixel) arranged along the first direction D1. As described above, the width of a pixel may include both the width of the opening region and the width of the black matrix and / or the embankment arranged to surround the opening region in the region adjacent to the opening region, but is not limited to.

[0168] The lens 320 can be positioned along the direction in which light is emitted from the pixel (e.g., the Z-axis direction) and can have a convex shape in the direction in which light is emitted from the pixel (e.g., the Z-axis direction).

[0169] In one exemplary embodiment, the display device may have a fourth unit U1 repeatedly arranged along a first direction D1. The display device may have a fourth unit U1 repeatedly arranged along a third direction D3.

[0170] In the color arrangement of a display device, such as that described in an exemplary embodiment of this disclosure, the color arrangement viewed from the left viewing angle (LVA) may differ from the color arrangement viewed from the right viewing angle (RVA). For example, the color arrangement viewed from the left viewing angle (LVA) may be a first color, a third color, and a second color along a third direction (D3), while the color arrangement viewed from the right viewing angle (RVA) may be a third color, a second color, and a first color along a third direction (D3). In one exemplary embodiment, due to the uniform mixing of colors C1, C2, and C3 in the first direction (D1), the second direction (D2), and the third direction (D3), the arrangement of colors C1, C2, and C3 viewed from the left viewing angle (LVA) can be shown continuously without difference. Furthermore, due to the uniform mixing of colors C1, C2, and C3 in the first direction (D1), the second direction (D2), and the third direction (D3), the arrangement of colors C1, C2, and C3 viewed from the right viewing angle (RVA) can be shown continuously without difference. This reduces color moiré effects in the display device.

[0171] Other exemplary embodiments of this disclosure will be described below. Among the components included in these other exemplary embodiments, those referenced are... Figures 1 to 13 The descriptions are essentially the same, the same reference numerals are used, and overlapping content is omitted or only briefly described.

[0172] Figure 14 This is a view used to describe a fourth rule of a color array according to another exemplary embodiment of this disclosure. Figure 15 This is a view used to describe the fifth rule of a color array according to another exemplary embodiment of this disclosure. Figure 16 This is a view used to describe a sixth rule of a color array according to another exemplary embodiment of this disclosure.

[0173] Reference Figures 14 to 16 The stereoscopic image display device 10_1 according to this exemplary embodiment includes a plurality of pixels P, and the colors C1, C2, and C3 of the plurality of pixels P can be correlated with the color of the pixels P. Figures 8 to 10 Different patterns can be arranged.

[0174] Specifically, according to this exemplary embodiment, a plurality of first to third pixels can form a unit with an M×N array, wherein N pixels are disposed on a first direction D1 and M pixels are disposed on a third direction D3 intersecting the first direction D1.

[0175] The unit may include the first unit U2a, the second unit U2b, the third unit U2c, the fifth unit U2e, and the sixth unit U2.

[0176] For example, multiple first to third pixels can form a first unit U2a having a 1×3 array in which the first, second and third pixels are arranged along a first direction D1.

[0177] The first unit U2a may include the 14th unit U2a4, the 15th unit U2a5, and the 16th unit U2a6. The 14th unit U2a4 may include a first pixel, a second pixel, and a third pixel arranged sequentially along the first direction D1. The 15th unit U2a5 may include a second pixel, a third pixel, and a first pixel arranged sequentially along the first direction D1. The 16th unit U2a6 may include a third pixel, a first pixel, and a second pixel arranged sequentially along the first direction D1.

[0178] For example, multiple first to third pixels can form a second unit U2b having a 3×3 array in which the 11th, 12th and 13th units are arranged along the third direction D3.

[0179] The second unit U2b may include the 24th unit U2b4, the 25th unit U2b5, and the 26th unit U2b6. The 24th unit U2b4 may include the 14th unit U2a4, the 15th unit U2a5, and the 16th unit U2a6 arranged sequentially along the third direction D3.

[0200] For example, multiple first to third pixels can form a sixth unit U2, wherein the 34th unit U2c4, the 35th unit U2c5, the 36th unit U2c6, the 37th unit U2c7, the 38th unit U2c8, the 39th unit U2c9, the 310th unit U2c10, the 311th unit U2c11, and the 312th unit U2c12 are set along the third direction D3.

[0202] Even in this case, multiple lenses 320 can be set on each pixel P (see reference). Figure 7 Multiple lenses 320 (see) Figure 7 ) can be set to be Figure 7 The layouts are basically the same.

[0203] Therefore, variations in the arrangement of the additional pixels P and in the black matrix 124 can be minimized or eliminated. This minimizes the brightness deviation of each pixel P and the brightness reduction of pixel P. Furthermore, a high-resolution stereoscopic image display device can be implemented in which the brightness deviation and brightness reduction of pixel P are minimized, thereby reducing the power consumption of the display device.

[0204] Figure 17 This is a cross-sectional view of a stereoscopic image display device according to another exemplary embodiment.

[0205] Figure 17 The cross-sectional structure of the stereoscopic image display device 10_2 is shown schematically.

[0206] Reference Figure 17 The stereoscopic image display device 10_2 according to this exemplary embodiment may also include a passivation film 330.

[0207] The viewing angle control device 300 may include a base film 310, a plurality of lenses 320 disposed on the base film 310, and a passivation film 330.

[0208] The passivation film 330 may be formed of a transparent insulating material. For example, the passivation film 330 may include at least one selected from transparent silicon (Si), silicon compounds, silicon oxide, etc.

[0209] Multiple lenses 320 can be disposed on different layers. For example, some of the multiple lenses 320 can be disposed on the passivation film 330, and the remaining lenses can be disposed on the base film 310.

[0210] Some of the multiple lenses 320 can be disposed on one surface of the passivation film 330, and the remaining lenses can be disposed on another surface of the passivation film 330. Here, one surface and another surface of the passivation film 330 can refer to opposite surfaces.

[0211] For example, some of the multiple lenses 320 can be disposed on one surface of the passivation film 330, and the rest can be disposed on another surface of the passivation film 330. Furthermore, the lenses 320 disposed on one surface of the passivation film 330 and the lenses 320 disposed on the other surface of the passivation film 330 can be arranged alternately and repeatedly in the X-axis direction.

[0212] Exemplary embodiments of this disclosure are not limited thereto, but some of the plurality of lenses 320 may directly contact one surface of the passivation film 330, and the remaining ones may directly contact the other surface of the passivation film 330.

[0213] Furthermore, although not illustrated, lenses 320 disposed on one surface of the passivation film 330 and lenses 320 disposed on the other surface of the passivation film 330 can be repeatedly and alternately disposed in the Y-axis direction. However, the exemplary embodiments of this disclosure are not limited thereto, and lenses 320 repeatedly disposed in the Y-axis direction can be disposed on the same surface of the passivation film 330.

[0214] The passivation film 330 improves the formability of multiple lenses 320, thus enabling the formation of multiple lenses 320 more smoothly.

[0215] Even in this case, the additional pixel P (see Figure 7 Variations in the arrangement of pixels and in the black matrix 124 can also be minimized or eliminated. This allows for the minimization of the brightness deviation of each pixel P (see [reference]). Figure 7), and can minimize the reduction in brightness of pixel P (see reference). Figure 7 Furthermore, a high-resolution stereoscopic image display device can be realized in which the brightness deviation and brightness reduction of pixel P can be minimized, thereby reducing the power consumption of the display device.

[0216] Figure 18 This is a cross-sectional view of a stereoscopic image display device according to another exemplary embodiment.

[0217] Figure 18 The cross-sectional structure of the stereoscopic image display device 10_3 is schematically shown.

[0218] Reference Figure 18 The stereoscopic image display device 10_3 may include a viewing angle control device 300, and the viewing angle control device 300 may include a polarizing plate POL, a phase delay plate QWP disposed on the polarizing plate POL, and a liquid crystal optical element GP disposed on the phase delay plate QWP.

[0219] In other words, in this exemplary embodiment, the optical path control component can also be formed as a liquid crystal optical element (GP).

[0220] A polarizing plate (POL) can be a linear polarizing plate that polarizes incident light in one direction and transmits it. A polarizing plate (POL) can also be made by adsorbing dichroic substances such as iodine or dichroic dyes onto a hydrophilic polymer film such as a polyvinyl alcohol-based film, a partially shaped polyvinyl alcohol-based film, or a partially saponified ethylene-vinyl acetate copolymer film, and then uniaxially stretching the hydrophilic substance; or it can be a polarizing plate made from polyolefin-oriented films such as dehydrated polyvinyl alcohol products or dehydrochlorinated polyvinyl chloride products.

[0221] The phase delay plate (QWP) can be a quarter-wave plate or a half-wave plate. The phase delay plate can be formed by stretching a cyclic olefin polymer (COP) film.

[0222] The phase delay plate QWP can be placed between the polarizer POL and the liquid crystal optical element GP.

[0223] The liquid crystal optical element GP may include a first transparent electrode TE1 and a second transparent electrode TE2 opposite to each other, and a liquid crystal layer CL disposed between the first transparent electrode TE1 and the second transparent electrode TE2. The first transparent electrode TE1 may be disposed between the phase retardation plate QWP and the liquid crystal layer CL.

[0224] The first transparent electrode TE1 and the second transparent electrode TE2 may each include a TCO, such as ITO, IZO, IGZO, ATO, etc., but are not limited to these. The alignment of liquid crystal molecules in the liquid crystal layer CL can be controlled by the electric field generated when an electrical signal is applied to the first transparent electrode TE1 and the second transparent electrode TE2.

[0225] The liquid crystal layer CL can have any liquid crystal structure that can polarize light linearly polarized by the polarizer POL. For example, the liquid crystal layer CL can have one of the following driving modes: vertical alignment (VA) mode, patterned vertical alignment (PVA) mode, in-plane switching (IPS) mode, advanced horizontal in-plane switching (AH-IPS) mode, plane-to-line switching (PLS) mode, electrically controlled birefringence (ECB) mode, twisted nematic (TN) mode, super-twisted nematic (STN) mode, and a hybrid mode.

[0226] Liquid crystal molecules exhibit polarization characteristics and optical anisotropy. Here, polarization characteristics refer to the fact that when liquid crystal molecules are placed in an electric field, the alignment direction of the molecules changes according to the electric field by concentrating the charges in the liquid crystal molecules on both sides of the liquid crystal molecules. Optical anisotropy refers to the fact that due to the elongated structure of the liquid crystal molecules and the aforementioned molecular alignment direction, the path or polarization state of the outgoing light changes differently depending on the incident direction or the polarization state of the incident light.

[0227] When the liquid crystal layer CL is driven by generating an electric field by applying different voltages to the positions of each of the first transparent electrode TE1 and the second transparent electrode TE2, the incident light incident on the liquid crystal layer CL has a position-specific phase change, so the liquid crystal layer CL can control the path of the incident light like an actual lens.

[0228] The liquid crystal optical element GP is configured as multiple liquid crystal optical elements. These multiple liquid crystal optical elements GP can be coupled with... Figure 7 It is set up in basically the same way as lens 320 and can perform the same function as lens 320.

[0229] Even in this case, the additional pixel P (see Figure 7 Variations in the arrangement of pixels and in the black matrix 124 can be minimized or eliminated. This allows for the minimization of the brightness deviation of each pixel P (see [reference]). Figure 7 ), and can minimize the reduction in brightness of pixel P (see reference). Figure 7 Furthermore, a high-resolution stereoscopic image display device can be realized in which the brightness deviation and brightness reduction of pixel P can be minimized, thereby reducing the power consumption of the display device.

[0231] Figure 19 The cross-sectional structure of the stereoscopic image display device 10_4 is shown schematically.

[0232] Reference Figure 19The stereoscopic image display device 10_4 may include a viewing angle control device 300, and the viewing angle control device 300 may include a substrate BS defining a groove GR and a filler RS ​​filling the groove GR.

[0233] In other words, the optical path control component in this exemplary embodiment can also be formed from a substrate BS and a filler RS.

[0234] The substrate BS can be a transparent substrate. The substrate BS can be formed from, for example, transparent glass, but is not limited thereto. The substrate BS can define multiple grooves GR in the Z-axis direction.

[0235] The groove GR can be etched into a concave shape in the direction of light emission. The groove GR can have rounded corners in the cross-sectional view, but is not limited to this. Multiple grooves GR can be arranged in a manner consistent with... Figure 7 The lens 320 is set up in basically the same way.

[0236] Filler RS ​​can fill the groove GR. Filler RS ​​can be formed of a resin with a refractive index higher than that of the substrate BS, but is not limited to this. Each of the filler RS ​​filling the groove GR can be... Figure 7 It is set up in basically the same way as lens 320 and can perform the same function as lens 320.

[0237] The viewing angle control device 300 may also include, but is not limited to, a membrane covering the exposed filler RS.

[0238] Even in this case, the additional pixel P (see Figure 7 Changes in the arrangement of pixels and the black matrix 124 can also be minimized or eliminated. This allows for the minimization of the brightness deviation of each pixel P (see [reference]). Figure 7 ), and can minimize the reduction in brightness of pixel P (see reference).
