[0003] Among display devices, a head mounted display (HMD) is a device mounted on a user's head to display images to the user. The head mounted display has recently attracted attention as a visualization device that provides virtual reality (VR) or augmented reality (AR).

[0004] The HMD includes a display panel for displaying an image and an optical component disposed between the display panel and a user. The optical component magnifies the image displayed on the display panel so that the user can view the image.

[0005] When an image of a display panel is magnified by optical components, a screen door effect (SDE) occurs in which the image is viewed as if through a mesh or a non-display area appears black, which results in degradation of display quality and readability of text.

[0006] The above information disclosed in this Background section is only for enhancement of understanding of the background of the invention and therefore it may contain information that does not form the prior art that is already known in this country to a person of ordinary skill in the art.

[0042] In the following description, for the purpose of explanation, many specific details are set forth in order to provide a thorough understanding of various exemplary embodiments of the invention. As used herein, an "embodiment" is a non-restrictive example of a device or method using one or more inventive concepts disclosed herein. However, it is apparent that various exemplary embodiments can be implemented without these specific details or with one or more equivalent arrangements. In other examples, known structures and devices are shown in block diagram form to avoid unnecessary obscurity of various exemplary embodiments. In addition, various exemplary embodiments may be different, but need not be exclusive. For example, without departing from the inventive concept, the specific shape, construction and characteristics of an exemplary embodiment may be used or implemented in another exemplary embodiment.

[0043] Unless otherwise specified, the exemplary embodiments shown will be understood as providing exemplary features of varying details of some ways in which the inventive concept can be implemented in practice. Therefore, without departing from the inventive concept, unless otherwise specified, the features, components, modules, layers, films, panels, regions and / or aspects of the various embodiments, etc. (hereinafter individually or collectively referred to as "elements") may be further combined, separated, exchanged and / or rearranged.

[0044] The use of cross hatching and / or shadows is usually provided in the drawings to make the boundaries between adjacent elements clear. In this way, unless otherwise specified, the presence or absence of cross hatching or shadows does not convey or indicate any preference or requirement for the specific material, material properties, size, ratio, commonality between the elements shown in the elements, and / or any other characteristics, attributes, properties, etc. of the elements. In addition, in the drawings, the size and relative size of the elements can be exaggerated for clarity and / or descriptive purposes. When the exemplary embodiments can be implemented differently, the specific process sequence can be performed differently from the described sequence. For example, two processes described in succession can be performed substantially simultaneously, or two processes described in succession can be performed in an order opposite to the described order. In addition, the same reference numerals represent the same elements.

[0045] When an element such as a layer is referred to as being "on" another element or layer, "connected to" or "bonded to" another element or layer, the element or layer may be directly on, directly connected to or directly bonded to the other element or layer, or there may be an intermediate element or layer. However, when an element or layer is referred to as being "directly on" another element or layer, "directly connected to" or "directly bonded to" another element or layer, there is no intermediate element or layer. For this reason, the term "connection" may refer to a physical connection, an electrical connection, and / or a fluid connection with or without an intermediate element. In addition, the D1 axis, the D2 axis, and the D3 axis are not limited to the three axes of a rectangular coordinate system (such as an x-axis, a y-axis, and a z-axis), but may be interpreted in a broader sense. For example, the D1 axis, the D2 axis, and the D3 axis may be perpendicular to each other, or may represent different directions that are not perpendicular to each other. For the purpose of this disclosure, "at least one of X, Y, and Z" and "at least one selected from the group consisting of X, Y, and Z" may be interpreted as only X, only Y, only Z, or any combination of two or more of X, Y, and Z, such as XYZ, XYY, YZ, and ZZ for example. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0046] Although the terms "first", "second", etc. may be used herein to describe various types of elements, these elements should not be limited by these terms. These terms are used to distinguish one element from another element. Therefore, without departing from the disclosed teachings, the first element discussed below may be referred to as the second element.

[0047] For descriptive purposes, spatially relative terms such as "under," "below," "below," "above," "above," "higher," and "side" (e.g., as in "sidewall") may be used herein to describe the relationship of one element to other elements as shown in the figures. In addition to the orientations depicted in the figures, spatially relative terms are intended to include different orientations of the device in use, operation, and / or manufacture. For example, if the device in the accompanying drawings is turned over, an element described as "under" or "under" other elements or features will subsequently be positioned as "above" the other elements or features. Thus, the exemplary term "under" can include both above and below orientations. In addition, the device can be positioned otherwise (e.g., rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0048] The terms used herein are only for the purpose of describing specific embodiments, and are not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms "one", "a kind of" and "the (said)" are also intended to include plural forms. In addition, when the terms "include", "comprise" and / or its various variations are used in this specification, it is explained that there are stated features, integral bodies, steps, operations, elements, components and / or their groups, but it is not excluded that there are or add one or more other features, integral bodies, steps, operations, elements, components and / or their groups. It is also noted that, as used herein, the terms "substantially", "approximately" and other similar terms are used as approximate terms rather than degree terms, and as such, are used to explain the inherent deviations of the measured values, calculated values ​​and / or provided values ​​that will be recognized by those of ordinary skill in the art.

[0049] Various exemplary embodiments are described herein with reference to cross-sectional views and / or exploded views that are schematic diagrams of idealized exemplary embodiments and / or intermediate structures. As such, variations in the shapes of the illustrations, such as those caused by manufacturing techniques and / or tolerances, are contemplated. Therefore, the exemplary embodiments disclosed herein should not necessarily be construed as being limited to the shapes of the specifically illustrated regions, but rather will include deviations in shape caused by, for example, manufacturing. In this manner, the regions illustrated in the accompanying drawings may be schematic in nature, and the shapes of these regions may not reflect the actual shapes of the regions of the device, and as such, no limitation is necessarily intended.

[0050] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those of ordinary skill in the art to which this disclosure is a part. Unless expressly defined as such herein, terms (such as those defined in general dictionaries) should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and should not be interpreted in an ideal or overly formal sense.

[0051] In the following, reference will be made to Figure 1A and Figure 1B A display device according to an exemplary embodiment is described. Figure 1A and Figure 1B A schematic diagram of a display device according to an exemplary embodiment is shown. For better understanding and ease of description, a state in which the display device is installed on a user is shown.

[0052] like Figure 1A As shown in , the display device 1 according to the exemplary embodiment is mounted on the head of the user U, and displays images to the eyes (left eye and right eye) of the user U. Figure 1BThe display device 1 includes a display panel 10, an optical component 20 overlapped with the display panel 10, and a housing 30 on which the display panel 10 and the optical component 20 are mounted.

[0053] The display panel 10 is mounted on the housing 30 and displays an image. The display panel 10 may include a plurality of display panels corresponding to the left eye and the right eye of the user U. In the present specification, the display panel 10 corresponding to each of the left eye and the right eye is shown as being separated, but the inventive concept is not limited thereto, and the display panels corresponding to the left eye and the right eye may be connected to each other to form an integrated whole.

[0054] The display panel 10 may be a light emitting diode display panel, but the inventive concept is not limited thereto, and the display panel 10 may be a liquid crystal display panel.

[0055] The optical component 20 overlaps the display panel 10 and is disposed between the user U and the display panel 10. The optical component 20 refracts an image displayed on the display panel 10 in the direction of the eyes of the user U. The display device 1 may include a plurality of optical components 20 corresponding to left and right eyes, respectively.

[0056] For example, the optical member 20 may include a convex lens convex toward the display panel 10. The optical member 20 may include a concave lens for correcting distortion caused by the convex lens. In this case, the concave lens may be an aspherical lens, but the inventive concept is not limited thereto.

[0057] The housing 30 may be made into any shape as long as it can be mounted on the head of the user U with the display panel 10 and the optical member 20 mounted therein. The housing 30 may have various shapes, for example, a glasses shape or a helmet shape.

[0058] In the following, reference will be made to Figures 2 to 4B A structure of a display panel according to an exemplary embodiment is described. Figure 2 shows a schematic cross-sectional view of a display panel according to an exemplary embodiment, Figure 3 shows a schematic plan view of a display panel according to an exemplary embodiment, Figure 4A A schematic diagram showing a pattern shape viewed by a user in a state in which an inorganic layer is removed from a display panel, Figure 4B A schematic diagram showing a pattern shape viewed by a user in a state in which an inorganic layer is included.

[0059] Reference Figure 2 and Figure 3, the display panel 10 according to the exemplary embodiment includes a display part 120 disposed on a first substrate 111 and including a plurality of pixels, a second substrate 112 covering the display part 120 , a sealing part 130 combining the first substrate 111 and the second substrate 112 , and an inorganic layer 140 disposed on the second substrate 112 .

[0060] The first substrate 111 according to this exemplary embodiment includes a display area DA overlapping a plurality of pixels and a peripheral area PA surrounding the display area DA. The peripheral area PA may overlap an edge of the first substrate 111 and may be disposed outside the display area DA.

[0061] The first substrate 111 may be an insulating substrate including glass, quartz, ceramic, plastic, etc., or a metal substrate including stainless steel, etc. In some exemplary embodiments, the first substrate 111 may be flat or flexible.

[0062] The display unit 120 may include a plurality of pixels. One pixel may include a thin film transistor and a light emitting diode connected to the thin film transistor. Fig.14 A thin film transistor and a light emitting diode connected to the thin film transistor are described. The display part 120 is not limited to including the thin film transistor and the light emitting diode, but may include the thin film transistor and a liquid crystal layer.

[0063] The second substrate 112 may be a packaging substrate disposed on the display part 120. The second substrate 112 may be an insulating substrate including glass, quartz, ceramic or plastic, or a metal substrate including stainless steel, etc. The second substrate 112 may be a flexible or bendable transparent resin substrate or a flat substrate.

[0064] The inorganic layer 140 may be disposed on the second substrate 112. The inorganic layer 140 may be disposed outside the second substrate 112. The inorganic layer 140 may be disposed on one surface of the second substrate 112, and the other surface of the second substrate 112 faces the display part 120. The display part 120, the second substrate 112, and the inorganic layer 140 may be sequentially stacked along a direction D3 relative to the first substrate 111.

[0065] The inorganic layer 140 may overlap the first substrate 111 and the second substrate 112. Specifically, the inorganic layer 140 may overlap the display area DA and the peripheral area PA.

[0066] The inorganic layer 140 may include any inorganic material, and may include, for example, silicon nitride, silicon oxide, and the like.

[0067] The inorganic layer 140 may include a plurality of openings OP. The openings OP may completely penetrate the inorganic layer 140. The openings OP may refer to regions in which the inorganic layer 140 is removed along a thickness direction of the inorganic layer 140 (which corresponds to a direction D3).

[0068] The plurality of openings OP included in the inorganic layer 140 may overlap not only the display area DA but also the peripheral area PA. The area of ​​a plane occupied by the plurality of openings OP may be about 60% to about 70% of the sum of the areas of the display area DA and the peripheral area PA. In this specification, a plane refers to a plane formed along the direction D1 and the direction D2.

[0069] The planar shape of the opening OP may be, for example, a circle. However, the planar shape of the opening OP is not limited thereto, and the opening OP may have various shapes such as a triangle, a rectangle, a polygon, and an ellipse.

[0070] The opening OP may include a first opening OP1 overlapping the display area DA and a second opening OP2 overlapping the peripheral area PA. Although not shown, at least one of the first opening OP1 and the second opening OP2 may be disposed at a boundary between the display area DA and the peripheral area PA. The first opening OP1 disposed at the boundary between the display area DA and the peripheral area PA may overlap both the display area DA and the peripheral area PA. The second opening OP2 disposed at the boundary between the display area DA and the peripheral area PA may overlap both the display area DA and the peripheral area PA.

[0071] In this specification, the distance between the respective centers of two adjacent openings OP is referred to as a "pitch". Figure 3 , a distance between corresponding centers C1 of two adjacent first openings OP1 disposed in the display area DA is a first pitch P1. A distance between corresponding centers C2 of two adjacent second openings OP2 disposed in the peripheral area PA is a second pitch P2.

[0072] According to an exemplary embodiment, the first pitch P1 and the second pitch P2 may be substantially the same. The distance between the centers C1 of the plurality of first openings OP1 overlapping the display area DA may be substantially the same as the distance between the centers C2 of the plurality of second openings OP2 overlapping the peripheral area PA. The spacing between the plurality of openings OP1 and the spacing between the plurality of openings OP2 may be substantially the same in both the display area DA and the peripheral area PA. The spacing or distance between the plurality of openings OP1 and the spacing or distance between the plurality of openings OP2 may refer to the minimum linear distance between the centers C1 of adjacent openings OP1 and the minimum linear distance between the centers C2 of adjacent openings OP2. Similarly, the spacing or distance between the centers C1 of the plurality of openings OP1 and the spacing or distance between the centers C2 of the plurality of openings OP2 may refer to the minimum linear distance between the centers C1 of adjacent openings OP1 and the minimum linear distance between the centers C2 of adjacent openings OP2, respectively.

[0073] Each of the first and second pitches P1 and P2 may be about 5 μm to about 10 μm. When each of the first and second pitches P1 and P2 is less than about 5 μm or greater than about 10 μm, light passing through the inorganic layer 140 may not be effectively diffracted or scattered.

[0074] The diameter h1 of the first opening OP1 and the diameter h2 of the second opening OP2 may be substantially the same. Figure 3 As shown in FIG, the planar sizes of the first opening OP1 overlapping the display area DA and the second opening OP2 overlapping the peripheral area PA may be substantially the same. The plurality of openings OP1 and OP2 overlapping the display area DA and the peripheral area PA may have substantially the same size.

[0075] The diameter h1 of the first opening OP1 may be from about 55% to about 85% of the first pitch P1, for example, from about 65% to about 75% of the first pitch P1. The diameter h2 of the second opening OP2 may be from about 55% to about 85% of the second pitch P2, for example, from about 65% to about 75% of the second pitch P2. The first opening OP1 and the second opening OP2 may have substantially the same diameter within the above range. When the diameters of the first opening OP1 and the second opening OP2 are less than 55% of the pitch or greater than 85% of the pitch, the light emitted from the display part 120 cannot be effectively diffracted or scattered.

[0076] When the inorganic layer 140 is disposed on the second substrate 112, as in the present exemplary embodiment, the light L0 emitted from the display part 120 may be diffracted, scattered, or refracted. This will refer to Figure 2 , Figure 4A and Figure 4B Give a description.

[0077] Figure 4A 1 shows a case where no separate inorganic layer is provided on the second substrate 112. Figure 4A As shown in FIG. 1 , one pixel included in the display part 120 may be viewed by a user as one pixel PX1 by emitting light.

[0078] However, in the case of including the inorganic layer 140 disposed on the second substrate 112, the light L0 emitted from the display part 120 may be transmitted to the user as it is, and may be as shown by Figure 2 According to the diffraction, scattering or refraction of the light emitted from the display component 120, as shown by the dotted line in FIG. Figure 4B As shown in , the user can view multiple virtual pixels PX1' based on one pixel PX1. The multiple virtual pixels PX1' can have the same effect as that of one pixel PX1. Thus, an image with a higher resolution than the actual resolution of the display part 120 can be provided.

[0079] Since the display device according to this exemplary embodiment includes the optical member 20, the image provided from the display member 120 can be magnified and viewed by the user. In this case, a screen door effect (SDE) in which a mesh shape is viewed or a non-pixel region between pixel regions is viewed as black may occur. According to this exemplary embodiment, when a plurality of virtual pixels PX1' is viewed as one pixel PX1 that is copied, the screen door effect in which a non-pixel region or the like is viewed can be reduced.

[0080] The inorganic layer 140 according to this exemplary embodiment may include a large number of openings OP to achieve the effect in which the pixels are replicated as described above. The inorganic layer 140 may be manufactured by a manufacturing process in which inorganic materials are stacked and openings are formed. In this case, a load is generated in the process of forming a large number of openings OP. When the process of forming the openings OP is repeated multiple times, a plurality of openings OP are formed unevenly, resulting in uneven sizes or spacings of the openings OP overlapped with the display area DA. When a plurality of openings OP having uneven shapes or uneven arrangements are included, the transmittance of the display panel is reduced.

[0081] The inorganic layer 140 according to this exemplary embodiment may be provided with openings OP overlapping both the display area DA and the peripheral area PA. For this reason, when a process of forming openings in the entire surface of the substrate is performed, the uniformity of the formation of the openings may be improved compared to a process of forming openings in a portion of the substrate. A plurality of openings OP overlapping the display area DA and the peripheral area PA may be formed to have a uniform shape and a uniform interval.

[0082] In addition, due to the load in the manufacturing process, the shapes or spacings of some openings OP may be uneven. However, in this case, due to the load of the manufacturing process, the openings OP provided at the periphery of the plurality of openings OP may be formed in an uneven manner. The shape or spacing of the openings OP overlapping the peripheral area PA instead of the display area DA may be changed. The display quality of the image displayed in the display area DA is not greatly affected. The display panel according to this exemplary embodiment can improve the display quality.

[0083] In the following, reference will be made to Figures 5 to 12 Display panels according to other exemplary embodiments are described. Figures 5 to 12 A schematic plan view of a display panel according to an exemplary embodiment is shown. Hereinafter, only components different from those of the above-described exemplary embodiment will be described, and thus a detailed description of the same components will be omitted.

[0084] First, refer to Figure 5 , the inorganic layer 140 may overlap the display area DA and the peripheral area PA.

[0085] The inorganic layer 140 may include a plurality of openings OP. The plurality of openings OP included in the inorganic layer 140 may overlap not only the display area DA but also the peripheral area PA. The area of ​​a plane occupied by the plurality of openings OP may be about 60% to about 70% of the sum of the areas of the display area DA and the peripheral area PA.

[0086] The opening OP may include a first opening OP1 overlapping the display area DA and a second opening OP2 overlapping the peripheral area PA. Although not shown, at least one of the first opening OP1 and the second opening OP2 may be disposed at a boundary between the display area DA and the peripheral area PA.

[0087] A distance between respective centers C1 of two adjacent first openings OP1 disposed in the display area DA is a first pitch P1. A distance between respective centers C2 of two adjacent second openings OP2 disposed in the peripheral area PA is a second pitch P2.

[0088] According to an exemplary embodiment, the first pitch P1 and the second pitch P2 may be substantially the same. The straight-line distance between the centers C1 of the plurality of first openings OP1 overlapping the display area DA may be substantially the same as the straight-line distance between the centers C2 of the plurality of second openings OP2 overlapping the peripheral area PA. The intervals between the centers of the plurality of openings OP1 and the intervals between the centers of the plurality of openings OP2 may be substantially the same in all of the display area DA and the peripheral area PA.

[0089] Each of the first and second pitches P1 and P2 may be about 5 μm to about 10 μm. When the first and second pitches P1 and P2 are less than about 5 μm or greater than about 10 μm, light passing through the inorganic layer 140 may not be effectively diffracted, scattered, or refracted.

[0090] The diameter h1 of the first opening OP1 may be greater than the diameter h2 of the second opening OP2. Figure 5 As shown in FIG, a planar size of the first opening OP1 overlapping the display area DA may be larger than a planar size of the second opening OP2 overlapping the peripheral area PA. A planar size of the second opening OP2 may be smaller than a planar size of the first opening OP1.

[0091] The diameter h1 of the first opening OP1 may be about 55% to about 85% of the first pitch P1. The diameter h2 of the second opening OP2 may be about 55% to about 85% of the second pitch P2.

[0092] According to this exemplary embodiment, i) each of the first opening OP1 and the second opening OP2 has a diameter corresponding to about 55% to about 85% of each of the first pitch P1 and the second pitch P2, and ii) a diameter h1 of the first opening OP1 may be greater than a diameter h2 of the second opening OP2.

[0093] Reference Figure 6 , the inorganic layer 140 may overlap the display area DA and the peripheral area PA.

[0094] The inorganic layer 140 may include a plurality of openings OP. The plurality of openings OP included in the inorganic layer 140 may overlap not only the display area DA but also the peripheral area PA. The area of ​​a plane occupied by the plurality of openings OP may be about 60% to about 70% of the sum of the areas of the display area DA and the peripheral area PA.

[0095] The opening OP may include a first opening OP1 overlapping the display area DA and a second opening OP2 overlapping the peripheral area PA. Although not shown, at least one of the first opening OP1 and the second opening OP2 may be disposed at a boundary between the display area DA and the peripheral area PA.

[0096] In this exemplary embodiment, a distance between respective centers C1 of two adjacent first openings OP1 disposed in the display area DA is a first pitch P1, and a distance between respective centers C2 of two adjacent second openings OP2 disposed in the peripheral area PA is a second pitch P2.

[0097] In some exemplary embodiments, the first pitch P1 and the second pitch P2 may be different. A distance between centers C1 of the first openings OP1 and a distance between centers C2 of the second openings OP2 may be different.

[0098] In some exemplary embodiments, the first pitch P1 may be smaller than the second pitch P2. A straight distance between centers C1 of the plurality of first openings OP1 overlapping the display area DA may be smaller than a straight distance between centers C2 of the plurality of second openings OP2 overlapping the peripheral area PA.

[0099] Each of the first pitch P1 and the second pitch P2 may be about 5 μm to about 10 μm. When the first pitch P1 and the second pitch P2 are less than about 5 μm or greater than about 10 μm, light passing through the inorganic layer 140 may not be effectively diffracted, scattered, or refracted. When the first pitch P1 and the second pitch P2 may satisfy the above numerical range, the second pitch P2 may be greater than the first pitch P1.

[0100] The diameter h1 of the first opening OP1 may be greater than the diameter h2 of the second opening OP2.
