[0044] Reference will now be made in detail to embodiments, examples of which are shown in the accompanying drawings, wherein the same reference numerals represent the same elements throughout. In this regard, embodiments may have different forms and should not be construed as being limited to the descriptions set forth herein. Therefore, embodiments are described below only by reference to the accompanying drawings to explain the aspects of the description. As used herein, the term "and / or" includes any and all combinations of one or more of the related listed items. Throughout the disclosure, the expression "at least one of a, b, and c" means only a, only b, only c, both a and b, both a and c, both b and c, all of a, b, and c, or variations thereof.

[0045] Note that as used herein, the terms "substantially," "about," and other similar terms are used as terms of approximation and not as terms of degree, and, thus, are used to account for the inherent deviations in measured, calculated, and / or provided values ​​that would be recognized by one of ordinary skill in the art.

[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 teachings of the present disclosure, the first element discussed below may be referred to as the second element.

[0047] It will be further understood that when used herein, the terms "comprising", "including", "includes", "having", "having" and the like specify the presence of stated features and / or elements, but do not exclude the presence or addition of other features and / or elements.

[0048] For descriptive purposes, spatially relative terms such as "below," "beneath," "under," "lower," "above," "upper," "above," "higher," "side" (e.g., as in "sidewall"), etc. may be used herein and thereby describe the relationship of one element to another element(s) as shown in the accompanying drawings. In addition to the orientations depicted in the accompanying drawings, spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture. For example, if the device in the accompanying drawings is flipped, elements described as being "below" or "below" other elements or features will then be oriented "above" the other elements or features. Thus, the exemplary term "below" may encompass both above and below orientations. Additionally, the device may be oriented in other ways (e.g., rotated 90 degrees or in other orientations), and therefore, the spatially relative descriptors used herein should be interpreted accordingly.

[0049] In the drawings, the size of the elements may be exaggerated or reduced for ease of description. For example, since the size and thickness of each element are arbitrarily shown in the drawings for ease of description, the present disclosure is not necessarily limited to those shown.

[0050] When some embodiments can be implemented differently, the specific process order can be performed differently from the described order. For example, two processes described in succession can be performed substantially simultaneously, or can be performed in the reverse order of the described order.

[0051] When an element (such as a layer) is referred to as being "on," "connected to," or "coupled to" another element, it may be directly on, directly connected to, or directly coupled to another element, or there may be intervening elements. However, when an element is referred to as being "directly" "on," "directly connected to," or "directly coupled to" another element, there are no intervening elements. For this purpose, the term "connected" may refer to a physical connection, an electrical connection, and / or a fluid connection with or without intervening elements. In addition, when an element is referred to as being "in contact with" or "contacting" another element, the element may be "electrically in contact with" or "in physical contact with" the other element; or "indirectly in contact with" or "directly in contact with" the other element.

[0052] The x-axis, y-axis, and z-axis are not limited to the three axes on the orthogonal coordinate system, and can be interpreted as a broad meaning including the three axes. For example, the x-axis, y-axis, and z-axis can be orthogonal to each other, but can also refer to different directions that are not orthogonal to each other.

[0053] Unless otherwise defined or implied herein, all terms (including technical and scientific terms) used have the same meaning as commonly understood by those skilled in the art to which the present disclosure belongs. It will also be understood that terms, such as those defined in commonly used 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 idealized or overly formal sense unless explicitly defined in the specification.

Each sub-pixel may include a reference Figure 3 The display area DA may include a sub-pixel area PA in which sub-pixels are arranged and a non-sub-pixel area NPA surrounding the sub-pixel area PA.

[0077] In the display area DA, subpixels may be two-dimensionally arranged in ±x and ±y directions. An array of subpixels (eg, an array of red subpixels PR, green subpixels PG, and blue subpixels PB) may be defined in the display area DA.

[0078] In an embodiment, the array of sub-pixels may include a plurality of columns (or pixel columns) arranged in the ±y direction. Among sub-pixels having different colors, two sub-pixels (e.g., red sub-pixels PR and blue sub-pixels PB) emitting light having different colors may be arranged in the same column, and another sub-pixel (e.g., green sub-pixels PG) may be arranged in another column.

According to an embodiment, the separator 20 may be arranged at the same intervals in the ±y direction, having a stripe shape in which the length in the ±x direction is greater than the length in the ±y direction. According to another embodiment, the separators 20 may each have a rectangular shape with rounded corners similar to the shape of the sub-pixel (i.e., the red sub-pixel PR, the green sub-pixel PG, and the blue sub-pixel PB), and may be arranged to surround each of the sub-pixels (e.g., the red sub-pixel PR, the green sub-pixel PG, and the blue sub-pixel PB).

[0083] FIG. 5A to FIG. 5C are schematic cross-sectional views each showing a state of a partition structure according to an embodiment of the present disclosure according to a manufacturing process thereof.

The display panel 10 may include the above reference Figure 2 The substrate 100 described (see Figure 2 ), display element layer 200 (see Figure 2 ), encapsulation layer 300 (see Figure 2 ) and / or input sensing layer 400.

[0085] The first separation layer 21' may include an inorganic material. For example, the first separation layer 21' may include molybdenum tantalum oxide (MTO). For example, the first separation layer 21' may include MTO having a tantalum (Ta) content in the range of 1 at% to 15 at%.

[0086] A photoresist PR may be formed on the first separation layer 21 ′. The photoresist PR may include an opening.

[0087] refer to Figure 5B , a plurality of first spacers 21 may be formed by etching the first spacer layer 21' using the photoresist PR as a mask. For example, the first spacers 21 may include a 1-1 spacer 21-a, a 1-2 spacer 21-b, and a 1-3 spacer 21-c. The 1-1 spacer 21-a, the 1-2 spacer 21-b, and the 1-3 spacer 21-c may be arranged at uniform intervals. At least one of the 1-1 spacer 21-a, the 1-2 spacer 21-b, and the 1-3 spacer 21-c may include an inorganic material, for example, molybdenum tantalum oxide (MoTaO x , MTO).

[0088] In a certain direction, the width W1 of each of the 1-1 separator 21-a, the 1-2 separator 21-b, and the 1-3 separator 21-c may be equal to or greater than 1.5 μm, and the structural stability of the 1-1 separator 21-a, the 1-2 separator 21-b, and the 1-3 separator 21-c may be ensured. For example, the width W1 of the 1-1 separator 21-a may be about 2.0 μm. Although Figure 5B It is shown that the widths W1 of the 1-1 spacer 21-a, the 1-2 spacer 21-b, and the 1-3 spacer 21-c are the same, but the present disclosure is not limited thereto. The widths W1 of the 1-1 spacer 21-a, the 1-2 spacer 21-b, and the 1-3 spacer 21-c may be different from each other. After forming the first spacer 21, the photoresist PR may be removed.

[0089] refer to Figure 5C , the photoresist PR may be removed, and the first auxiliary layer 31 may be formed to cover the 1-1 spacer 21-a, the 1-2 spacer 21-b, and the 1-3 spacer 21-c and the display panel 10. For example, the first auxiliary layer 31 may be disposed on the top and side surfaces of the 1-1 spacer 21-a, the 1-2 spacer 21-b, and the 1-3 spacer 21-c and the top surface of the display panel 10.

[0090] The first auxiliary layer 31 may include an opening 31-OP disposed between the 1-1 separator 21-a, the 1-2 separator 21-b, and the 1-3 separator 21-c. The opening 31-OP of the first auxiliary layer 31 may be a blind hole that does not penetrate the first auxiliary layer 31. The width 31W of the opening 31-OP of the first auxiliary layer 31 may be smaller than the distance S1 between the 1-1 separator 21-a, the 1-2 separator 21-b, and the 1-3 separator 21-c adjacent to each other. For example, the width 31W of the opening 31-OP of the first auxiliary layer 31 may be smaller than the distance S1 between the 1-1 separator 21-a and the 1-2 separator 21-b. According to an embodiment, in a certain direction, the distance S1 between the 1-1 separator 21-a and the 1-2 separator 21-b may be equal to the sum of the width 31W of the opening 31-OP and the thickness T1 of the first auxiliary layer 31 on the side surface of the 1-1 separator 21-a and the side surface of the 1-2 separator 21-b respectively facing the opening 31-OP of the first auxiliary layer 31.
