[0044] By referring to the detailed description and the accompanying drawings of the embodiments, it is easier to understand the various aspects of some embodiments of the present disclosure and the method for realizing it. The described embodiments are provided as examples so that the present disclosure will be thorough and complete, and the various aspects of the present disclosure will be fully conveyed to those skilled in the art. Therefore, redundant, irrelevant or irrelevant to the description of the embodiments, or unnecessary processes, elements and techniques for a person of ordinary skill in the art to fully understand the various aspects of the present disclosure can be omitted. Unless otherwise stated, in the entire drawings and written descriptions, the same reference numerals, characters or combinations thereof represent the same elements, and therefore, their repeated descriptions can be omitted.
[0045] The embodiments described may have various modifications and may be embodied in different forms, and should not be construed as being limited to the embodiments shown herein. The "can", "may" or "may not" used in the description of the embodiments corresponds to one or more embodiments of the present disclosure. The present disclosure encompasses all modifications, equivalences and substitutions within the scope of the ideas and techniques of the present disclosure. In addition, each of the features of the various embodiments of the present disclosure may be combined with each other in part or in whole, and various interlocks and drives in technology are possible. Each embodiment may be implemented independently of one another, or may be implemented together in combination.
[0046] In the drawings, the relative sizes of elements, layers, and regions may be exaggerated for clarity and / or descriptive purposes. In addition, the use of cross-hatching and / or shading in the drawings is generally provided to clarify the boundaries between adjacent elements. Therefore, the presence or absence of cross-hatching or shading does not convey or indicate any preference or requirement for specific materials, material properties, dimensions, proportions, commonality between the elements shown, and / or any other features, attributes, characteristics, etc. of the elements, unless otherwise stated.
[0047] Various embodiments are described herein with reference to cross-sectional views, which are schematic diagrams of embodiments and / or intermediate structures. Thus, variations in the illustrated shapes, for example due to manufacturing techniques and / or tolerances, are contemplated. In addition, the specific structural or functional descriptions disclosed herein are merely illustrative, for the purpose of describing embodiments according to the concepts of the present disclosure. Therefore, the embodiments disclosed herein should not be interpreted as being limited to the shapes of the elements, layers, or regions shown, but rather include shape deviations caused by, for example, manufacturing.
[0048] For ease of explanation, spatially relative terms such as "under", "below", "lower", "lower side", "below", "above", "upper", and "upper side" may be used herein to describe the relationship of one element or feature to (multiple) another element or (multiple) features, as shown in the figures. It will be understood that the spatially relative terms are intended to cover different orientations of the device in use or operation other than the orientation depicted in the drawings. For example, if the device in the drawings is rotated, the element described as being "under" or "under" or "below" other elements or features will then be oriented to be "above" the other elements or features. Therefore, the example terms "under" or "below" may include both orientations of "above" and "below". The device may be oriented in other ways (e.g., rotated by 90 degrees or in other orientations), and the spatially relative terms used herein are interpreted accordingly. Similarly, when a first part is described as being arranged "on" a second part, this means that the first part is arranged on the upper or lower side of the second part based on the direction of gravity, and is not limited to the upper side of the second part.
[0049] In addition, the phrase "in a plan view" refers to when the object portion is observed from above, and the phrase "in a schematic cross-sectional view" refers to when a schematic cross-section obtained by vertically cutting the object portion is observed from the side. The term "overlap" or "overlapping" means that the first object can be above or below or on one side of the second object, and vice versa. In addition, the term "overlap" may include stacking, facing or facing, extending on, covering or partially covering, or any other suitable term that a person of ordinary skill in the art will understand and understand. The expression "non-overlapping" may include meanings such as "away from" or "separated" or "offset" and any other suitable equivalents that a person of ordinary skill in the art will understand and understand. The terms "facing" and "facing" may mean that the first object may be directly or indirectly opposite to the second object. In the case where a third object is between the first object and the second object, the first object and the second object may be understood to be indirectly opposite to each other, although still facing each other.
[0050] It will be understood that when an element, layer, region, or component is referred to as being "formed on," "on," "connected to," or "(operably or communicatively) coupled to" another element, layer, region, or component, the element, layer, region, or component may be directly formed on, directly on, directly connected to, or coupled to, or indirectly formed on, indirectly on, indirectly connected to, or coupled to, such that one or more intervening elements, layers, regions, or components may be present. . In addition, this can be collectively referred to as direct or indirect coupling or connection and integral or non-integrated coupling or connection. For example, when a layer, region or component is referred to as "electrically connected" or "electrically coupled" to another layer, region or component, the layer, region or component can be directly electrically connected or coupled to another layer, region and / or component, or there can be one or more intervening layers, regions or components. The one or more intervening components may include switches, resistors, capacitors, and the like. In describing embodiments, the expression of connection indicates electrical connection unless explicitly described as a direct connection, and "directly connected / directly coupled" or "directly on..." means that one component is directly connected or coupled to another component, or directly on another component, without intervening components.
[0051] In addition, in this specification, when a part of a layer, film, region or plate, etc. is formed on another part, the formation direction is not limited to the upward direction, but includes forming the part on the side surface or in the downward direction. On the contrary, when a part of a layer, film, region or plate, etc. is formed "below" another part, this includes not only the case where the part is "directly below" another part, but also the case where another part exists between the part and the other part. At the same time, other expressions describing the relationship between components (such as "between...", "immediately between..." or "adjacent to..." and "directly adjacent to...") can be interpreted similarly. It will be understood that when an element or layer is referred to as "between" two elements or layers, the element or layer can be the only element or layer between the two elements or layers, or one or more intermediate elements or layers may also exist.
[0052] For the purposes of this disclosure, expressions such as "at least one of ...," or "any one of ...," or "one or more of ...," when following a list of elements, modify the entire list of elements and do not modify the individual elements of the list. For example, "at least one of X, Y, and Z" and "at least one selected from the group consisting of X, Y, and Z" can be interpreted as any combination of only X, only Y, only Z, two or more of X, Y, and Z, such as, for example, XYZ, XY, YZ, and XZ, or any variation thereof. Similarly, expressions such as "at least one of A and B" may include A, B, or A and B. As used herein, "or" generally means "and / or," and the term "and / or" includes any and all combinations of one or more of the associated listed items. For example, the expression "A and / or B" may include A, B, or A and B. Similarly, expressions such as "at least one of ...," "a plurality of," "one of ...," and other prepositional phrases, when preceding / following a list of elements, modify the entire list of elements and do not modify the individual elements in the list.
[0053] It will be understood that, although the terms "first", "second", "third", etc. can be used to describe various elements, components, areas, layers and / or sections in this article, these elements, components, areas, layers and / or sections should not be limited by these terms. These terms do not correspond to a specific order, position or priority, and are only used to distinguish an element, member, component, area, region, layer, section or part from another element, member, component, area, region, layer, section or part. Therefore, without departing from the spirit and scope of the present disclosure, the first element, component, area, layer or section described below can be referred to as the second element, component, area, layer or section. Describing an element as a "first" element may not require or imply the presence of a second element or other elements. The terms "first", "second", etc. can also be used to distinguish different categories or groups of elements in this article. For simplicity, the terms "first", "second", etc. can respectively represent "first category (or first group)", "second category (or second group)", etc.
[0054] In the example, the x-axis, y-axis and / or z-axis are not limited to the three axes of the rectangular coordinate system and can be interpreted in a broader sense. For example, the x-axis, y-axis and z-axis can be perpendicular to each other, or can represent different directions that are not perpendicular to each other. The same applies to the first direction DR1, the second direction DR2 and / or the third direction DR3.
[0055] The terms used herein are only used for the purpose of describing the embodiments and are not intended to limit the present disclosure. As used herein, the singular forms "a" and "an" are intended to also include the plural forms, and the plural forms are also intended to include the singular forms, unless the context clearly indicates otherwise. It will also be understood that the terms "comprises, comprising", "have, having" and "includes, including" when used in this specification specify the presence of the features, integers, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or groups thereof.
[0056] As used herein, the terms "substantially", "approximately", "approximately" and similar terms are used as approximate terms rather than terms of degree, and are intended to account for the inherent deviations of measured or calculated values recognized by those of ordinary skill in the art. For example, "substantially" may include a range of + / -5% of the corresponding value. As used herein, taking into account the measurement in question and the errors associated with the measurement of a particular quantity (i.e., the limitations of the measurement system), "approximately" or "approximately" includes the stated value and means within the acceptable deviation range of the particular value determined by those of ordinary skill in the art. For example, "approximately" may mean within one or more standard deviations, or within ±30%, ±20%, ±10%, ±5% of the stated value. In addition, "may" is used when describing embodiments of the present disclosure to refer to "one or more embodiments of the present disclosure".
[0057] Unless otherwise defined, all terms (including technical and scientific terms) used herein 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 / or this specification, and should not be interpreted as an idealized or overly formal meaning unless explicitly defined herein.
[0058] Figure 1 is a plan view showing a display device according to one or more embodiments of the present disclosure.
[0059] Reference Figure 1 , the display device DD according to one or more embodiments of the present disclosure may be divided into a display area DA and a non-display area NDA. The display area DA may be an area capable of displaying an image by generating light or by adjusting the transmittance of light provided from an external light source. The non-display area NDA may be an area where an image is not displayed. The non-display area NDA may be located around the display area DA. For example, the non-display area NDA may surround the display area DA.

However, the color of the light emitted by the first sub-pixel SPX1, the second sub-pixel SPX2, and the third sub-pixel SPX3 is not limited thereto. In addition, the number of the first sub-pixel SPX1, the second sub-pixel SPX2, and the third sub-pixel SPX3 is shown as three, but the number is not limited thereto. For example, each of the plurality of pixels PX may also include a fourth sub-pixel emitting white light.
[0063] The plurality of pixels PX may be positioned in a matrix along a first direction DR1 and a second direction DR2 crossing the first direction DR1. Thus, each of the first subpixel SPX1, the second subpixel SPX2, and the third subpixel SPX3 may be arranged in a matrix along the first direction DR1 and the second direction DR2.
[0064] The pixel driver may be located in the non-display area NDA.

[0076] The fourth transistor T4 may supply the initialization voltage VINT to the fourth node N4 during the activation period of the third gate signal GI.

[0078] The fifth transistor T5 may supply the driving voltage ELVDD to the first electrode of the first transistor T1 during an activation period of the emission control signal EM.
