[0035] The present disclosure will now be described more fully hereinafter with reference to the accompanying drawings, in which various embodiments are shown. The present disclosure may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Like reference numerals refer to like elements throughout the specification.

[0036] It will be understood that when an element is referred to as being "on" another element, it can be directly on the other element or intervening elements can be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present.

[0037] It will be understood that, although the terms "first", "second", "third", etc. can be used herein to describe various elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, "a first element", "component", "region", "layer" or "section" discussed below could be termed a second element, component, region, layer or section without departing from the teachings herein.

[0038] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. "Or" means "and / or". At least one of A and B means A or / and B. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items. It will be further understood that the terms "comprises" and / or "comprising", or "includes" and / or "including" when used in this specification, specify the presence of stated features, regions, integers, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, regions, integers, steps, operations, elements, components, and / or groups thereof.

[0039] Furthermore, relative terms such as "lower" or "bottom" and "upper" or "top" can be used herein to describe one element's relationship to another element as the device is oriented in the drawing. It will be understood that relative terms are intended to encompass different orientations of the device in addition to the orientation depicted in the drawings. For example, if the device in one of the drawings is turned over, elements described as being on the "lower" side of other elements would then be oriented on "upper" sides thereof, and vice versa. Thus, the exemplary term "lower" can encompass both an orientation of "lower" and "upper," depending on the particular orientation being referred to. Similarly, if the device in one of the drawings is turned over, elements described as "below" or "beneath" other elements would then be oriented "above" the other elements. Thus, the exemplary terms "below" or "beneath" can encompass both an orientation of "below" and "above," depending on the particular orientation being referred to.

[0040] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

[0041] Exemplary embodiments are described herein with reference to cross-sectional illustrations that are schematic illustrations of idealized embodiments. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and / or tolerances, are to be expected. Thus, embodiments described herein are not to be construed as being limited to the particular shapes of regions as illustrated herein but are to include deviations in shapes that result, for example, from manufacturing. For example, an area illustrated as a flat surface can typically have rough and / or nonlinear features. Moreover, sharp angles that are illustrated can be rounded. Thus, the regions illustrated in the figures are schematic in nature and their shapes are not intended to illustrate the precise shape of a region and are not intended to limit the scope of the present claims.

[0069] The data driving circuit DIC is disposed or mounted on the pad area PDA of the first non-display area NDA1. The data driving circuit DIC includes 1st to 1440th output terminals T1 to T1440 configured to respectively output data voltages corresponding to 1st to 1440th data lines DL1 to DL1440 of the display area DA.

[0070] The first non-display area NDA1 can include a first fan-out area FOA1, a second fan-out area FOA2, and a bending area BA between the pad area PDA and the display area DA.

[0071] In the first fan-out area FOA1, 1st to 720th fan-out lines F1 to F720 corresponding to 1st to 720th data lines DL1 to DL720 arranged in the first area A1, 721st to 1440th fan-out lines F721 to F1440 corresponding to 721st to 1440th data lines DL721 to DL1440 arranged in the second area A2, and 1st to 720th bypass fan-out lines CL1 to CL720 are arranged.

[0072] The 1st to 720th fan-out lines F1 to F720 are respectively connected to the 1st to 720th output terminals T1 to T720 of the data driving circuit DIC.

[0074] The 1st to 720th fan-out lines F1 to F720 extend and are sequentially arranged in an area adjacent to one end of the data driving circuit DIC or an area adjacent to the 1st output terminal T1.

In embodiments, the shielding electrodes can be power voltage lines VL (shown) configured to transmit a power voltage EVVDD to drive organic light emitting diodes arranged in the display area DA. Figure 3 The power voltage lines VL can be formed or defined by a metal layer different from (e.g., provided in a different layer from) the metal layer defining the first 721 fan-out lines F721 to the 1440th fan-out line F1440 or the first 1 bypass fan-out line CL1 to the 720th bypass fan-out line CL720.

[0084] In exemplary embodiments, the first 1 fan-out line F1 to the 1440th fan-out line F1440 can be formed or defined by a first gate metal layer and a second gate metal layer in different layers from each other. In one exemplary embodiment, for example, odd fan-out lines can be formed or defined by the first gate metal layer, and even fan-out lines can be formed or defined by the second gate metal layer.

[0085] The first 1 data line DL1 to the 1440th data line DL1440 can be formed or defined by a first source metal layer different from the first gate metal layer and the second gate metal layer.

[0086] The power voltage lines VL can be formed or defined by the first source metal layer.

[0087] The first 1 bypass fan-out line CL1 to the 720th bypass fan-out line CL720 arranged to cross the first 1 fan-out line F1 to the 1440th fan-out line F1440 can be formed or defined by a second source metal layer different from the first source metal layer.

[0088] The power voltage lines VL can be provided between or overlap with the fan-out lines formed by the first gate metal layer and the second gate metal layer and the bypass fan-out lines formed by the second source metal layer, such that electrical coupling between the fan-out lines and the bypass fan-out lines can be shielded.

[0089] According to an exemplary embodiment, the fan-out lines and the bypass fan-out lines are arranged to cross each other in the fan-out area adjacent to the data driving circuit such that an arrangement order of the output terminals arranged in the data driving circuit can be designed to be the same as an arrangement order of the data lines arranged in the display area, and thus a development cost for a new data driving circuit can be reduced. In such an embodiment, the fan-out lines and the bypass fan-out lines can be rearranged not to cross each other in the fan-out area adjacent to the display area such that the signal lines overlap each other, and thus an arrangement gap between the fan-out lines and the bypass fan-out lines when viewed from a plan view of a thickness direction of the display device can be reduced.
