[0037] The present disclosure will now be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the present disclosure are shown. However, the present disclosure may be implemented in different forms and should not be construed as being limited to the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure is thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.
[0038] In order to describe the embodiments of the present disclosure, some parts that are not related to the description may not be provided, and the same reference numerals refer to the same elements throughout the specification.
[0039] When a layer, film, zone, substrate or region is referred to as "on" another layer, film, zone, substrate or region, it can be directly on another film, zone, substrate or region, or there can be an intermediate film, zone, substrate or region between them. On the contrary, when a layer, film, zone, substrate or region is referred to as "directly" on another layer, film, zone, substrate or region, there can be no intermediate layer, film, zone, substrate or region between them. In addition, when a layer, film, zone, substrate or region is referred to as "below" or "below" another layer, film, zone, substrate or region, it can be directly below or below another layer, film, zone, substrate or region, or there can be an intermediate layer, film, zone, substrate or region between them. On the contrary, when a layer, film, zone, substrate or region is referred to as "directly" "below" another layer, film, zone, substrate or region, there can be no intermediate layer, film, zone, substrate or region between them. In addition, "above ..." or "on ..." can include being positioned on or below an object, and does not necessarily imply a direction based on gravity.
[0040] For ease of description, spatially relative terms "below", "under", "lower", "above", "upper", etc. may be used herein to describe the relationship between one element or component and another element or component shown in the drawings. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation shown in the drawings. For example, where the device illustrated in the drawings is turned over, a device positioned "below" or "beneath" another device may be placed "above" the other device. Thus, the illustrative term "below" may include both upper and lower positions. The device may also be oriented in other directions, so the spatially relative terms may be interpreted differently depending on the orientation.
[0041] Throughout the specification, when an element is referred to as being "connected" to another element, the element may be "directly connected" to the other element, or "indirectly connected" to the other element with one or more intermediate elements interposed therebetween. It will be further understood that when the terms "include" and / or "comprise" are used in this specification, they or it may specify the presence of stated features, integers, steps, operations, elements and / or components, but do not exclude the presence or addition of other features, integers, steps, operations, elements, components and / or any combination thereof.
[0042] In the accompanying drawings, the size and thickness of the elements may be exaggerated for better understanding, clarity and ease of description. However, the present disclosure is not limited to the illustrated size and thickness. In the accompanying drawings, the thickness of layers, films, panels, regions and other elements may be exaggerated for clarity. In the accompanying drawings, the thickness of some layers and regions may be exaggerated for better understanding and ease of description.
[0043] Furthermore, in the specification, the phrase "in a plan view" means when an object portion is viewed from above, and the phrase "in a schematic cross-sectional view" means when a schematic cross section taken by vertically cutting the object portion is viewed from the side.
[0044] In addition, 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" can include layers, stacks, facing or facing, extending above, covering or partially covering, or any other suitable terms that a person of ordinary skill in the art will recognize and understand. The terms "facing" and "facing" represent that the first element can be directly or indirectly opposite to the second element. In the case where a third element is between the first element and the second element, although the first element and the second element still face each other, the first element and the second element can be understood to be indirectly opposite to each other. When an element is described as "non-overlapping" with another element, this can include elements spaced apart from each other, offset from each other or separated from each other or any other suitable terms that a person of ordinary skill in the art will recognize and understand.
[0045] As used herein, "about" or "approximately" includes the stated value and means within an acceptable deviation range of the particular value determined by a person of ordinary skill in the art, 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). For example, "about" may mean within one or more standard deviations, or within ±30%, 20%, 5% of the stated value. In the specification and claims, the term "and / or" is intended to include any combination of the terms "and" and "or" for the purpose of its meaning and interpretation. For example, "A and / or B" may be understood to mean "A, B, or A and B". The terms "and" and "or" may be used in conjunction or separation and may be understood to be equivalent to "and / or". In the specification and claims, the phrase "at least one of..." is intended to include the meaning of "at least one selected from the group of..." for the purpose of its meaning and interpretation. For example, "at least one of A and B" may be understood to mean "A, B, or A and B".
[0046] Terms such as first, second, etc. can be used to describe various components, but these components should not be limited by these terms. These terms are usually only used to distinguish one element from another element. For example, without departing from the spirit and scope of the present disclosure, the first component can be referred to as the second component, or similarly, the second component can be referred to as the first component. As used herein, the singular forms of "one", "an", and "the" may be intended to also include plural forms, unless the context clearly indicates otherwise.
[0047] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as those commonly understood by those of ordinary skill in the art to which the embodiments belong. In addition, it will be further 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 will not be interpreted in an idealized or overly formal sense, unless explicitly defined as such herein.

[0120] The mold frame MF may be positioned or disposed on the outer surface of the accommodating portion ACM. For example, the mold frame MF may be positioned or disposed along the outer surface of the side wall portion SW. The surfaces of the side wall portion SW that may face each other may be defined as the inner surface of the side wall portion SW, and the outer surface of the side wall portion SW may be defined as the surface opposite to the inner surface.
[0121] The mold frame MF may be positioned or disposed under the second polarizing plate POL2 to support the display panel DP. The adhesive AD may be positioned or disposed between the mold frame MF and the display panel DP. The display panel DP may be adhered to the mold frame MF by means of the adhesive AD. For example, the adhesive AD may be positioned or disposed between the mold frame MF and the second polarizing plate POL2, and the second polarizing plate POL2 may be adhered to the mold frame MF.
[0122] The flexible circuit film FPC may be bent downward from the outside of the accommodation portion ACM along the outer surface of the accommodation portion ACM to extend downward under the accommodation portion ACM. The outer surface of the accommodation portion ACM may be defined as the outer surface of the side wall portion SW.
[0123] A portion of the side wall portion SW that may be adjacent to the flexible circuit film FPC may be defined by a first side wall portion SW1. The first side wall portion SW1 may face one side surface of the light guide panel LGP. The light source LS may be positioned or disposed on an inner surface of the first side wall portion SW1.
[0124] The flexible circuit film FPC may be bent along the outer surface of the first side wall portion SW1 outside the first side wall portion SW1. The bendable portion of the flexible circuit film FPC may be defined as a bending portion BAP. The outer surface of the first side wall portion SW1 may face the bending portion BAP.
[0125] The printed circuit board PCB and the driving chip D-IC may be positioned or disposed under the bottom BP of the accommodation part ACM. The printed circuit board PCB and the driving chip D-IC may be positioned or disposed to correspond to a portion of the flexible circuit film FPC that may be positioned or disposed under the bottom BP.
[0126] The housing CS may be positioned or disposed below the accommodating portion ACM to be connected to the lower portion of the accommodating portion ACM. The printed circuit board PCB and the driver chip D-IC may be positioned or disposed between the housing CS and the accommodating portion ACM. For example, the printed circuit board PCB and the driver chip D-IC may be positioned or disposed between the bottom BP and the housing bottom CBP.
[0127] The upper portion of the shield cover SC may contact one side of the display panel DP. The shield cover SC may be positioned or arranged to be spaced apart from the bend portion BAP in the second direction DR2 or to protrude or extend outward from the bend portion BAP to face the bend portion BAP. The bend portion BAP may face the second extension portion EX2. The bend portion BAP may be positioned or arranged between the shield cover SC and the first side wall portion SW1. The groove G may be defined in a surface of the shield cover SC facing the bend portion BAP. A portion of the bend portion BAP may be positioned or arranged in the groove G.
[0128] For example, one side of the first extension EX1 may be positioned or disposed under one side of the display panel DP to contact one side of the display panel DP. The one side of the first extension EX1 may be positioned or disposed under one side of the first polarizing plate POL1 to contact the one side of the first polarizing plate POL1.

For example, since the shield cover SC contacts the display panel DP and the conductive layer CDL may be coated on the shield cover SC, static electricity generated in the display panel DP may be discharged through the conductive layer CDL of the shield cover SC.
[0131] When the groove G is not defined in the shield cover SC, the shield cover without the groove may have a structure in which the third extension portion EX3 extends in the third direction DR3 to contact the display panel DP. The bent portion BAP may contact the shield cover SC having such a structure and push the shield cover SC to the outside.
[0132] When the shielding cover SC is pushed to the outside, a portion of the shielding cover SC that may contact the display panel DP may be separated from the display panel DP. As a result, the display panel DP may be separated from the shielding cover SC, whereby static electricity generated in the display panel DP may not be discharged through the shielding cover SC. For example, a portion of the flexible circuit film FPC may be exposed to the outside through the space between the display panel DP and the shielding cover SC, and accordingly, the user may see the flexible circuit film FPC from the outside.
[0133] However, in one embodiment, the bent portion BAP may be positioned or disposed in the groove G defined in the shield cover SC so that the bent portion BAP may not contact the shield cover SC. As a result, the bent portion BAP may not push the shield cover SC to the outside. Accordingly, the shield cover SC may maintain a state of contacting the display panel DP.
[0134] As a result, the display device DD according to the embodiment can prevent the flexible circuit film FPC from being exposed to the outside through the shield cover SC, and can discharge static electricity generated in the display panel DP.
[0135] According to an embodiment, the shield cover SC may be positioned or disposed to be spaced apart from the flexible circuit film connected to one side of the display panel in the second direction DR2 and cover the flexible circuit film so that the flexible circuit film may not be exposed to the outside.
[0136] For example, a shield cover on which a conductive material may be coated may contact one side of a display panel to discharge static electricity generated in the display panel.
