Exemplary embodiments relate generally to a display device and, more specifically, to a display device including a conductive film package.
A flat panel display device is used as a display device to replace a cathode ray tube display device due to its light weight and slim structure. The flat panel display device includes a liquid crystal display device and an organic light emitting display device, for example.
The display device may include a lower substrate, an upper substrate, and a plurality of pad electrodes. The pad electrodes may be electrically connected to an external device, and may be arranged in a pad area of the lower substrate in a first direction while being spaced apart from each other. A length of the pad area in a second direction perpendicular to the first direction may typically be reduced in order to reduce a dead space of the display device. In this case, a length of each of the pad electrodes in the second direction may also be reduced. An anisotropic conductive film and a flexible printed circuit board (for example, a chip on film) may be disposed on the pad electrodes in order to be electrically connected to the external device. The anisotropic conductive film may bond the pad electrode to the flexible printed circuit board, and the pad electrode may be electrically connected to the flexible printed circuit board through the conductive balls included in the anisotropic conductive film. However, it is generally difficult to manufacture the anisotropic conductive film having a length of 0.6 mm or less in the second direction. In other words, the reduced length of the pad area (for example, 0.5 mm or less) causes difficulty in forming the anisotropic conductive film on the pad electrode.
The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate exemplary embodiments of the invention, and together with the description serve to explain the inventive concepts.
FIG. 1 is a plan view showing a display device according to an exemplary embodiment.
FIG. 2 is a perspective view showing the display device of FIG. 1.
In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of various exemplary embodiments or implementations of the invention. As used herein “embodiments” and “implementations” are interchangeable words that are non-limiting examples of devices or methods employing one or more of the inventive concepts disclosed herein. It is apparent, however, that various exemplary embodiments may be practiced without these specific details or with one or more equivalent arrangements. In other instances, well-known structures and devices are shown in block diagram form in order to avoid unnecessarily obscuring various exemplary embodiments. Further, various exemplary embodiments may be different, but do not have to be exclusive. For example, specific shapes, configurations, and characteristics of an exemplary embodiment may be used or implemented in another exemplary embodiment without departing from the inventive concepts.
Unless otherwise specified, the illustrated exemplary embodiments are to be understood as providing exemplary features of varying detail of some ways in which the inventive concepts may be implemented in practice. Therefore, unless otherwise specified, the features, components, modules, layers, films, panels, regions, and/or aspects, etc. (hereinafter individually or collectively referred to as “elements”), of the various embodiments may be otherwise combined, separated, interchanged, and/or rearranged without departing from the inventive concepts.
The use of cross-hatching and/or shading in the accompanying drawings is generally provided to clarify boundaries between adjacent elements. As such, neither the presence nor the absence of cross-hatching or shading conveys or indicates any preference or requirement for particular materials, material properties, dimensions, proportions, commonalities between illustrated elements, and/or any other characteristic, attribute, property, etc., of the elements, unless specified. Further, in the accompanying drawings, the size and relative sizes of elements may be exaggerated for clarity and/or descriptive purposes. When an exemplary embodiment may be implemented differently, a specific process order may be performed differently from the described order. For example, two consecutively described processes may be performed substantially at the same time or performed in an order opposite to the described order. Also, like reference numerals denote like elements.
