Description

CROSS-REFERENCE TO RELATED APPLICATION(S) This application is a continuation application, claiming priority under § 365(c), of an International application No. PCT/KR2022/012604, filed on Aug. 23, 2022, which is based on and claims the benefit of a Korean patent application number 10-2021-0110926, filed on Aug. 23, 2021, in the Korean Intellectual Property Office, the disclosure of which is incorporated by reference herein in its entirety. TECHNICAL FIELD The disclosure relates to a display module and an electronic device including the same. More particularly, the disclosure relates to a display module capable of securing an interval between patterns without increasing the width of connection members, and an electronic device including the same. BACKGROUND ART A display module may be a device for displaying visual information. A display module may be a device for converting electric signals processed by an electronic device into visual information. A display module may be electrically connected to a printed circuit board disposed inside an electronic device. As a result of the decreasing size of electronic devices and the emergence of new formfactors (for example, foldable, rollable electronic devices), inner spaces of electronic devices in which components can be mounted have become narrower. Accordingly, the free space that may be occupied by a display module and a constituent element connected to the display module is gradually reduced. Therefore, a need exists for a display module capable of securing an interval between patterns without increasing the width of connection members, and an electronic device including the same. The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure. DISCLOSURE Technical Problem There may be various methods for connecting a display module to a printed circuit board of an electronic device. For example, a connection member made of a flexible material may be used to connect a display module to a printed circuit board of an electronic device. When multiple connection members are used, the connection members may be electrically connected. Multiple conductive patterns formed on connection members may be electrically connected to each other such that multiple connection members are electrically connected, thereby electrically connecting a display module and a printed circuit board. Meanwhile, material that constitute patterns formed on connection members may be eluted for various reasons. If the interval between pattern is narrow, a short may occur between the patterns due to elution. Such a short may degrade the connection between the display module and the printed circuit board. The narrow inner mounting space of the electronic device limits any increase in the width of the connection members in order to increase the interval between the patterns. Aspects of the disclosure are to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the disclosure is to provide a display module capable of securing an interval between patterns without increasing the width of connection members, and an electronic device including the same. Additional aspects will be set forth in part in the description which follows and, in part, will be apparent from the description, or may be learned by practice of the presented embodiments. Technical Solution In accordance with an aspect of the disclosure, an electronic device is provided. The electronic device includes a display panel, a first connection member which includes multiple wires electrically connected to the display panel and on which a display driver integrated circuit (DDIC) configured to control the display panel is disposed, a first contact point part which includes multiple first pads electrically connected to some of the wires included in the first connection member and arranged in a first direction and is disposed on the first connection member, a second contact point part which includes multiple second pads electrically connected to other wires included in the first connection member and arranged in the first direction and is spaced apart from the first contact point part in a second direction perpendicular to the first direction and disposed on the first connection member, a second connection member which includes a second layer laminated on the first layer and multiple wires arranged on each of the layers and is disposed adjacent to the first connection member, a third contact point part which includes multiple third pads electrically connected to some of the wires included in the second connection member and arranged in the first direction and is disposed on the first layer of the second connection member to be connected to the first
