Embodiments of a fastener and a display of a portable computer using the same and methods thereof can reduce a thickness, cost or weight of a display panel. The fastener can include at least a pair of columns spaced apart from each other, a connection for connecting the pair of columns, and first and second catching jaws that can be formed on different portions of the fastener (e.g., lateral sides) such that a part to be coupled can be caught thereto. The first and second catching jaws can be separated by a prescribed height. A front and rear case of a display of a portable computer include a catching hook and the fastener, respectively, so an inverter or the like can be secured in the display.
