Abstract: A method of forming a single-crystal group-III nitride is provided in the present invention. In some embodiments, the method includes the following steps. First, a molybdenum disulfide (MoS2) is formed on a remote substrate. Then, the MoS2 is transferred onto a substrate. Next, a sputtering operation is performed to epitaxially grow a single-crystal group-III nitride layer on the MoS2, so as to form the single-crystal group-III nitride layer on the substrate such as a Si substrate or a flexible substrate.

Abstract: A display device includes a supporting frame, a display panel, an optical film assembly, and a light-penetrated adhesive member. The supporting frame includes a first supporting portion, and the display panel is disposed on the supporting frame. The display panel includes a pixel region and a non-pixel region, and the non-pixel region is disposed outside of the pixel region. The optical film assembly is partially disposed between the first supporting portion and the display panel. The light-penetrated adhesive member is disposed between the first supporting portion of the supporting frame and the optical film assembly. The light-penetrated adhesive member includes a first portion disposed corresponding to the non-pixel region and a second portion disposed corresponding to the pixel region. The configuration can achieve the narrow border design, provide a sufficient structural strength, or improve the light leakage or shadow issue at the edge of the active area.
