Abstract: A display device includes a substrate including an active area having pixels and a non-active area including a pad region. A pad electrode is disposed in the pad region and includes a first pad electrode and a second pad electrode disposed on the first pad electrode. A first insulating pattern is interposed between the first and second pad electrodes. In a plan view, the first insulating pattern is positioned inside the first pad electrode, and a portion of the second pad electrode overlapping the first insulating pattern protrudes further from the substrate in a thickness direction than a portion of the second pad electrode not overlapping the first insulating pattern. The second pad electrode directly contacts a portion of the upper surface of the first pad electrode. In a plan view, an area of the second pad electrode is greater than an area of the first pad electrode.

Abstract: A backlight device for use in a display device includes a light source device and a light diffusion member. The light source device includes a plurality of light sources. The light diffusion member includes a light transmission body and reflectors. The light transmission body includes a light receiving surface facing a first one of the light sources for receiving the light emitted from the first light source and a light output surface facing away from the light receiving surface for outputting the light transmitted through the light transmission body. The reflectors are attached to the light transmission body and include first and second reflection surfaces oriented such that the light received from the first light source through the light receiving surface is reflected by the first and second reflection surfaces while the light passes through the light transmission body toward the light output surface.
