    Abstract: A display device includes a display panel including first to fourth panel pads and a connection board including first to fourth connection board pads coupled to the first to fourth pads, respectively. The first and second panel pads are electrically connected to each other, and the third and fourth panel pads are electrically connected to each other. The connection board includes a driving circuit which generates a first test result signal based on a first panel test signal transmitted to the first connection board pad and a first panel feedback signal received from the second connection board pad, generates a second test result signal based on a second panel test signal transmitted to the third connection board pad and a second panel feedback signal received from the fourth connection board pad, and sequentially outputs the first and second test result signals as a test result signal.

    Abstract: A display device includes a backlight unit generating light and a display panel displaying an image using the light from the backlight unit. The backlight unit includes a circuit board, a plurality of light emitting devices, a light guide member including a light incident surface, and a guide member disposed between a surface of the circuit board and the light incident surface. The guide member uniformly maintains a distance between the light incident surface and the light emitting devices. Thus, a light loss is reduced.

    Abstract: A display device includes a display substrate, a main circuit board, and first and second connection circuit boards. The display substrate includes a base layer, an insulating layer on the base layer, a first signal line on the base layer, a second signal line on the base layer, a first pad exposed from the insulating layer and connected to the first signal line, and a second pad connected to a side surface of the second signal line and disposed on a side surface and a bottom surface of the base layer. The first connection circuit board electrically connects the first pad and the main circuit board, and the second connection circuit board electrically connects the second pad and the main circuit board.

    Abstract: A light emitting package includes a circuit board, a light emitting chip disposed on the circuit board and electrically connected to the circuit board, a resin layer disposed on the light emitting chip, and a fluorescent layer disposed on the resin layer. The light emitting chip is disposed between the resin layer and the circuit board. The resin layer is disposed between the light emitting chip and the fluorescent layer. For a light, a refractive index of the resin layer is smaller than a refractive index of the light emitting chip and is larger than a refractive of the fluorescent layer.
