The present disclosure relates to a display apparatus including a display panel and a tiling coupler. The display apparatus can include a display panel; a back frame configured to attach to a wall structure by a fixing element; a height adjustment element joined to the back frame, including a permanent magnet and adjusting a height; and a position adjustment element fixed to a rear surface of the display panel, including a magnetic material mounted by a magnetic force of the height adjustment element, and adjusting a position on a plane defined by the height adjustment element.

Display apparatus

A display apparatus according to the present disclosure can include a display panel; a back frame configured to attach to a wall structure by a fixing element; a height adjustment element joined to the back frame, including a permanent magnet and adjusting a height; a position adjustment element fixed to a rear surface of the display panel, including a magnetic material mounted by a magnetic force of the height adjustment element, and adjusting a position on a plane defined by the height adjustment element; a position limiter engaged between the position adjustment element and the height adjustment element; a sound generating device disposed at a rear surface of the display panel and having a latch holder; a middle frame disposed between the height adjustment element and the position adjustment element, and including a space receiving the sound generating device; and a latch disposed to engage with the latch holder.

Discussed is a glass light guide plate that is used in a back light unit of a display device. Some features of the glass light guide plate for the back light unit can be improved by optimizing a relationship between a direction of a bubble inside the glass light guide plate and a light source, the sizes of the bubble and a light guide pattern, and so on, and by optimizing an arrangement density of light guide patterns in each region, a kind of light guide pattern ink (IR-curable ink), a curing condition, a refractive index, and so on to be suitable for the material of the glass light guide plate.
