Abstract: Disclosed are a light blocking device, a method of manufacturing the same, and a transparent display device including the same, which transmit or block light by using a polymer dispersed liquid crystal (PDLC) layer. The light blocking device includes a first substrate and a second substrate facing each other, a first electrode on the first substrate, a second electrode on the second substrate, and a PDLC layer between the first electrode and the second electrode. The PDLC layer includes a droplet including liquid crystals and dichroic dyes, and the liquid crystals and the dichroic dyes are twisted with each other and aligned.

Abstract: A light emitting display apparatus can include a thin film transistor (TFT) substrate and a color filter substrate. The TFT substrate can include a plurality of pixels, where each pixel includes an emission region and a non-emission region. The color filter substrate can include an upper substrate opposite to the TFT substrate, a color filter layer on the upper substrate, and a black matrix dividing the color filter layer. The black matrix can have an eaves structure.

Abstract: A display apparatus is disclosed, which includes a display panel having a first area and a second area, a main body supporting the display panel, an auxiliary member arranged in the main body and overlapped with the first area of the display panel, and a light absorption portion arranged in the second area of the display panel to surround the first area of the display panel. Therefore, external light reflected from the auxiliary member is prevented from being re-reflected in the auxiliary member, whereby image overlap or noise may be prevented from occurring.
