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.

Display with light absorber round optical element

A display apparatus includes: a display panel including: a transmissive area configured to transmit light incident thereon, and an emissive area configured to emit light, a light-controlling device on a rear surface of the display panel, the light-controlling device being configured to have a light transmission mode for transmitting the incident light and a light-blocking mode for blocking the incident light, the light-controlling device including: a first substrate and a second substrate facing each other, a transmission controller between the first substrate and the second substrate, the transmission controller overlapping the transmissive area, and a vibration generator between the first substrate and the second substrate, the vibration generator overlapping the emissive area.

Display apparatus

A light controlling apparatus and a transparent display device comprising the same are discussed, in which picture quality can be prevented from being deteriorated by a voltage drop. The light controlling apparatus can include a first base film including a first lower pad arranged at a first side edge on one surface and a second lower pad arranged at a second side edge on the one surface; a second base film including a first upper pad arranged at a third side edge on one surface facing one surface of the first base film and a second upper pad arranged at a fourth side edge on the one surface; and a flexible circuit board including driving voltage lines electrically connected with the first and second lower pads and common voltage lines electrically connected with the first and second upper pads.

Light controlling apparatus and transparent display device comprising the same

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.
