Abstract

A display apparatus includes a first substrate and a second substrate opposing to the first substrate. The first substrate includes a transmission area in which a shutter unit is disposed and an emission area in which an organic light emitting diode is disposed. The shutter unit includes a first shutter electrode, a second shutter electrode, and a shutter layer interposed between the first and second shutter electrodes. The organic light emitting diode includes a pixel electrode, a common electrode, and a light-emitting layer interposed between the pixel and common electrodes. At least one of the first and second shutter electrodes is connected to the common electrode of the organic light emitting diode.

First claim

What is claimed is:

1. A display apparatus comprising:
a display panel comprising a first substrate and a second substrate opposing to the first substrate, wherein the display panel has a first surface and a second surface and comprises a transmission area transmitting a light and an emission area in which a pixel circuit and an organic light emitting diode that is connected to the pixel circuit are disposed;
a shutter film comprising a first shutter electrode, a second shutter electrode, and a shutter layer disposed between the first and second shutter electrodes and disposed on a second surface of the first substrate;
a main driving circuit configured to generate a panel driving voltage to drive the display panel and a shutter driving voltage to drive the shutter film;
a first flexible circuit board comprising a first area that is disposed on a first surface of the first substrate and a second area that is disposed on the second surface of the first substrate, and configured to transfer the panel driving voltage to the display panel; and
a second flexible circuit board connected to the first flexible circuit board and the shutter film, and configured to transfer the shutter driving voltage to the shutter film.

2. The display apparatus of claim 1 , further comprising:
a printed circuit board on which the main driving circuit is mounted and disposed on the second surface of the first substrate,
wherein the first flexible circuit board connects the printed circuit board and the display panel, and the second flexible circuit board connects the printed circuit board and the shutter film.

3. The display apparatus of claim 1 , wherein the main driving circuit is mounted on the first flexible circuit board, a first end portion of the first flexible circuit board is connected to the display panel, and a second end portion of the first flexible circuit board is connected to the first flexible circuit board.
