Abstract: A front emission type display device is provided. In the display device, light generated by a light-emitting element which is disposed on a first substrate can be emitted to the outside through a color filter and a second substrate, so that an image can be realized on an outer surface of the second substrate.

Abstract: A display device serving as a mirror in a non-display state is provided. The display device may include a reflective pattern and a half-mirror layer which are disposed on an upper substrate opposite to a lower substrate. The half-mirror layer may be disposed side by side with the reflective pattern. Thereby, a discontinuous appearance of the reflective image may be reduced, and the degradation of the reflective image due to the diffraction of the light may be prevented or reduced.

Abstract: A display device is provided. The display device includes a changeable reflective structure having a first changeable electrode, a changeable reflecting layer and a second changeable electrode, which are sequentially stacked on an upper substrate opposite a lower substrate. In the display device, the reflectance of the changeable reflecting layer may be adjusted by controlling a voltage applied to the first changeable electrode and the second changeable electrode according to a state of a light-emitting structure which is disposed on an emitting area of the lower substrate. Thus, in the display device, a decrease of the color sense by the reflection of external light in a display state may be prevented, and the reflective area may have sufficient reflectance for serving as a mirror in a non-display state.

Abstract: Disclosed is a method of fabricating a single crystal colloidal monolayer on a substrate. The method includes preparing a pair of adhesive substrates, arranging powder particles between the substrates, and uniaxially rubbing one of the substrates in any one direction to allow the particles to be close-packed between the substrates, thereby forming a single crystal monolayer.
