1. A polymer dispersed liquid crystal (PDLC) display, comprising:

a rear substrate over which a thin film transistor (TFT), a first electrode, and a second electrode are formed;

a front substrate apart from the rear substrate and having a first black matrix formed thereon corresponding to a region where the TFT is formed;

a PDLC layer disposed below the first black matrix and formed between the front and rear substrates;

a light source disposed on one side of the PDLC layer and configured to provide light to the side of the PDLC layer; and

a first reflection plate formed on the other side of the PDLC layer and configured to reflect light incident via the PDLC layer,

wherein the light source comprises a second black matrix formed on the front substrate, a second reflection plate formed on the second black matrix, and a light-emitting layer formed on the second reflection plate which is configured to reflect light emitted from the light-emitting layer to the PDLC layer.

2. The PDLC display of claim 1 , wherein the light source comprises a self-illuminant.

3. The PDLC display of claim 2 , wherein the self-illuminant comprises an organic electroluminescent light-emitting diode (OLED).

4. The PDLC display of claim 1 , wherein the light-emitting layer is formed on the second black matrix inclinedly with respect to the front substrate.

5. The PDLC display of claim 1 , wherein the layer is formed on the second black matrix vertically to the front substrate.

6. The PDLC display of claim 1 , further comprising an indium tin oxide (ITO) layer formed on a front surface of the light-emitting layer and configured to protect the light-emitting layer.

7. The PDLC display of claim 6 , wherein the ITO layer is used as an electrode for applying a power source to the light-emitting layer.

8. The PDLC display of claim 1 , wherein a pixel electrode and a common electrode of the rear substrate generate a horizontal electric field in the PDLC layer.

9. The PDLC display of claim 8 , wherein the PDLC layer scatters lateral light provided from the light source, and provides the scattered light to the first reflection plate when a voltage is applied between the pixel electrode and the common electrode.

10. The PDLC display of claim 8 , wherein the PDLC layer blocks lateral light provided from the light source when a voltage is not applied between the pixel electrode and the common electrode.

11. The PDLC display of claim 1 , wherein the PDLC layer comprises:

a polymer matrix;

micro liquid crystal droplets dispersed within the polymer matrix; and

liquid crystal molecule particles intervened within the micro liquid crystal droplets in a capsule shape.

12. The PDLC display of claim 11 , wherein the PDLC layer further comprises pigment particles added to the polymer matrix and configured to represent colors.

13. The PDLC display of claim 11 , further comprising walls formed on both sides of the PDLC layer and configured for receiving of the PDLCs.
