a reflection sheet formed on an upper surface of the printed circuit board;

one or more light emitting units formed on the reflection sheet;

a plurality of reflection patterns formed on the reflection sheet;

a resin layer formed on the reflection sheet;

a diffusion sheet formed on the resin layer;

an optical pattern formed on a lower surface of the diffusion sheet;

a liquid crystal display panel formed on the diffusion sheet; and

a room mirror disposed on the liquid crystal display panel and configured to transmit and reflect light;

wherein a pattern density of the plurality of reflection patterns increases as a distance from the light emitting units increases,

wherein the optical pattern functions to partially shield and diffuse light emitted from the light emitting units,

wherein the light emitting units, the plurality of reflection patterns, and the optical pattern are embedded in the resin layer;

wherein the optical pattern comprises a diffusion pattern and a light shielding pattern;

wherein the diffusion pattern, the light shielding pattern, and the light emitting units are buried in the resin layer;

wherein the diffusion pattern comprises:

a first diffusion part covered by the light shielding pattern; and

a second diffusion part covered by the resin layer;

wherein the light shielding comprises:

a first shielding part disposed on a lower surface of the first diffusion part; and

a second shielding part disposed on the lower surface of the diffusion sheet; and

wherein a side surface of a reflection pattern of the plurality of reflection patterns is directly contacted with a light emitting unit of the one or more light emitting units.

2. The display room mirror of claim 1 , further comprising an ECM module formed on a rear surface of the room mirror.

3. The display room mirror of claim 2 , wherein the ECM module comprises: a first transparent substrate and a second transparent substrate which are opposed to each other at a predetermined distance; a transparent electrode and a conductive reflection layer which are formed on an opposed surface of the first and second transparent substrates, respectively; and

an electrochromic layer interposed between the transparent electrode and the conductive reflection layer.

4. The display room mirror of claim 3 , wherein the electrochromic layer comprises: an electrolytic layer interposed between the transparent electrode and the conductive reflection layer; and an electrochromic coating layer formed on one surface or both surfaces of the electrolytic layer.

5. The display room mirror of claim 1 , wherein the room mirror is formed of a half mirror.
