Abstract

A display panel includes a first substrate, a second substrate, a quarter wavelength phase retarder, and a linear polarizer. The first substrate has a light emitting element disposed on the first substrate. The opposite panel is disposed opposite to the first substrate. The quarter wavelength phase retarder is disposed between the first substrate and the second substrate. The linear polarize is disposed at a side of the second substrate opposite to the quarter wavelength phase retarder.

Claims (10)

1. A display panel, comprising:

a first substrate having a light emitting element disposed on said first substrate;

a second substrate disposed opposite to the first substrate, and the second substrate having two main surfaces opposite to each other;

a quarter wavelength phase retarder integrated formed with the second substrate, and disposed on one of the main surfaces, wherein the quarter wavelength phase retarder has birefringence property, and the second substrate does not have the birefringence property; and

a linear polarizer, wherein the second substrate is present between the linear polarizer and the first substrate.

2. The display panel of claim 1 , wherein the quarter wavelength phase retarder is disposed between the second substrate and the first substrate.

3. The display panel of claim 1 , wherein the quarter wavelength phase retarder is disposed between the linear polarizer and the second substrate.

4. The display panel of claim 1 , wherein the quarter wavelength phase retarder and the second substrate are made from glass.

5. The display panel of claim 1 , wherein a thickness of the quarter wavelength phase retarder is about 0.01 mm.

6. The display panel of claim 1 , wherein the first substrate is an active-matrix organic light emitting diode substrate or a passive-matrix organic light emitting diode substrate.
