Polarizer, display substrate, display panel having the same and method of manufacturing the same
A display panel includes a light blocking pattern and a polarizer. The light blocking pattern is disposed on a base substrate. A plurality of opening areas is defined based on the light blocking pattern. The polarizer includes a plurality of linear patterns spaced apart from each other. The plurality of opening areas includes a color area transmitting color light and a white area transmitting white light. The polarizer overlaps the color area and the white area.
1. A display panel, comprising:
a first display substrate comprising a light blocking pattern disposed on a first base substrate and a plurality of opening areas being defined based on the light blocking pattern;
a first polarizer comprising a plurality of first linear patterns spaced apart from each other;
a second display substrate opposite to the first display substrate, the second display substrate comprising a switching device disposed on a second base substrate; and
a second polarizer comprising a plurality of second linear patterns spaced apart from each other and overlapping the first polarizer, wherein:
the plurality of opening areas comprise a color area configured to transmit color light and a white area configured to transmit white light; and
the first polarizer and the second polarizer overlap the color area and the white area.
2. The display panel of claim 1 , wherein:
the color area comprises a color filter configured to transmit red light, green light, and blue light; and
the color filter is not formed in the white area.
3. The display panel of claim 1 , wherein:
the first polarizer and the second polarizer comprise at least one material selected from the group consisting of aluminum (Al), gold (Au), silver (Ag), copper (Cu), chrome (Cr), iron (Fe), and nickel (Ni).
4. The display panel of claim 1 , wherein the light blocking pattern comprises a black coloring agent and organic material.
5. The display panel of claim 1 , wherein the first polarizer and the second polarizer are not disposed on an area on which the light blocking pattern is disposed.
6. The display panel of claim 1 , wherein:
the light blocking pattern comprises a reflection pattern comprising metal; and
the reflection pattern and the first polarizer are disposed on a same layer.
7. The display panel of claim 6 , wherein the reflection pattern overlaps the switching device.
8. The display panel of claim 7 , wherein the reflection pattern comprises at least one material selected from the group consisting of aluminum (Al), gold (Au), silver (Ag), copper (Cu), chrome (Cr), iron (Fe), and nickel (Ni).
9. The display panel of claim 1 , further comprising a column spacer disposed on the light blocking pattern.
