Liquid crystal display panel having reflection electrodes improved in smooth surface morphology and process for fabrication thereof
View Patent ↗A liquid crystal display panel of the type having reflection electrodes tends to have an image-forming plane undesirably yellowed due to the wavelength dependency of transparency observed in an orientation layer on the reflection electrodes; aluminum-neodymium alloy, which has neodymium content between 5 weight % to 10 weight %, is deposited on an inter-layered insulating layer at the substrate temperature equal to or less than 170 degrees in centigrade for the reflection electrodes so that the surface morphology is represented by average pitches equal to or less than 1 micron; even though the orientation layer has the wavelength dependency of transparency, the reflection electrodes make the optical path in the orientation layer equalized so that the image-forming plane is not yellowed.
1. A liquid crystal display panel comprising:
a bus line on a substrate;
a switching element connected to said bus line;
a reflecting electrode connected to said switching element; and
an orientation layer formed on said reflecting electrode, said orientation layer having a transmittance equal to or greater than 95% to light in an entire wavelength region between 300 nanometers and 600 nanometers.
2. A liquid crystal display panel comprising:
a bus line on a substrate;
a switching element connected to said bus line; and
a reflecting electrode connected to said switching element, wherein a reflectance of said reflecting electrode to light in an entire wavelength region between 200 nanometers and 400 nanometers is at least 90% of a reflectance to light with wavelength of 400 nanometers.
