ABSTRACT:
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.
