A seal segment as described for a seal segment ring of a turbine in a gas turbine engine. An ellipticity of elliptically polarized light, which is incident on the liquid crystal display panel LPN in a principal viewing-angle direction is greater than an ellipticity of elliptically polarized light, which is incident in a anti-principal viewing-angle direction. The differences in turnoff current cause the second snapback device to turn off prior to the first snapback device at the conclusion of an ESD event. In yet other embodiments, the invention relates to semiconductors and devices comprising a composition of the invention.
