摘要： It is an object of the present invention to form a pixel electrode and a metal film using one resist mask in manufacturing a stacked structure by forming the metal film over the pixel electrode. A conductive film to be a pixel electrode and a metal film are stacked. A resist pattern having a thick region and a region thinner than the thick region is formed over the metal film using an exposure mask having a semi light-transmitting portion. The pixel electrode, and the metal film formed over part of the pixel electrode to be in contact therewith are formed using the resist pattern. Accordingly, a pixel electrode and a metal film can be formed using one resist mask.

摘要： Diffractive optical structures, lenses, waveplates, devices, systems and methods, which have the same effect on light regardless of temperature within an operating temperature range. Temperature-compensated switchable diffractive waveplate systems, in which the diffraction efficiency can be maximized for the operating wavelength and temperature by means of adjustment of the electric potential across the liquid crystal or other anisotropic material in the diffracting state of the diffractive state, based on prior measurements of diffraction efficiency as a function of wavelength and temperature. The switchable diffractive waveplates can be a switchable diffractive waveplate diffuser, a switchable cycloidal diffractive waveplate, and a switchable diffractive waveplate lens. An electronic controller can apply an electric potential to the switchable diffractive waveplate. Amplitudes of the electric potential can be determined from lookup tables such that diffraction efficiency at an operating wavelength and measured temperature is maximized. A communications channel can transfer the measured temperature from temperature measurement means to the electronic controller.
