Abstract: [Problem] The object is to provide a three-dimensional display device that can be made thin, that has superior light efficiency, and that does not increase the number of components when compared to a structure for displaying a two-dimensional image. [Means for Resolution] A first light blocking film (12) has a plurality of first fixed openings (16) for forming a plurality of pixels (14), where a single pixel (14) is formed from a pair that is a right opening RO that is made from a first fixed opening (16) and a left opening LO that is made from a first fixed opening (16). A second light blocking film (20) has a plurality of second fixed openings that are located so as to have the respective centers thereof shifted with respect to centers of any of the first fixed openings (16). The light that passes through a second fixed opening (22) travels obliquely to a right opening RO and/or a left opening LO. The respective light directed toward the right opening RO or the left opening LO is controlled to be passed or be blocked by one shutter (26). The light that passes through the right opening RO and the light that passes through the left opening LO travel in directions that are away from each other on the outside of the first substrate (10).

Abstract: This disclosure provides novel latching circuits, and pixel circuits and display devices that include such latching circuits. The latches herein include a switch positioned on an inverter coupling interconnect which couples two cross-coupled inverters of the latch. The switch is configured to control a passage of a current between the first and second inverters. By switching the switch OFF at a time a data voltage is transferred to the inverters, any leak current between the inverters can be interrupted. As a result, a malfunctioning of the data latch is prevented.

Abstract: In one innovative aspect of the disclosure, a method includes patterning a first region and a first portion of a second region of a substrate using a first reticle. The method also includes patterning the second region and a first portion of the first region using a second reticle. The method additionally includes forming a first array of first patterned elements based on the patterning by the first reticle, and forming a second array of second patterned elements based on the patterning by the second reticle. In some implementations, each of the first and the second arrays are incomplete in each of the first portions. However, the first patterned elements in the first portion of the second region are complementary to the second patterned elements in the first portion of the second region. Similarly, the first patterned elements in the first portion of the first region are complementary to the second patterned elements in the first portion of the first region. In some such implementations, the combination of the first array and the second array form a complete array of patterned elements.
