Abstract: A pixel electrode or a common electrode is a light-transmissive conductive film; therefore, it is formed of ITO conventionally. Accordingly, the number of manufacturing steps and masks, and manufacturing cost have been increased. An object of the present invention is to provide a semiconductor device, a liquid crystal display device, and an electronic appliance each having a wide viewing angle, less numbers of manufacturing steps and masks, and low manufacturing cost compared with a conventional device. A semiconductor layer of a transistor, a pixel electrode, and a common electrode of a liquid crystal element are formed in the same step.

Abstract: A display device includes a display module, a window disposed above the display module, an optical film disposed between the display module and the window, an adhesive layer, and a refractive index matching pattern. The window includes a base substrate and a bezel pattern overlapping with the base substrate and defining a first transmissive area and a second transmissive area isolated from the first transmissive area in a plane view. The optical film includes a first open area defined therein to correspond to the second transmissive area. The adhesive layer couples the window with the optical film. The refractive index matching pattern is disposed in the first open area and has a refractive index of about 90% to about 110% of the adhesive layer. The first open area is defined as an area in which the optical film is not disposed.

Abstract: A display includes a transmissive Spatial Light Modulator (SLM), and a second backlight having a film-based lightguide disposed above a first backlight. The first backlight may emit first light out of a first light emitting surface in a first light emitting region with a Full-Angular Width at Half-Maximum Luminous Intensity (FAWHMLI) in a first light output plane greater than 60 degrees. The second backlight may emit second light from a second light emitting surface in a second light emitting region positioned above the first light emitting region with a FAWHMLI in a second light output plane orthogonal to the second light emitting surface less than 50 degrees. In a first display mode, the first light passes through the film-based lightguide, and the first light emitting surface and illuminates the transmissive SLM, and in a second display mode the second light illuminates the transmissive SLM.
