A liquid crystal display device includes two electrode substrates and a liquid crystal layer laid between these substrates. One electrode is composed of a glass substrate with a plastics layer having plural convex portions or convex and concave portions randomly formed thereon and a lamination of a reflector, an insulating and flatting layer, a transparent electrode, and alignment layer formed on the plastics layer. The other electrode substrate is composed of a glass substrate and a lamination of a transparent electrode and alignment layer formed on the glass substrate. Both of the electrode substrates are located in a manner to allow the alignment layer of them to be opposed to each other.

A reflective color liquid crystal display apparatus, which can obtain bright images with a contrast in when viewed from any direction, is provided at a low cost. The reflective color liquid crystal display apparatus has an inside reflector and is able to produce bright images with a high contrast because unnecessary reflecting light from non-aperture portions can be decreased, and its aperture ratio can be determined approximately only by intervals of the reflective layer and intervals between the transparent electrodes. This can be accomplished by removing a reflective layer corresponding to black a matrix layer, adding a black matrix function to a polymer layer having protrusions and depressions under the reflective layer, and making a composition of its element so that a black matrix layer is not formed on the reflective layer, but only color filters are formed.

A reflective liquid crystal display apparatus with pixels includes a first electrode substrate, a second electrode substrate and a liquid crystal layer. The first electrode substrate includes a polymer layer having plural protrusions or depressions arranged randomly formed on a glass substrate, and a reflective layer, color filters, transparent electrodes, and an alignment layer formed and laminated sequentially on the polymer layer. The second electrode substrate, includes transparent electrodes and an alignment layer formed and laminated on a glass substrate, and arranged so that the alignment layer faces the alignment layer on the first electrode substrate. The liquid crystal layer is formed by filling a liquid crystal composition into an interval between the first and second electrode substrates. Portions of the reflective layer corresponding to the portions of each pixel other than apertures of each pixel are colored black.

A display apparatus is capable of adapting sufficiently to an increase in the display frequency even when using an optical modulation element which has a fairly low response speed and can rewrite an image at a high speed. The display apparatus separately performs mapping of display data for an optical modulation element of each pixel and application of gradation information. The display apparatus divides a display period of one frame into a plurality of sub-frames, controls the input value for the optical modulation element independently per each sub-frame in the plurality of sub-frames, and displays an image with a gradation display using the optical modulation element.

摘要:
A scanner device can be used in a facsimile machine or the like for reading a document on line basis. Each line of the document is read on pixel basis while irradiating a light onto the document. The scanner device includes an image sensor which receives a light reflected from the document and converts the light to an analog electrical signal. A controller controls the reading operation of the image sensor. A comparator translates the analog electric signal into a binary signal. The binary signal is stored in a shift register wherein the contents therein represents an image of a preceding line with respect to the present line being read by the image sensor. A threshold value applied to the comparator to read the present line image is varied depending upon the preceding line data stored in the shift register. As such, images on the document can be read with excellent fidelity, particularly when a fine line extending in a main scanning direction is present on the document.
