Abstract: The present invention provides a semi-transmissive or reflective liquid crystal display device in which gray scale inversion is suppressed by appropriately adjusting its voltage-reflection luminance characteristics. The liquid crystal display device of the present invention is a liquid crystal display device including: a pair of substrates; and a liquid crystal layer interposed between the pair of substrates, wherein the liquid crystal display device includes a transmission region and a reflection region, the reflection region includes a first section and a second section, a thickness of the liquid crystal layer in the first section is larger than half of but equal to or smaller than a thickness of the liquid crystal layer in the transmission region, and a thickness of the liquid crystal layer in the second section is larger than the thickness of the liquid crystal layer in the transmission region.

Abstract: In a liquid crystal display device which presents display by forming liquid crystal domains that take radially-inclined orientation, persisting display unevenness is prevented from occurring when the panel surface is pressed, thus realizing high-quality displaying. A liquid crystal display device according to the present invention includes a first substrate, a second substrate provided so as to oppose the first substrate, and a vertical-alignment type liquid crystal layer provided therebetween. The liquid crystal display device according to the present invention further includes wall-like structures regularly arranged on the liquid crystal layer side of the first substrate, such that, when a predetermined voltage is applied, the liquid crystal layer forms at least one liquid crystal domain that takes a radially-inclined orientation state in a region substantia y surrounded by the wall-like structures.

Abstract: With the present invention, a fitting curve (f1) of the gamma curve (e1) arranged to be above a fitting curve of the gamma curve (e2), except in a region where the fitting curve (f1) shows a reflectivity of 0 and the fitting curve of the gamma curve (e2) shows a transmissivity of 0, and a gamma curve (e1) of reflective display and a gamma curve (e2) of transmissive display are obtained from measurement. Further, the fitting curve (f1) includes no gray scale inversion but at least one point of inflection (P1) where a sign of a differential coefficient is switched over. Thereby, it becomes possible to realize a liquid crystal display panel and a liquid crystal display device, for displaying images in a transmissive mode and a reflective mode, each of the liquid crystal display panel and the liquid crystal display device easily having an improvement in display quality of reflective display.

Abstract: A false act of a clerk at a store is monitored at a host computer under utilization of a communication network by detecting a false key operation in reference to a count which can be flexibly set in an item sales register or the like. The sales processing unit reads out in sequence the stored function numbers, collates them with the function numbers of the depressing limit in sequence, and if the result shows a coincided state, the sales processing unit adds 1 to the limit counter of the corresponding key, compares the value of the limit counter of the corresponding key with the corresponding limit count of the depressing limit master, and if the value of the limit counter exceeds the limit count, the sales processing unit outputs to the communication unit an instruction that the fact showing of the depressing action of the corresponding key exceeded the limit count is sent to the host computer, and causes the communication unit to send it.
