    Abstract: A liquid crystal display having satisfactory visibility in a wide viewing angle range is provided. A TFT array substrate of the liquid crystal display includes scanning electrodes and signal electrodes arranged in a matrix shape, thin-film transistors respectively disposed at intersections between the scanning electrodes and the signal electrodes, first pixel electrodes respectively connected to the signal electrodes via the thin-film transistors, connecting capacitor electrodes formed in a layer including gate electrodes of the thin-film transistors, and second pixel electrodes capacitively connected to the first pixel electrodes via the connecting capacitor electrodes. It is not necessary to use any additional process to form the second electrodes, leading to advantages that the product yield is improved and production cost is lowered. Each pixel is divided into plural areas having different directions of orientation and into plural areas being applied with different voltages. Due to existence of the areas having different directions of orientation, there is attained a vertically symmetric transmittivity characteristic. Moreover, adjusting the surface ratio and the application voltage ratio between the areas to be applied with different voltages, there are attained an advantageous effect that viewing angle dependence is relaxed in the low gradation presentation and visibility is improved.

    Abstract: A planar light source, Fresnel lens sheet, and louver are disposed in the stated order in a light source apparatus. The Fresnel lens sheet deflects and focuses in one dimension light that has entered from the planar light source. The louver is disposed in the optical path of the light emitted from the Fresnel lens sheet, and the directivity of the light can be increased by restricting the traveling direction of the light to the focal direction of the Fresnel lens sheet. The light utilization ratio can thereby be increased, the directivity of planarly emitted light can be increased, and the brightness can be made uniform at the point of observation.
