摘要： In the present embodiment, a sealing agent (50) sealing two substates contains a low melting-point glass material and is adhered to each of a first substrate (10) and a second substrate (20), a barrier rib (60), which is formed in such a manner as to surround the outer periphery of an electronic element (30), is disposed between the sealing agent (50) and the electronic element (30), and between the first substrate (10) and the second substrate (20), and the sealing agent (50) is spaced apart from the barrier rib (60). As a result, a deterioration of the electronic element, caused by the heat produced when sealing, may be prevented while the electronic element formed between the two substrates is protected from moisture and oxygen.

摘要： The present invention provides a liquid crystal display device of a transverse electric field mode that may inhibit internal reflection and realize proper black display to which coloring does not occur. The present invention provides a liquid crystal display device including a first linear polarizer, a first λ/4 retardation layer, a first substrate, a second λ/4 retardation layer configured with a different material from the first λ/4 retardation layer, a liquid crystal layer that contains liquid crystals which are horizontally aligned in a case where no voltage is applied, plural electrode pairs that generate a transverse electric field in the liquid crystal layer by a voltage being applied, a second substrate, a second linear polarizer, and a backlight. In a case where a color of light emitted from the backlight is expressed by using chromaticity coordinates (x, y) of an XYZ color system, both of x and y are 0.32 or greater. The plural electrode pairs include a red electrode pair arranged in a red sub-pixel, a green electrode pair arranged in a green sub-pixel, and a blue electrode pair arranged in a blue sub-pixel. A white display applied voltage of the blue electrode pair is different from the white display applied voltage of the red electrode pair and the white display applied voltage of the green electrode pair.

摘要： A liquid crystal display panel performs displaying in the normally white mode. A first and a second polarizer are disposed so that the transmission axes thereof are perpendicular to each other. A liquid crystal layer is in a twisted alignment state in the absence of an applied voltage. A first substrate has a first electrode having a plurality of rectangular openings extending in parallel to each other, and a second electrode facing the first electrode with a dielectric layer interposed therebetween. The openings each independently have a width S of more than 0.6 μm and not more than 1.4 μm, and each pair of adjacent openings independently has a distance L therebetween of not less than 0.3 μm and not more than 0.7 μm. A first and a second horizontal alignment film each have an azimuthal anchoring energy of not more than 1×10−4J/m2.
