Abstract:
A LCD panel includes a LC layer, an active-matrix substrate including an electrode layer for applying a lateral electric field to the LC layer, and a counter substrate opposing the active-matrix substrate with an intervention of the LC layer 11. The active-matrix substrate includes a first alignment film formed in the surface which touches the LC layer 11 by the rubbing technique is formed, and second alignment film 35 formed in the surface which touches the LC layer 11 by the particle beam glaring technique is formed on the counter substrate 13.
Abstract:
An LCD device is obtained by joining a counter substrate and a TFT substrate with a sealing member having at least a UV-curable characteristic. The sealing member includes a UV-curable resin and high-refractive layers formed respectively on the surfaces of spacers which are dispersed in the UV-curable resin, each of the surfaces of the spacers having a refractive index higher than that of the UV-curable resin.
Abstract:
In a liquid crystal display panel, a gap between an array substrate 2a and an opposing substrate 3 is made constant by using spacers 23 mixed in a seal agent 22 provided around a display area A. A bottom-up pattern 17 formed in the same layer as that of a light shield 16 is formed in a seal area B and a leveling layer 19 on the seal area B is made thinner in order to minimize an amount of sink of the spacers 23 into the leveling layer 19 thereby make the gap between the substrates uniform.
Abstract:
In a liquid crystal display panel comprising first and second substrates which are spaced from each other at a predetermined gap, and liquid crystal sealed in the gap between the pair of first and second substrates, the panel gap between the first and second substrates is controlled by two kinds of gap control materials dispersed in a seal material on the outer periphery of said panel. The two kinds of gap control materials consist of a first gap control material of particles softer than an insulating film (back film) and wires disposed on the first substrate, and a second gap control material of particles harder than the insulating film (back film) and the wires disposed on the first substrate, and the maximum particle diameter in consideration of the standard deviation of the first gap control material is set to be larger than the maximum particle diameter in consideration of the standard deviation of the second gap control material.
Abstract:
A piezoelectric transformer includes a molded package having first and second inner walls facing each other, a plurality of pairs of projections provided on the first and second inner walls, and a piezoelectric transformer element mechanically supported by the projections so that the piezoelectric transformer element is accommodated in an internal space defined by inner walls of the molded package but separated from the inner walls of the molded package. As a result, the thickness of the package can be reduced.
Abstract:
An active matrix substrate is provided with a lead wire led out from a switching element to a surrounding region; a pad portion formed in the lead wire, and positioned in surrounding region; an insulation layer formed so as to cover pad portion, including a passivation film formed of an inorganic material, and a planarization film positioned on passivation film and formed of an organic material, and having a contact hole formed so as to reach pad; and an ITO film positioned in contact hole, and formed on pad. ITO film is formed so as to be spaced from a part defined by planarization film in an inner periphery surface of contact hole.
Abstract:
A method of fabricating a liquid crystal display device, includes applying an alignment film to a substrate surface, provisionally drying the alignment film, baking the alignment film; rubbing; and rubbing washing, which are performed in this sequence, wherein, in applying the alignment film, the alignment film is formed so as to cover at least a display region, and a portion of the alignment film which extends in a region outside the display region is imparted with an adsorptive property by modification during a process from the provisional drying to the rubbing washing.
Abstract:
In applying an alignment material to surfaces of a CF substrate and a TFT substrate, which form a liquid crystal panel, to form alignment films, an alignment film is formed so as to cover at least a display region in which pixels are arranged in a matrix fashion, while a porous alignment film, which has a porous film structure with a higher impurity adsorptive property than the former alignment film, is formed in a region outside the former alignment film, for example, in a region intermediate the display region and a seal region surrounded by a sealing material, whereby the porous alignment film formed in the region outside the display region can efficiently adsorb contaminants, such as residual impurity ions produced from the sealing material and uncured components of the sealing material, to prevent the contaminants from penetrating into the display region and being fixed therein.

Abstract:
A manufacturing method of the present invention is applied to manufacture of a liquid crystal display device comprising an array board, an opposing board opposing the array board, and a liquid crystal layer interposed between the pair of boards. The method includes a step of performing alignment processing on an alignment film formed on the surface of at least one of the pair of boards in contact with the liquid crystal. The alignment processing is performed by irradiating energy having an anisotropy such as ion beams to the alignment film in a plurality of steps while the energy intensity is set to be lowest in the final irradiation step.
