The present invention provides an optical film composite that includes a linear, reflective polarizing film; a first polymeric substrate layer having birefringence, which is placed on the reflective polarizing film; and a second polymeric substrate layer placed beneath the reflective polarizing film, wherein the optical axis of the first polymeric substrate layer is oriented with respect to the transmission axis of the reflective polarizing film to have of 0&#xb0; to 25&#xb0; of an angular difference between the axes. The optical film composite can be employed in LCD devices to improve optical performance.

In a directly-illuminated liquid crystal display (LCD), for example an LCD monitor or an LCD-TV, a number of light management films, including a diffuser layer, lie between the light source and the LCD panel to provide bright, uniform illumination. The diffuser layer is attached to a substrate which is separate from the light source and the LCD panel, or may be attached to either the LCD panel or, when using a two dimensional light source, to the light source. The other light management layers may also be attached to the separate substrate or to the LCD panel or two-dimensional light source. High levels of illumination uniformity at the LCD may be achieved with a uniform (non-patterned) diffuser, even with relatively low levels of diffusion, when the diffuser is used with a brightness enhancing layer.

The present invention provides a silane oligomer for immobilizing a physiological material that is prepared by copolymerizing an aminosilane compound with a cyclic siloxane oligomeric compound. The present invention can preserve the immobilization layer by applying a silane oligomer. Further, the immobilization layer has a three-dimensional structure and thus has superior thermal stability and reagent resistance.

Provided a transparent conductive layer and an image display device employing the transparent conductive layer. The transparent conductive layer includes a conductive layer containing a metal oxide and a protective layer formed on the conductive layer. The protective layer contains a hydrolyzed and polycondensated product of silicon alkoxide and at least one of mercapto compound and its hydrolyzed and polycondensated product.
