    摘要: A probe structure containing a contact part (2) formed on one side (1a) of an insulating substrate (1), a conductive circuit (3) formed on the other side (1b) of the insulating substrate (1), wherein the contact part (2) and the conductive circuit (3) are connected via a conductive path (5) formed in a through-hole (4) in the thickness direction of the insulating substrate (1). The contact part (2) has a structure containing a deep layer (1c) having a hardness of 100-700 Hk, an intermediate layer (1b) having a hardness of 10-300 Hk, and a surface layer (1a) having a hardness of 700-1200 Hk successively laminated. The surface layer (1a) preferably has a tensile stress of not more than 50 kg/mm.sup.2. The probe structure maintains low and stable contact resistance in an electric test, in particular a burn-in test, of small test objects such as IC. In a test method wherein a solder bump is formed in a test object and utilized, the solder component of the test object does not adhere to the contact part (2) after testing. The probe structure suffers less from deterioration of contact state after repetitive open/close contact with the test object as compared to the initial contact state, and highly reliable electric testing can be performed.

    摘要: In a liquid-crystal display device, an optical path control layer is provided at least on an outer side of the back side substrate, and has a plurality of optical path changing slopes inclined at an inclination angle of from 35 to 48 degrees with respect to a reference plane of the back side substrate. The optical path control layer has a refractive index higher than that of a low-refractive-index transparent layer provided in the back side substrate. Another low-refractive-index transparent layer lower in refractive index than the transparent substrate may be provided in a visual side substrate. Light sources may be disposed on at least two side surfaces of the liquid-crystal display panel. Light sources may be disposed on side surfaces of the back side substrate and the visual side substrate and at least on side surfaces of the liquid-crystal display panel which are different from each other. Another optical path control layer may be provided also on an outer side of the visual side substrate.
