摘要： An optical sensor circuit in accordance with the present invention detects, based on a change in the amount of light received when a pointer (P) is placed in a coordinate detection area (2) through which light from a light source (3) passes, coordinates of a position of the pointer (3) in the coordinate detection area (2). A first optical sensor circuit including an optical sensor element (41), which receives a larger amount of light due to its position relative to the light source (3), has a first wire to which a refresh signal (Shield_A) is supplied, the refresh signal (Shield_A) initializing a threshold characteristic that determines light sensitivity of the optical sensor element (41); whereas a second optical sensor circuit including an optical sensor element (42), which receives a smaller amount of light, has a second wire to which a refresh signal (Shield_B) is supplied independently of the refresh signal (Shield_A), the refresh signal (Shield_B) initializing a threshold characteristic of the optical element (42).

摘要： In a liquid crystal display device including an array substrate which is provided with contact holes and a counter substrate which is provided with integral spacers and aligned with the array substrate, an overall region including every pixel region is divided into a plurality of subregions, each of which includes two or more said spacers and is composed of at least one said pixel region. The spacers are so arranged that when one or some of the spacers are positioned to get into the corresponding contact holes, the rest of the spacers are positioned off the corresponding contact holes. By so doing, a uniform gap is provided between the substrates even if accuracy in aligning the substrates with each other is not considerably high.
