  • Display units having two insolating films and a planarizing film and process for producing the same
    Patent number: 5721601
    Abstract: A liquid crystal display unit is described, which includes a first substrate, a second substrate opposing to the first substrate, pixel driving elements, first and second insulation layers, a planarizing film and a liquid crystal layer. The pixel driving elements are disposed on the first substrate and between the first and second substrates. The first insulation layer is deposited over the first substrate and the pixel driving elements. The planarizing film is formed on the first insulation layer. This planarizing film provides a substantially flat surface over the first substrate to minimize a height of a step present between an area corresponding to each pixel driving element and an area locating adjacent to the pixel driving element on the first substrate. The second insulation layer is formed on the planarizing film. The display electrodes are formed on the second insulation layer and electrically connected to the pixel driving elements, respectively.
