Transmission type display element

Abstract

Abstract PURPOSE:To obtain a display of a bright image plane by providing a light condensing body having a micro-arrangement on the rear of a supporting substrate of a transmission type and photodetection type display element and condensing the incident light from the rear of the substrate to each picture element. CONSTITUTION:A light condensing body made of acrylic, etc. having a semicircular cylindrical micro-lens array 11 is provided on the surface of an element of a photodetection type and transmission type such as liquid crystal display, electrochromic display or the like on the side opposite to the surface provided with a thin film transistor 2, a drain electrode 3 and a gate electrode (display electrode) 5 on one transparent substrate 1. The rays 20, 21, 22 made incident on the lens array body 11 are concentrated through the substrate 1 on a display aperture part 12, i.e., display electrode 5. The display image of, for example, the display element which is provided with a common electrode 7 and a color filter 8 on a counter substrate 6 and is sealed therein with a liquid crystal 10 is displayed brightly. The lens arrangement may be an array consisting of spherical lenses or a lens array made into a V-shaped groove type or trapezoidal shape.
