Liquid Crystal Display

Abstract

A liquid crystal display which can reliably adhere an elastic layer which is liable to warp easily to a rigid layer is provided. (a) An elastic front window is adhered to a rigid touch panel by way of an adhesive sheet. (b) An elastic touch panel is adhered to a rigid liquid crystal panel by way of an adhesive sheet, and an elastic front window is adhered to the elastic touch panel byway of an adhesive sheet. (c) An elastic touch panel is adhered to a rigid liquid crystal panel by way of an adhesive sheet and, thereafter, a rigid front window is adhered to the elastic touch panel by way of an ultraviolet-curing adhesive material. (d) An elastic touch panel is adhered to a rigid front window by way of an adhesive sheet and, thereafter, a rigid liquid crystal panel is adhered to the elastic touch panel by way of an ultraviolet-curing adhesive material.

1 . A liquid crystal display comprising:
 a first substrate;   a second substrate which is arranged to face the first substrate in an opposed manner such that a liquid crystal layer is sandwiched between the first substrate and the second substrate;   a semiconductor element which is mounted on a region of a liquid-crystal-layer-side surface of the first substrate excluding a region where the first substrate faces the second substrate;   a polarizer which is arranged on the second substrate;   a touch panel which is adhered to the polarizer by way of a first adhesive layer, and allows one edge thereof to face at least a portion of the region where the semiconductor element is mounted; and   a front window which is adhered to the touch panel by way of a second adhesive layer, wherein   a thickness of the semiconductor element is smaller than a sum of a thickness of the polarizer and a thickness of the second substrate.   
     
     
         2 . A liquid crystal display according to  claim 1 , wherein the thickness of the semiconductor element is smaller than a sum of one half of the thickness of the polarizer and the thickness of the second substrate. 
     
     
         3 . A liquid crystal display according to  claim 1 , wherein the thickness of the semiconductor element is larger than the thickness of the second substrate. 
     
     
         4 . A liquid crystal display comprising:
 a first substrate;   a second substrate which is arranged to face the first substrate in an opposed manner such that a liquid crystal layer is sandwiched between the first substrate and the second substrate;   a semiconductor element which is mounted on a region of a liquid-crystal-layer-side surface of the first substrate excluding a region where the first substrate faces the second substrate;   a polarizer which is arranged on the second substrate;   a touch panel which is adhered to the polarizer by way of a first adhesive layer; and   a front window which is adhered to the touch panel by way of a second adhesive layer, wherein   one edge of the touch panel projects from a region which faces the semiconductor element in an opposed manner so as to prevent the one edge of the touch panel from coming into contact with an upper surface of the semiconductor element when the one edge of the touch panel is displaced in the first substrate direction.   
     
     
         5 . A liquid crystal display comprising:
 an IPS type liquid crystal panel which includes a first substrate on which a plurality of pairs of electrodes each of which has a pixel electrode and a counter electrode are formed, a second substrate which is arranged to face the first substrate in an opposed manner such that a liquid crystal layer is sandwiched between the first substrate and the second substrate, and a polarizer which is arranged on the second substrate;   a touch panel which is adhered to the polarizer by way of an adhesive layer; and   a conductive tape which electrically connects a ground electrode which is formed on a region of a liquid-crystal-layer-side surface of the first substrate excluding a region where the first substrate faces the second substrate and a conductive film formed on the second substrate with each other.   
     
     
         6 . A liquid crystal display according to  claim 5 , wherein a thickness of the conductive tape is smaller than a thickness of the polarizer. 
     
     
         7 . A liquid crystal display according to  claim 5 , wherein the conductive tape is adhered to the ground electrode and the conductive film respectively by thermocompression bonding. 
     
     
         8 . A liquid crystal display according to  claim 5 , wherein the touch panel is an electrostatic-capacitance-type touch panel.
