Problems solved by technology

Therefore, when an impact is received from the outside, the impact will not be absorbed by the elasticity of the base itself formed on the MEMS substrate side, but the pillars on the AP substrate side will penetrate into the base, causing the surface of the base to be damaged, and further Problems such as misalignment of pillars and bases occur

Abstract

A MEMS substrate is formed from a transparent substrate and a movable type shutter arranged on each pixel of a surface of the transparent substrate. An AP substrate includes another substrate and a light blocking film arranged on the other transparent substrate formed with an aperture corresponding to each shutter. A plurality of supporting columns is formed on a surface of the transparent substrate of the MEMS substrate. A plurality of cylindrical contact holes having the same inner diameter as an outer diameter of each supporting column are formed at a position corresponding to one part of the supporting columns. Both substrates are arranged with a certain interval so that each shutter and an aperture oppose each other, thereby a tip end of corresponding supporting columns is inserted into each contact hole and in this way, both substrate are mutually positioned.

Description

technical field [0001] The present invention relates to a display device, and more particularly to a display device including a movable shutter formed using MEMS (Micro Electro Mechanical System) technology in each pixel. Background technique [0002] As a display device, various display devices such as a plasma display device, a liquid crystal display device, and an organic electroluminescent display device are widely used. [0003] As a new type of display device, for example, as disclosed in Japanese Patent Laid-Open Publication No. 2008-197668, a display device equipped with a movable shutter formed using MEMS technology (hereinafter referred to as “MEMS display device”) has been proposed. Figure 6 and 7 An example of the movable shutter 1 formed on the transparent substrate (SUB1) is shown in . Figure 6 is a stereogram, Figure 7 is a top view. [0004] The shutter (SH) is one of the constituent elements of the movable shutter 1 , has a flat plate shape, and has an ...
