Embodiment Construction

[0023] Hereinafter, embodiments of the present invention will be described with reference to the drawings. figure 1 It is a sectional view showing the outline of the display device in the embodiment of the present invention. figure 2 It is an enlarged perspective view of a part of the internal structure of the display device. image 3 as well as Figure 4 is a plan view of the internal structure of the display device.

[0024] The display device has a pair of light-transmitting substrates 10 and 12 (for example, glass substrates). The pair of light-transmitting substrates 10 and 12 are disposed so as to face each other with a gap therebetween. On the one light-transmitting substrate 10 , a light-shielding film 34 is formed on the side facing the other light-transmitting substrate 12 . like figure 2 As shown, a plurality of fixed openings 36 through which light passes through are formed on the light shielding film 34 .

[0025] The plurality of fixing openings 36 are el...

Abstract

The present invention has an object to solve the problem in viewing angle characteristics. A display device of the present invention includes: a light shielding film (34) including a plurality of fixed apertures (36); a plurality of shutters (14) for controlling passage and blocking of the light (L); and a drive portion (40) for driving each of the plurality of shutters (14) to move between a position above the plurality of fixed apertures (36) and a position retracted from the plurality of fixed apertures (36). The plurality of fixed apertures (36) each have an elongated shape including a long-side direction and a short-side direction, and include: fixed apertures (36a) of a first group in which the long-side direction is directed in a first direction (Y); and fixed apertures (36b) of a second group in which the long-side direction is directed in a second direction (X) orthogonal to the first direction (Y). The plurality of shutters (14) include: shutters (14a) of a first group, which correspond to the fixed apertures (36a) of the first group, respectively, and are linearly driven in the second direction (X); and shutters (14b) of a second group, which correspond to the fixed apertures (36b) of the second group, respectively, and are linearly driven in the first direction (Y).

Description

technical field [0001] The invention relates to a display device. Background technique [0002] MEMS displays (Micro Electro Mechanical System Displays) are expected to replace liquid crystal displays (see Patent Document 1). Unlike the liquid crystal shutter type that uses polarized light, this display displays brightness and darkness by mechanically opening and closing the light transmission window with a shutter unit having a fixed opening and shutter. Specifically, light is blocked by disposing a shutter above the fixed opening, and light is transmitted by moving the shutter away from above the fixed opening. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2008-197668 [0004] The fixed opening is constituted by an opening formed in the light-shielding film, and the shutter is drivable by being spaced apart from the light-shielding film. Therefore, when the shutter is moved away from above the fixed opening, light traveling perpendicular to the screen is tra...
