Problems solved by technology

[0009] The transflective liquid crystal display device uses the light from the backlight of the liquid crystal display panel to display under dark lighting, and reflects the surrounding light to display under bright lighting, so it can be displayed regardless of the surrounding brightness. Realizes high-contrast display, however, when the aperture ratio of the transmissive area is reduced, the brightness will decrease
[0010] In particular, in a direct-view liquid crystal display device or a single-panel projector that utilizes light absorption by a color filter for color display, the utilization efficiency of light (that is, luminance) further decreases.

Abstract

To provide an exposure apparatus suitably used for the method for manufacturing a microlens by self alignment on a color display panel. The exposure apparatus to expose a photosensitive resin layer includes an optical system emitting parallel light, a stage having an accepting face to accept the object to be exposed having a photosensitive resin layer formed thereon, and an incident angle controlling mechanism to continuously or stepwise vary the incident angle of the parallel light emitting from the optical system with respect to the accepting face of the stage.

Description

[0001] This application is a divisional application of the application with the same title filed on December 8, 2004 with the application number 200480031655.X. technical field [0002] The invention relates to a manufacturing method, a display device and an exposure device of a display panel with a microlens array. Background technique [0003] Non-self-illuminating display devices represented by liquid crystal display devices usually use driving signals to change the transmittance (or reflectance) of the display panel, and modulate the intensity of light emitted by the light source that irradiates the display panel to display images or text . Such display devices include direct-view display devices that directly observe images displayed on a display panel, and projection display devices (projectors) that enlarge and project images displayed on a display panel onto a screen using a projection lens. In addition, as non-self-luminous display panels other than liquid crystal ...
