Embodiment Construction

[0040] see Figure 8 , is a schematic plan view of a photomask used to make inclined reflective bumps according to the present invention. In this figure, the photomask 100 has three independent photomask patterns 110, 120, and 130 of different sizes, and each pattern consists of a light-transmitting part Combined with the shading part. Taking the mask pattern 110 as an example for illustration, the mask pattern 110 is roughly rectangular and formed by merging the light-transmitting portion 113 and the light-shielding portion 111 . The light-shielding portion 111 is basically a rectangular block-shaped area, one side of which is connected to the light-transmitting portion 113 has a plurality of rectangular protrusions 112 in the plane direction of the mask, while the other three sides are flat.

[0041] The plurality of rectangular protrusions 112 have a width of 1-3 μm and a length of 0-5 μm. In this embodiment, the width s is 1 μm, and the length h and the interval d are equ...

Abstract

This invention discloses a blend used in producing tilted reflection projectors including multiple patterns bridged by penetration parts and shading parts, among which, said penetration part or the shading part is block zone, one side of the block zone has many projectors on the blend plane direction. The processing method is also disclosed.

Description

【Technical field】 [0001] The invention relates to a photomask (Photo Mask) and a method for making an inclined reflective bump (Bump) using the photomask, in particular to a photomask for making reflective or transflective (Transflective) A photomask used in liquid crystal display devices (Liquid Crystal Display Devices, LCD Devices) and a method for using the photomask to manufacture inclined reflective protrusions in reflective liquid crystal display devices. 【Background technique】 [0002] Liquid crystal display devices have the advantages of lightness, thinness, low power consumption, and digitization, and are currently more and more widely used in the market. Liquid crystal display devices can be classified into transmissive, reflective and transflective according to their light source utilization methods. For reflective or transflective liquid crystal display devices, both brightness and viewing angle must be considered. Reflective or semi-transmissive semi-reflectiv...
