The present invention relates to a thermoplastic resin substrate for a curved mirror and a method for preparing the same, and a curved mirror and a head-up display comprising the thermoplastic resin substrate. The preparation method comprises the following steps: A) heating up a mold of an injection molding machine to a temperature in a range of 130-190° C. and closing the mold, B) injecting a molten thermoplastic resin into the cavity of the mold cavity, C) applying a pressure of 300-700 bar to the cavity for a period of 5 or more seconds, D) stopping applying pressure and cooling the mold to a temperature in a range of 60-100° C. within 10-50 seconds, and E) opening the mold and taking out the molded thermoplastic resin substrate, wherein a gap of 0.3-1 mm is left between the parting surfaces of the cavity of the mold prior to applying the pressure to the cavity. The thermoplastic resin substrate according to the present invention features a large size, high dimensional stability, and low surface roughness. It can be used for future augmented reality head-up displays to realize large-area, long-distance projection and high-precision imaging, thereby satisfying the requirements for driving safety and comfort of future automobiles.

An optical unit has an optical element reflecting light between intersecting first and second directions, and a holder. The holder includes a holder body extending in a third direction intersecting the first and second directions, and a pair of surface portions extending from the holder body in an intersection direction intersecting the third direction. The optical element is arranged between the surface portions. At least one surface portion has an inner surface facing the optical element, an end surface connected to an edge of the inner surface in an intersection direction, and a concave portion arranged astride the inner and end surfaces and recessed in the intersection direction from the end surface. The concave portion accommodates an adhesive member bonding the optical element with the holder. The length of the concave portion along the end surface is greater than the depth of the concave portion in the intersection direction.

This thermoforming machine includes a thermoforming chamber having at least one heated air inlet through which heated air flows into the thermoforming chamber at a controlled pressure. The air inlet cooperates with a heated air flow distribution regulator located in the thermoforming chamber and through which the heated air flows out of the thermoforming chamber at a predetermined temperature.
